Presentation On Hybrid Cotton Seed Production

  1. 1. Hybrid Seed Production – Cotton Santosh Kumar Sahu Agri-Professional From Gujarat India sahubabu@gmail.com Http://www.linkedin.com/santosh4retail
  2. 2. Major Cotton Producing Country  China  India  USA  Pakistan  Uzbekistan  Turkey  Brazil  Greece  Argentina  Australia  Egypt
  3. 3. Four Species of Cotton G hirsutam G barbadense G herbaceum G arboreums
  4. 4. Cotton Seed Producers in Gujarat Tulsi,Rasi Seeds,Zuari,Mahyco,Krishidhan,Monsa nto,Ajeet,Pioneer,Vikram,Solar Agri Tech,Bioseed,Us Agri Seeds,Kaveri,Sreerama,Nath,JK,Bayer ,Kirtiman,Axis,Namdhari,Nuziveedu, Satya,Vasant Agro,Vibha,Greengold,Yashodha,NSC, and many small small companies
  5. 5. Major Cotton Producing states Punjab Haryana Rajastan Madhya Pradesh Maharashtra Gujarat AP Tamil Nadu Karnataka
  6. 6. Types of Cotton hyb seed Produced Conventional Hand Emasculation & Pollination Non Conventional ( Male Sterility based)
  7. 7. Conventional Method of Production Site Selection Isolation distance – 30 mt between crop , 5 mt between parents Fertilizer Dose – 100:50:50 NPK per ha Sowing of parents Synchronization Staggered planting Plant Protection measures
  8. 8. Conventional Method of Production Emasculation of Female parents- Generally done after 1 PM in the day Crossing of Parents – Crossing work generally starts after 1 week of flower initiation. The pollination is done on the next day between 8 AM to 11 Am can be extended upto 1 PM . Fertilization – It is done after 12-30 hours of pollination,so crossed bud should be kept in covered condition till 3-4 days.
  9. 9. Conventional Method of ProductionWhat makes the Hyb seed production successful ? Qualified Technical staff Proper trained LabourOne person can emasculate & pollinate about 250-400 flowers/day ( FAO standard)
  10. 10. Conventional Method of Production Picking is done for only the completely opened boles. Damaged,underdeveloped bolls should be separated and removed before sorting.
  11. 11. Factors that may affect in production …. The planting ratio of male & female No of flowers used in pollination from one female flower Stagerred showing patterns of the parents(proper synchronization) Stage & period of crossing Vigour of female parents Pollen production ability of the male parents Position of boll set in the plant
  12. 12. Bt cotton or Transgenic Cotton Bt gene is effective against Helicoverpa armigera Bt Direct tests gives the bt level at moleculat level Bt Quant (ELISA) tests gives the bt quantity level
