Abstract
Field experiment was conducted at Agricultural Research Station, Dharwad farm, during 2018 and 2019 toevaluate performance of eighteen different cotton genotypes representing four different Bt events. Damage due to pink bollworm (PBW) was least in intraspecific (H×H) hybrids compared to interspecific hybrids (H×B) hybrids. Cotton hybridEverest recorded least flower damage of 9.40 per cent, followed by Jadoo (9.71%) and were on par. The highest per centflower damage of 22.57 was registered in (H × H) non Bt hybrid DCH-32. Least boll damage of 13.93 per cent was recordedin Everest BG-II and was on par with Jadoo (14.94%) and highest per cent boll damage of 41.26 was recorded in DCH-32The seed cotton yield was highest in Everest BG-II (15.20 q/ha). Among BG-I genotypes, VCH-5 (Event-1) recordedhighest yield (9.84 q/ha) and the least yield was recorded in DCH-32(5.97 q/ha).
