6. Types of Cotton hyb seed
Produced

Conventional Hand Emasculation & Pollination

Non Conventional ( Male Sterility based)

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. 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. Conventional Method of
Production
What makes the Hyb seed production
successful ?

Qualified Technical staff

Proper trained Labour
One person can emasculate & pollinate
about 250-400 flowers/day ( FAO standard)

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. 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. 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
