• Effect of polymer and pesticide coating on viability, vigour and longevity of cotton seeds- Seed treatment with imidaclorpid @ 5 g kg-1 alone or coated with polymer @ 5 ml kg-1 + carbendazim @ 2 g kg-1 is effective in control of sucking pests up to 45 days after sowing. Coating of seeds with polymer @ 5 ml kg-1 or polymer + carbendazim or polymer + cabendazim + imidacloprid or Chlothianidine or Thiamethoxam either alone or in combination prolonged the seed viability and quality for a period of sixteen months.
• Effect of relative humidity levels on physiological and biochemical changes in cotton seed during storage –With an increase of storage period and relative humidity there was a progressive decline in viability, dry matter of seedling, vigour, seed oil content, coupled with rapid increase of seed moisture content, free fatty acid accumulation, electrical conductivity of seed leachate, free sugars and storage fungi in all the genotypes Anjali, Surabhi, LRA5166 and AKH4 stored at 40%, 60%, 80% relative humidity and along with silica gel (Control) for eight months under ambient condition.
• Effect of seed treatments on the maintenance of viability and vigour in cotton seeds under ambient storage-Freshly harvested and delinted seeds of cotton varieties LRA 5166 (treated with neem leaf powder @ 10g kg-1) and Surabhi (treated with neem kernel powder @ 10g kg-1) packed in paper bag and stored under ambient condition for 32 months, excelled other treatments by registering higher seed quality with extended the storage life.
• Influence of spacing and micronutrient spray on yield and quality of seed-Sequential foliar application with diammonium phosphate 2 %, MgSO4 1 %, boron 0.1 %, ZnSO4 2 % at 45, 50, 60, 75 days after sowing enhanced the seed cotton and quality seed yield at 120 x 60 cm spacing in Cv.Anjali
• Detopping with defoliation treatment maximizes seed yield in cotton-The beneficial effects of detopping at 120 days and spraying of ethrel @ 450 g a.i. acre-1 at 160 days after sowing exhibited in terms of reduced plant height with increased number of sympodia, bolls, boll weight, seed cotton yield and seed yield in LRA 5166
• Seed soaking and foliar application of hormones and nutrients for enhancement of productivity and quality of cotton seed- Seed soaking in succinic acid @ 0.2% and spraying of NAA @10 ppm on 60 and 75 days enhanced the field emergence (4%), plant stand establishment (98%), Seed cotton yield and quality seed yield in cv.Sumangala.
• Enhancement of hybrid cotton seed yield and quality through parental crop management- In hybrid Savitha, the boll setting efficiency was high due to pollination in the early phases of flowering (up to 5th week) and there on declined significantly. Seeds formed during that period were highly vigorous and viable. The parental seed crop management with seed soaking treatment and foliar application of growth hormones and nutrients indicated that soaking of female parent seeds in succinic acid @ 0.2 % for six hours before sowing and pollination up to five weeks from flower initiation and simultaneously foliar application of boron @0.1 % at 60 DAS, MgSO4 1 % at 75 DAS or foliar application of boron @ 0.1 % at 60, 75 & 90 DAS alone found good for production of high quality hybrid seed.
• Control of seed deterioration in cotton genotypes-Cotton seeds stored under laboratory conditions for one, two, three and four years, dry dressed with a mixture of calcium oxychloride and calcium carbonate (3:1) @ 5 g kg-1 and iodine vapours impregnated in the calcium carbonate @ 3g kg-1 and kept in airtight container under ambient condition for seven days had shown increased seed vigour and viability due to halogenation, irrespective of age of seeds and reduced the pathogenicity tested in cv. 70 E, Bikaneri Narma, AC.738, PIL.43,PIL.8, .7 and M.12 stored seeds.
• Performance and productivity of F1 and F2 seeds of Intra hirsutum hybrids-The morphological and reproductive traits of ten F2 generations of pre released intra hirsutum hybrids were compared along with F1. A decrease in plant height, sympodia plant-1, seed index and lint index in F2 over F1 was observed in all the cultures. However an increase in the number of bolls plant-1 and seed cotton yield plot-1 was observed in H1, H2, H4, H7, H9, H10, Savita and NHH 44. The fiber property of F2 plants such as 2.5%span length of H3, H6, was on par with savita. Uniformity ratio of H1, H2, H4, H7, H9, and H10 found superior to either of Savita and NHH 44. The micronaire of all the cultures was on par with NHH 44 and inferior to Savita. The fiber elongation of H7 and H9 were superior to Savita and NHH44.
• Comparison of performance of model bulk, superior bulk and ordinary bulk of plants selected from progenies- In LRA5166 and Sumangla pooled seeds of single plant progenies of superior bulk (A), model bulk (B) and ordinary bulk (C) were raised along with breeder seed (BS). The plants from superior bulk of both the varieties came to flowering earlier than the ordinary bulk. In case of LRA 5166, the model bulk performed equally with superior bulk and breeder seed. The number of sympodia recorded was maximum especially in superior bulk of sumangala (15.6) when compared with ordinary bulk (13.7). Superior bulk of LRA 5166 and model bulk of sumangala showed better performance for morphometric character such as plant height. Maximum yield/ha was recorded in model bulk of Sumangala followed by breeder seed of LRA 5166. Better performance for fiber quality parameters like span length and bundle strength was registere in superior bulk followed by model bulk and breeder seed.
• Cataloguing (a) morphological and (b) genetic marker using molecular technique available in the currently cultivated cotton varieties and hybrids- Morphological markers of cotton varieties LRA5166 and Sumangala (G. hirsutum) were studied for easy identification during winter 2003, 2004, 2005, seasons using breeder seeds. The visible morphological characters such Seedling pigmentation, Growth habit, Density of foliage, Plant: Stem hairiness, Pubescence on stem Bract: number of serration No. of teeth in the bracts Boll surface Fibre: strength Fibre: fineness (micronaire value) were found useful in variety and hybrid identification. Genetic marker-The genomic DNA from single seed of hybrid Savita and its parents T7 (female) and M12 (male) was isolated and random primers were used for RAPD analysis. The primer OPA 01, 02 and 03 showed the presence of DNA sequence in female, hybrid and male parent of hybrid Savita. The primer OPC 06 very clearly indicated the presence of similar DNA sequence in hybrid and parents. The primer OPA 07 and 08 indicated the presence of male and female specific DNA sequences which are present in hybrids. These DNA segments help to identify the presence of male or female seeds in the hybrid seed lot.
• Effect of supplemental foliar nutrients on seed yield and quality of cotton seed-In Anjali seed crop, foliar application of DAP @ 2 % + Boron @ 0.6 Kg/ha + Zinc @ 0.5% on 70, 90 and 110 days after sowing significantly improved the seed quality and recorded higher seed yield. Application of DAP @ 2 % (T1), Boron @ 0.6 Kg/ha (T2), Zinc @ 0.5% (T3) individually exhibited positive effect on seed quality improvement, and the beneficial effect is high when it is applied simultaneously.
• Enhancement of planting quality of seed and stand establishment of cotton through sequential pelleting-The delinted seeds of cotton cv. Anjali were coated using Polymer @ 3g kg-1 with following ingredients for pelleting. Seed protectant: Bavistin @ 2g kg-1, Thiram @ 2g kg-1, Cruiser @ 3g kg-1, Imidacloprid @ 7g kg-1; Bio inoculants: Trichoderma viridie @ 4g kg-1, Pseudomonas florescence @ 10g kg-1; Nutrients: DAP @ 20g kg-1, Micro nutrient mixture@ 10g kg-1 and Gypsum @ 20g kg-1; Botanicals: Arappu leaf powder @ 50g kg-1 (Albizia amara), Neem leaf powder (Azadirachta indica) @ 20g kg-1 and Turmeric (Cucumin sp) rhizome powder @ 20g kg-1 . Following are the best five combination and sequence of coating for seed quality improvement. 1.Thiram + Gypsum + Micronutrient + Gau chao + DAP, 2. Thiram + DAP + Gau chao+ Micronutrient + Gypsum, 3. Arappu leaf powder + Turmeric rhizome powder + Neem leaf powder, 4. Neem leaf powder + Turmeric rhizome powder + Arappu leaf powder, 5. Bavistin+ Neem leaf powder + Arappu leaf powder + Turmeric rhizome powder
• Standardization of laboratory techniques for variety identification-Seed physiological laboratory techniques such as Phenol test, Modified phenol colour reaction, test, Ferrous sulphate test, Potassium hydroxide test, Sodium hydroxide test, GA3 soak test, 2,4-D soak test, Hydrogen peroxide soak test were conducted to assess the reaction and physiological expression of the cotton hybrid and their parental seeds. The hybrids used are HB 224 (LRA 5166 x P 4), Surya (T 13 x M 12), Savita (T 7 x M 12), Varieties: Surabhi, Anjali, Supriya, and SVPR 2. The observations revealed the following Phenol test: no response to phenol test; hence no grouping could be possible; Modified phenol test: no response to modified phenol test, hence no grouping could be possible; Ferrous sulphate test: all the genotypes turned into black colour; Potassium hydroxide test: The cotton genotypes could be classified based on colour development; Sodium hydroxide soak test: The cotton genotypes could be classified based on colour development; GA3 soak test: Based on hypocotyl length the cotton genotypes were grouped into three categories; 2, 4-D soak test: no genotypes germinated at 0.5 ppm, 2, 4-D solution; Hydrogen peroxide soak test: Based on the response of cotton genotypes to hydrogen peroxide, the genotypes studied were classified.
• Variety Identification of cotton genotypes through electrophoresis- Variety Identification of cotton genotypes through electrophoresis were conducted for the development of predictable banding pattern due to single seed protein globulin in cotton seed. Initially total soluble protein from hybrids Savita (T7 x M12) and Kirti (Suman x BN) were extracted and loaded in an SDS-PAGE and run in a gel unit. The gel indicates proper formation of bands due to differential movement of protein molecules. Cotton varieties like Anjali, LRA5166, Sumangala, L 604, Sahana, PKV Rajat, Suvin, K9, K10, K11, AKH-4, G27, LD327, Arogya, Surabhi, MCU5 and MCU5VT were also used for the extraction of single seed globulin. The development of seed protein profile showed variability among the genotypes. In genotypes LRA 5166 and Anjali single seed proteins were extracted and separated through electrophoresis for the identification of genetic purity among the certified seed lots. The protein profile pattern obtained out of seed storage protein is used for the identification of genotypes.
• Genetic purity testing of hybrid seeds using electrophoresis technique in Cotton- The genetic purity testing of cotton hybrids and parental lines viz., Surya (HLS 329 x M 12), DHH 11 (CPD 423 x CPD 420) was conducted through profiling of seed protein globulin. The methods adopted for extraction of seed protein were 1.SDS – PAGE of salt soluble proteins, 2.SDS – PAGE of salt soluble globulins 3. SDS – PAGE of methanol ppt fraction. The method. SDS – PAGE of salt soluble proteins was found suitable. The Electrophoresis analysis for two hybrids (Suyra and DHH 11), using Salt Soluble Globulins expressed polymorphic bands of proteins. The presence of protein bands, position and intensity of bands recorded for all the samples showed greater differences and were utilized for variety characterization and identification. The protein band observed for surya (hybrid), M12 (Male parent) and HLS 329 (Female parent) are different in expression of bands. The expression of bands is nine in hybrid and eight in parents. The additional band expressed at Rm value 0.439 will facilitate for the identification of presence of female parental seeds in the hybrid (Surya) seed lot. The band expressed at Rm value 0.465 in Surya and HLS 329 confirm that the particular F1 seed would have been derived from using HLS 329 as female parent. This will facilitate the identification of other seeds particularly the male in hybrid seed lot or other cotton variety seed in hybrid seed lot. Similarly, the presence of band at Rm values 0.325 and 0.465 in CPD 423 (female) will facilitate the identification of admixtures in hybrid DHH 11.
• Effect of sowing time on production and quality of cotton hybrid seed in different zones- In seven cotton hybrids Savita (T7 X M12), Surya (T13 X M12), Sruti (70E X RSP 4), Kirti (Suman X BN), HB 224 (LRA 5166 X P4), LHH 144 (PIL 48 X PIL 8), NHH 44 (BN 1 X AC 738) it was found that sowing of parents from twentieth August to fifth September resulted in higher hybrid seed yield with enhanced boll setting %.
• 18.Film coating of cotton seeds with polymers-Film coating cotton seeds having initial viability of 90 %, with polymer polykote @ 3ml/kg of seed diluted with 5 ml water combined with carbendazim (Bavistin) @ 2 g /kg, stored in cloth bag under ambient condition prevented seed deterioration up to 18 months of storage and can retain the viability of 77%. By coating the seeds with polykote @ 3ml/kg of seed diluted with 5 ml water combined with carbendazim (Bavistin) @ 2 g /kg and Imida cloprid @ 7g /kg when seeds are stored in polythene bags, viability can be maintained to 76%
• Identification of suitable treatments for cotton seeds-A field experiment was conducted the following seed treatment to assess the seed cotton productivity. T1- No treatment (control), T2- Hydration (10 -12h) and drying at room temperature, T3-2% CaCl2 hydration at room temperature and surface drying, T4- Hydration with 50 ppm GA3 and surface drying at room temperature, T5 – Hydration (10 -12h) and drying at room temperature and dry dressing with Thiram 0.25%, T6-0.5% KNO3 hydration and drying at room temperature, T7- Seed soaking in H2O2 @ 40 mM for 6 hrs and drying at room temperature, T8- Seed soaking in KH2PO4 @ 100 ppm and drying at room temperature, T9- Seed soaking in Succinin Acid @ 0.2% before sowing and drying at room temperature, T10-2% KCl hydration at room temperature and surface drying. During the crop growth all reproductive traits were recorded. It was observed that all seed treatments have enhanced the productivity measured in terms of Plant Height, Number of Sympodia, Number of Bolls/plant and per boll Weight, however, treatments such as Hydration (10 -12h) and drying at room temperature and dry dressing with Thiram 0.25%, Seed soaking in H2O2 @ 40 mM for 6 hrs and drying at room temperature, Seed soaking in Succinin Acid @ 0.2% before sowing and drying at room temperature were more efficacious.
• Influence of pulsed magnetic seed treatment on seed cotton productivity-Seeds of twenty two cotton genotypes were subjected to pulsed magnetic seed treatment @ 5 hours for fifteen days continuously with different field strength as T 1 – Control; T 2- Field intensity(nT) 750nT, 1500nT, 500nT; T 3- Field intensity(nT) 1500nT, 500nT, 750nT; T 4- Field intensity(nT) 500nT, 750nT; T 5- Field intensity(nT) 750nT. Seed quality assessment showed significant enhancement in viability in all the genotypes especially with treatment of seed in magnetic field intensity of 750nT followed by 1500nTand 500nT. However, when the seeds are sown in the field for the estimation of the effectiveness of seed treatment in terms of seed cotton productivity, the treatment effect was non-significant, though there were numerical differences. Significant difference among genotypes was observed, irrespective of magnetic field strength for seed treatment.
• Relative performance of seed treatments on cotton seed quality enhancement and productivity- Ten halo priming seed treatment, CaCl2 hydration @2%, KH2PO4 priming @450 ppm, KCl priming @1.0% and MnSO4 seed soaking @0.1% enhanced, significantly the seed viability by 17 to 19 % and seedling vigour. Among the acids such as Boric acid @ 0.001%, ascorbic acid @300mg/lit, salicyclic acid@300mg/lit, succinic acid@0.2% used for priming cotton seeds under ambient condition, succinic acid@0.2% primed seeds recorded significantly higher viability (84%). Cotton seeds coated with eleven coating materials and it was found that among those Arappu leaf powder @ 100 g/kg and Turmeric rhizome powder @ 20g/kg increased the seed viability by 10%, seedling length and vigour. The five growth hormones used for priming the seeds such as GA3 @100 ppm, IAA@100 ppm, IBA@100 ppm, BAP@10 ppm and Zeatin@20 ppm, seed priming with GA3 @100 ppm and Zeatin@20ppm enhanced seed viability significantly by 7% and seedling length. Among the 12 botanicals and organics used for priming cotton seeds Prosopis leaf extract @1.5%, Neem leaf extract @ 1%, Dasakavya @ 2.5% and Panchakavya@10% enhanced the seed viability significantly by 10 to 13% with significant increase in seedling length. Dry seed treatments with protectants showed five to nine percent seed viability enhancement, among the eight treatments applied Thiram @ 2g/kg (5%), Bavistin @ 2g/kg (6%), Trichoderma @ 10g/kg (6%) and Turmeric rhizome powder @ 20g/kg (9%) enhanced seed viability and seedling vigour. Seeds treated with Imida chlorpid (7g/kg) alone has shown numerical increase in seed viability with significant increase on seedling vigour. The productivity of treated seeds observed in terms of field emergence, seedling growth, dry matter accumulation, number of sympodia, bolls/plant, boll weight and seed cotton yield/plant showed that priming seed treatment with CaCl2 @2%, H2O2 @ 60mM, KH2PO4@450ppm, Succinic Acid @0.2%, KCl@1.0%, Prosopis leaf extrac t@1.5%, MnSO4 @ 0.1% and Seed coating with trichoderma @10g/kg and Turmeric rhizome powder@ 20g/kg, Neem leaf extract @ 1.0%, Dasakavya @2.5%, Panchakavya @10%, Thiram @ 2g/kg, Bavistin @ 2g/kg, Trichoderma @10g/kg, MnSO4 @ 0.1%, Arappu leaf powder @ 100 g/kg, Turmeric rhizome powder @ 20g/kg, significantly increased the field emergence, seedling growth, dry matter production, boll number/plant, boll weight, seed index and seed cotton yield/plant. The fiber properties such as 2.5 span length, uniformity ratio, fiber strength, and micronaire has not been influenced due to seed treatments.
• Effect of pulsed magnetic seed treatment on aged cotton seeds-Cotton seed lots of genotypes namely Sahana, Supriya, Surabhi, JLH-168 and JCC-1 aged 12, 24 and 36 months, treated with pulsed magnetic field strength of 500 nT, 750 nT and 1500 nT for five hours a day for 15 days continuously and in combination of 500 nT (15 days), 750nT+1500nT (30 days), 500nT+750nT+1500nT (45 days) revealed that germination in 36 months stored Sahana seeds increased significantly 22%, 22% and 29% respectively, when seeds were exposed to 1500 nT, 750nT+1500nT and 500nT+750nT+1500nT pulsed magnetic field strength, over untreated seeds. In 24 months, old seeds the improvement was 17, 20 and 24%, respectively. In 12 months, old seeds this was 14, 11 and 11 % respectively. This indicates that more aged seed lots are more responsive to seed treatments that less aged seed lots. .
• Performance of PPFM seed treatment on germination enhancement under differential soil moisture- Delinted cotton seeds were primed with one percent PPFM culture formulation sown in pots filled with sand medium and soil moisture regulated from 10 to 50% for 12 days, showed an improvement in germination (71.5%) as against (57.5 %) untreated seeds at 10% soil moisture. The arithmetic increase of seed germination of primed seeds was noticed up to 35% soil moisture. Sowing primed seeds on soil moisture above 35% did not encourage seed germination. Sowing primed seeds in 15 to 25% soil moisture followed by watering once in two days also favoured seed germination. Therefore, cotton seed priming with PPFM would be useful for taking up seed sowing even when soil moisture is sub optimal provided that the same soil moisture would be maintained till the end of germination period.
• Studies to improve the seed setting efficiency in cotton- Seed setting efficiency in cotton flower differ significantly due to pollination attractants and the duration of application. Among the pollination attractants Rose extracts (10%) Dasakavya (10%) recorded higher seed setting efficiency. The interaction of Pollination attractants and varieties showed no significance; however, the duration of spray and varieties have shown significant difference. The pollination attractant had also shown significant difference for seed index and seed cotton yield. Among the seed setting treatments tried foliar application of CICR-Consortia (S) (0.1%) and NAA @40 ppm have enhanced the seed setting efficiency and seed index over control.
• DUS testing for the establishment of Distinctiveness, Uniformity and Stability was carried out for 471 new candidate varieties, 328 Variety of common Knowledge, 2 Farmers variety, 184 Essentially derived variety and 183 Initial variety.
