Abstract: Field experiment was conducted at Agricultural Research Station, Dharwad farm, Dharwad during 2018-19 and 2019-20 to evaluate performance of eighteen different cotton genotypes representing four different Bt events. Damage due to pink boll worm (PBW) was least in interspecific (H×H) hybrids compared to interspecific hybrids (H×B) hybrids. Cotton Hybrid Everest recorded least square damage, flower damage, green boll and locule damage followed By Jadoo in both the seasons. Highest number of GOB/plant 26.68/pl and 25.89/pl observed in interspecific (H×H) hybrid Everest during 2018-19 and 2019-20, respectively, followed by Jadoo (25.61/pl in 2018-19 and 24.45/pl in 2019-20). Further, Everest recorded highest kapas yield of 15.88 q/ha and 14.52 q/ha followed Jadoo which recorded 14.90 and 13.68 q/ha of kapas yield during 2018-19 and 2019-20, respectively.
