ALL INDIA COORDINATED COTTON IMPROVEMENT PROJECT - CENTERS


SURAT

Main Cotton Research station. a lead centre of AICCIP in Gujarat located at 21 0 .10'N & 72 0 48'E at Surat is one of the oldest Cotton research station in the country. Having been established in 1896, it is the hub of research policies and planning for its regional and sub station spread throughout the Gujarat state. The research efforts put in by the centre and its participating canters have contributed in release of 46 hybrids high yielding varieties and 86 agro technical recommendations. Some of the achievements of the centre have won laurels across the world. The first of which was the first Indo American variety Deviraj involving American and Asiatic blood released in 1951. Release of first intraspecific hirsutum cotton hybrid Hybrid-4 in 1994 was biggest land mark in history of cotton research. This hybrid proved to be harbinger for researchers in the country as well as in abroad. The first ever budded cotton variety G.Cot-101 was released from this centre in 1977. Desi Hybrid G.Cot.DH-7 was again another feather in the cap of this station.

The station meets the entire requirement of parent seed of hybrids for the state / private indenters as well as other states.

Achievements in last five years

Breeding

During the X th FYP, huge amount of breeding material embracing all the four species, and also hybrids both interspecific and intraspecific have been built up. The vastness of material created may be visualized from the fact that about 57 hirsutum, 44 herbaceum, 11 intra-hirsutum hybrids, 11 hirsutum-barbadense hybrids, 19 MS based hybrids, 7 desi hybrids, 14 arboreum cultures and 5 multi specific cross derivatives, totaling 167 were contributed by GAU (From 1-4-2004, NAU, AAU and JAU) for testing in different trials conducted in the Central Cotton Zone and National trial of AICCIP during the X th FYP. As a result of these trails and other state trials, three varieties / hybrids Viz., G.Cot-19, ( G.arboreum ), G.Cot-23 ( G.herbaceum ), and G.Cot.MDH-11 ((MS based desi hybrid) have been released during X th FYP period.

The intra-hirsutum hybrid GSHH-1877 (G.Cot.Hy-12) was already passed in Agresco of the university in the year 2004-2005 and it will be submitted to AICCIP annual meeting in next year for endorsement. This hybrid is having high yielding potentiality with bigger bolls, wider adoptability and suitable for rainfed condition. Having moderately tolerant to aphid, jassids, whitefly and bollworms

Further, one more hirsutum-barbadense hybrid GSHB-658 (G.Cot.Hy-102) is released / passed in Agresco, state release committee and AICCIP, annual group meeting. It has superior long staple of 34.0 mm capable of spinnig up to 60S to 80S counts which fetches higher price. Boll opening is like hirsutum type which facilitates the picking of seed cotton.

Apart from release of varieties / hybrids four intra-hirsutum hybrids viz., GSHH-2118, GSHH-2201, GSHH-1444 and GTHH-139, one hirsutum-barbadense hybrid viz., GSHB-817, two desi hybrids viz., GSGDH-6 and GSGDH-7, 17 hirsutum entries viz., GSHV-97/612, GSHV-97/13, GSHV-97/59, GSHV-99/305, GSHV-99/291, GSHV-99/307, GSHV-01/26, GSH-2, GSHV-1333, GBHV-145, GBHV-148, GBHV-153, GBHV-220, GBHV-370, GTHV0/32, GJHV-370 and GJHV-392, twelve herbaceum entries viz., GShv-384/92, GShv-1111/90, GShv-1012/90, GShv-384/92, GShv-613/97, GShv-531/92, GBhv-213, GBhv-220, GBhv-222, GBhv-229, GChv-390 and GChv-398 three arboerum strain viz., GAM-93, GAM-124 and GAM-134 were identified as promising in AICCIP, state trials and are in advanced stage of testing. The hirsutum strain GSHV-99/291 and GSHV-99/307 has reached the stage of pre-release and will be released for Gujarat state in future.

Wild germplasm

The station has also maintained a large number of G.herbaceum , G.arboreum , G.hirsutum and G.barbadense germplasm,. 22 different sterile interspecific hybrids, 19 fertile hybrids, 15 perennial cottons, 16 wild species, 56 exotic germplasm and other collections as ratoon in permanent plot.

Inter specific crosses and fertility restoration

Development of new breeding material has been taken up from existing sterile interspecific hybrids made earlier and by using wild species and perennials cottons. Various methods including back cross technique in addition the colchicine treatment has been given to the culture before crossing and polyploidy are being employed for this aspect. About 20 different sterile hybrids have been multiplied and segregating population is under study. Similarly, new interspecific crosses are also developed for incorporation of specific characters such as bollworms resistance from wild species.

Several new crosses were made amongst the segregates obtained from the material developed from interspecies crosses to combine the best economic characters i.e. yield, earliness, boll weight and good fiber characters etc. As a result of interspecies crosses in multispecies, fertile cross combination with high yield and good other economic characters were obtained. The plant progenies for specific characters were grown. Through sib mating / selection of the plant having desired characters were stabilized and are being used in crossing programme.

Male sterility in hybrid seed production

Large scale Hybrid seed production is limited because high labour cost and their inadequate supply. To cope up such problem, incorporation of male sterility in females and fertility restorer gene into male of the released and promising hybrids by back crossing programme was taken up and results are very encouraging. Some completely sterile female lines and male lines possessing fertility restorer gene have been developed in G.hirsutum . Similarly, GMS lines of G.hirsutum and G.arboreum have been procured and are being used to develop new hybrids. Some promising hybrids have been isolated and included in advance / multilocation trials. Similarly, new male sterile / restorer lines from segregating population of different hybrids developed through interspecific crosses have been identified. All these new lines are being used in development of new hybrids.

Coloured cotton

Our research on naturally coloured cotton is recent in origin and during last seven years 29 lines with various shades of khakhi and green have been identified / procured and maintained. Large scale breeding programme has resulted into identification of promising lines with high yield potentiality, stable colour and good fiber characteristics.

Breeder Seed Productions

The main centre, Surat , caters to the almost entire demand of breeder and parent seed of hybrids and stable varieties. The station produces breeder seed and parent seed and supplies to the indenting agencies through GOI and State Department of Agriculture. The production of seeds during last four years is as below:

Agronomic requirement of newly released hybrids/ varieties

Irrigated

In South Gujarat 240 kg N/ha and in South Saurashtra 160 kg N/ha with additional phosphorous was found optimum for higher yield in G.Cot. Hy-12 (GSHH-1877). Spacing of 120 x 45 cm was found best.

For cultivation of ELS hybrids G.Cot.Hy-102 in Middle Gujarat 240 kg N/ha with spacing of 120 x 45 cm was most suitable. However, in South Gujarat 160 kg N/ha was found optimum. For cultivation of G.Cot.MDH-11 (MS based desi hybrid) in South Gujarat and North Saurashtra application of 120 kg N/ha gave highest cotton yield while application of phosphorous was not found advantageous except in North Gujarat where PSB (GAU strain) application helped enhancing yield.

Promising strains GSHV-97/612, GSHV-97/13 and GJHV-337 were evaluated for their nutrient requirement. Nitrogen application @ 150 to 180 kg /ha with spacing of 120 x 30 cm was found optimum for the former two genotypes in South Gujarat . Nitrogen @ 120 kg N/ha and spacing of 90 x 30 cm gave significantly higher yield of GJHV-337 in South Saurashtra .

Rainfed

For cultivation of G.Cot.MDH-11 Nitrogen @ 80 kg/ha and 120 kg /ha was optimum in South Gujarat and North Saurashtra , respectively.

Desi variety G.Cot.-23 gave highest seed cotton yield with 80 kg N/ha and spacing of 120 x 90 cm in South Gujarat .

Integrated Nutrient Management

Reduction in Nitrogen application to 50 % with addition of 10 t FYM/ha and 2 % foliar application of urea gave highest yield of G.Cot.Hy-8 in South Saurashtra .

Different organic sources of nitrogen were tested to replace inorganic nitrogen i.e. urea. Three years experimentation concluded in 2002-03 clearly indicated that 50% nitrogen from inorganic source could be reduced and only 25% of remaining be replaced by sesamum cake or castor cake or cotton seed cake in South Gujarat

Foliar application of nutrient in cotton G.Cot.Hy-10:

Foliar application of nutrients such as KNO3, Urea did not show significant and consistent effect on yield in South Gujarat .

Entomology

1. Screening for pest tolerance : In efforts to help the breeders in identifying cotton materials with inbuilt resistance/tolerance to major insect pests of cotton, 421 entries/cultures were evaluated as many as 276, 257 and 141 entries were identified as tolerant to aphids, jassids and thrips and 23 entries /cultures were found resistant/tolerant to bollworms.

2. Population dynamics : Studies on population dynamics of different pest indicated that aphids, jassids, thrips, whitefly and spotted bollworm, Helicoverpa and pink bollworm were identified as the key pests of cotton in Gujarat . In some parts, Spodoptera incidence was high. Aphids and thrips were severe in the early stage of the crop, while jassids were prevailing throughout the crop season. Whitefly incidence was low in South Gujarat but it was severe in rest of the state. Earlier thrips was minor pest but since last five year it has emerge as a major pest and was severe during July to September.

The activity of all bollworm was observed to low to medium throughout the state. Spotted bollworms incidence was found low in the early stage of crop but it was high from October onwards in two of the four years. The activity of Helicoverpa was mostly observed from September to October, but continued up to December and. However, since last three years, the Helicoverpa incidence showed a decreasing trend. Pink bollworm incidence started from end of October till crop harvest and becomes severe during December to January almost every year throughout the state. The activity of Spodoptera was confined to September to October and in some parts it continued up to December – January. Mostly it was sporadic and occurrence occasionally.

Surveillance : Surveillance of lepidapterous pests through sex pheromanes, entries mostly confined to early stage but 'O' chaches were mostly recorded from November onwards. The traping of Helicoverpa was observed from September and continued more or less up to December. The hatches of PBW was started from October on words and its activities increased up to the end of crop period. The hatches of Spodoptera moths was observed from September and continued more or less up to the end of December.

Evaluation of new molecules : The insecticides viz. imidacloprid & 600 FS. This methoxan > OWS and 35 FS were found effective seed treatment chemicals for sucking pest management. While, the insecticides viz. imidacloprid -200 SL 350 EC, Thiomethoxam 25 EC, Acetameprid 20 SP,Thiocloprid 240 SC, Difenthuron 50 WP, Buprolezin 25 SC and Chlothinidin 50 WDG were found most effective foliar insecticides for control of sucking pests. In case of bollworms, Spinosad 45 SC, Indoxicarb 15 SC, NNI -0001 480 SC, KN-128 15 EC, Omit + Cypermethrin E-237, RIL-038 20 WDG, Lambda Cyhalothrin 5 EC, E 2 Y-45 20 SC, Karate Zion 5 CS and Spinosad 45 EC W/W A:D were found effective chemicals for control of bollworms. Emamectin Benzoate 5 SC was found to be effective IGR in reducing bollworms populations.

Integrated Pest Management : In Integrated Pest Management, different location specific IPM modules have been successfully tested in Bt and Non-Bt cotton hybrids and found beneficial for sustaining higher population of bio-agents and reducing more than 50 % pesticides consumption without reduction in seed cotton yield. The economic analysis revealed that IPM technology is beneficial with higher returns.

Pathology

  • Disease situation in the state indicated that bacterial blight prevailed throughout the state on G. hirsutum varieties/hybrids with low to moderate form (5-30 %). Gray mildew and alternaria incidence showed increasing trend (5-15%) especially with the cultivation of Bt cotton hybrids. Abiotic maladies like drying, wilting also noticed in moderate to severe form at some places.
  • Bacterial blight initiation took place between last week of July and August and progressed linearly till September end to 3 rd week of October. Except maximum temperature and rainy days no other weather parameters showed significant impact on disease development.
  • Of the 565 entries of project breeding trials evaluated for bacterial blight resistance, 77 indicated resistant reaction.
  • Bio-control agents especially Pseudomonas fluorerscens pf.l seed treatment + foliar spray were on par in their effect with streptocycline + copper oxychloride treatment against bacterial blight. Yield results were not significant.
  • Bacterial blight incidence in Bt and Non-Bt cotton hybrids was almost identical.

Plant physiology

Screening of water stress tolerant genotypes : As many as 59 genotypes / cultures sourced from different centres besides three checks were evaluated under water stress. Various parameters like Relative Water Content (RWC), Specific Leaf Weight (SLW) , Specific Leaf Area (SLA), biomass, photosynthetic area, root length and root weight etc were determined. Screening indices like Plant Height Stress Index (PHSI), Dry Matter Index (DMI), Yield Stability Index (YS) and Drought Susceptibility Ratio (S) were also computed.

The genotypes LH 1968, GSHV 97/612, F 1945, GISV-4, Indam 178, GK 147, L-761, L 763, GISV- 149, HS-267, CPD 750, NH-544, RAH-30 were found tolerant having low drought susceptibility index. SLW, SLA , RWC, root length exhibited decline under stress, but to a lesser extent in tolerant types. Other genotypes showed tolerance with low yield were FH 134, NH 545, GISV 103, GISV 185.

Management of stress through osmoprotectants : Five different chemicals (two concentration of each) were used as foliar spray with a view to ameliorate stress. Two years study indicated that KNO 3 (50%) application increased the yield under stress to the tune of 16% over control.

Modified study during 2005 -06 indicated that thiourea (500 ppm) spray was most effective in enhancing the yield to 24% over control. This was followed by KNO 3 (0.5%) + CaCl 2 (0.25%) showing 15% increase in yield. Thus by using such chemicals 15 to 20 % yield could be enhanced in stress condition.

Screening of genotypes for salinity : Four genotypes were tested at three salinity levels(EC 4, 8 and 12 dsm -1 ). Germination, seedling height, length and vigour indicated that GISV 185 and G.Cot.16 were comparatively tolerant. All the genotypes registered decline at higher salinity levels.

Physiological parameters in relation to growth and yield of cotton : Physiological parameters such as LAI, DMI, RGR, NAR, LAR, biomass, H.I. etc were evaluated at periodic interval in 31 genotypes / cultures along with checks. H-1250, GJHV 370, GSHV 99/305, L-763, H-1246 recorded higher yield than respective checks. These cultures recorded better LAI and / or better photosynthetic efficiency as indicated by NAR/RGR resulting in higher biomass. However, higher biomass is not necessarily an indicator of higher yield because of limitation in translocation (H.I.).Therefore, specific genotypes for specific trait could be used in improvement programme.

Canopy Management in Cotton : Canopy management studies for two year using different spacing and mepiquat chloride indicated that the later did help in reducing canopy but no ultimate effect on economic yield. Similarly, increasing population through inter and intra row spacing did not have any advantage in terms of yield, although canopy parameters did show differences.

Biochemistry

Biochemical base of resistance to bollworm and sucking pests of cotton: Sixty cotton genotypes were analysed for different biochemical parameters. The glands on leaves were positively correlated with phenol, tannin and gossypol content. The phenol content in leaves was found significantly positively correlated with aphids, jassids and thrips during 2003-04, while, the correlation was not significant during 2004-05 and 2005-06.

Studies on drought tolerance in cotton genotypes : Fifty nine cotton genotypes were grown under rainfed as well as irrigated condition and leaf samples analysed for different biochemical parameters such as protein, reducing sugar, total sugar, proline and nitrate reductase activity. Under rainfed condition, varieties showed high value of reducing sugar and total sugar as compared to irrigated counter parts. Greater proline accumulation was observed in rainfed as compared to irrigated condition. Nitrate reductase activity was reduced due to stress however to lesser extent in tolerant types.

Standardization of protein and isozyme banding pattern for varietal

identification : Two hybrids G.Cot Hy. -10 and G.Cot Hy. -8 along with parents was used for extraction of albumin, globuline and prolamin. G.Cot Hy. -8 recorded higher fractions of protein than G.Cot Hy. -10. This hybrid also showed negative heterosis in prolamin while G.Cot. Hy. -8 in globulin. Both hybrids showed positive heterosis in albumin fraction of protein. The protein banding pattern of different hybrids vis. G.Cot. Hy. -8, G.Cot. Hy. -10,G.Cot MDH-11 and the latest hybrid in pipeline GSHH 1877 and their parents were studied. The number of bands differed in each variety except in case of G.Cot. Hy. -10 and its female parent BC-68-2 and G.Cot MDH-11 and its male parent G.Cot 1056.

Estimation of gossypol, protein and oil in cotton seed of genotypes/hybrids : Fifty cotton genotypes were evaluated for oil, gossypol and protein content. The highest oil percentage was recorded in G.Cot Hy-8 (22.5%) followed by G.Cot Hy. -10 (20%). In comparison to hirsutum, the oil content was lower in deshi varieties. The total protein content varied significantly amongst varieties showing the maximum of 34.9 % in GSHV-99/291 followed by GSHV-97/13 (28.79%). The latest hybrid GSHH-1877 had a very high oil and protein content.

Impact of research

The giant stride made by cotton research in Gujarat are commendable. As a result of which Gujarat contributed nearly 37% from about 24% area in the national cotton production. The national productivity in the gone by year was 467 kg while Gujarat productivity was 728 kg. The average growth rate (%) in cotton productivity in the four year of X FYP is more than 8% over the average of IX FYP. The annual increase has been 32 kg/ha /year during this year.
