 ABSTRACT

A study was conducted  to evaluate germination percentage of hybrids derived from diverse CMS sources in sunflower.  The seeds sampled for germination test showed significant variation at immediately after harvest, 15 DAH, 30 DAH and 45 DAH period. Immediately after harvest, higher (8.07 %) germination per cent was found in the cross CMS335A × RHA95C1 and lower (4.11 %) in IMS850A × NS8. Whereas at 15 DAH, 30 DAH and 45 DAH the higher (22.33 %,64.00 % and 92.33 %,respectively) germination was recorded in FMS852A × RHA6D1 followed by (19.00 %, 63.67 % and 91.67 %, respectively) in CMS851A × NS15 and lower (4.95 %, 14.33 %, 53.00 % and 83.67 %,respectively) germination was recorded in FMS407A × RHA95C1. But at 60 DAH, there was no significant variation between hybrids, as all the hybrids varied between 98 to 100 per cent germination due to complete removal of dormancy.
