A field experiment was conducted in black cotton soils with seven Bt.cotton hybrids viz., Santhi, Bhakthi BG II, Bunny BG II, Dr. Brent BG II, RCH 2BG II, First class BG II and Jadoo BG II and were replicated thrice in Randamised block design in farmer’s field at Ammanabrolu village of Prakasam district during kharif, 2014. The experimental soil was moderately alkaline (pH: 8.6) and saline (ECe: 8.8 dSm-1) in nature, available nitrogen 272 kg ha-1, phosphorous 27 kg ha-1 and potassium 341 kgha-1. Among the hybrids, First class Bt. cotton recorded significantly highest kapas yield (2244 kg ha-1) followed by  Dr.Brent Bt.cotton (2239 kg ha-1) and Jadoo Bt.cotton (1992 kg ha-1) . Significantly  highest boll weight was recorded in Bhakti Bt. cotton (5.36 g) followed by first class Bt. cotton (5.16 g) and Jaddu Bt. cotton (5.10 g). The highest lint index (6.37 g) and ginning out turn (41.62 %) was recorded in Dr. Brent Bt. Cotton followed by Bhakti Bt. The significantly highest span length (30.41 mm) and bundle strength (23.32 g tex-1) of fibre were recorded in First class Bt. followed by Jadoo Bt. and Bunny Bt.

Keywords:  Bt. cotton, salt tolerance, yield, fibre properties etc.
