ABSTRACT

The preliminary results of the experiment on female to male planting ratio and staggered sowing
of male parent in DHB-290 cotton hybrid seed production conducted during 2001-02 showed shortage
of male flowers in 3:1 (female : male) planting ratio. The results of slightly modified experiment of
2002-03 indicated that the planting ratio 2:1 (female : male) and staggered sowing of 25 per cent male
one week before female, 25 per cent along with female and 25 per cent each one and two weeks later
than female was found to be optimum in order to get better synchronisation of female and male
parents by efficient utilisation of male flowers and to obtain higher hybrid seed yield with better
quality.
