Abstract: Twelve Bt cotton genotypes <em>viz</em>., Jai, Akka, Tulasi 9, Viswanath, Mallika, Durga, Bunny, Tulasi 118, MRC 7347, MRC 7201, Chiruta and MRC 7351 were evaluated for fibre quality and its components character with the objective to identify superior Bt hybrids for irrigated condition at Tamil Nadu Agricultural University. Ginning outturn ranged from 31.6- 38.3 per cent, 2.5 per cent span length ranged from long to extra-long (31.8 mm – 35.6mm). Fibre strength ranged from low 21.0 -23.9g/tex^-1 strong. Whereas micronaire values ranged from fine 21.0 to 6.54 very coarse. Considering, ginning outturn and fibre quality parameters hybrids namely Akka Bt, Mallika Bt and Chiruta were found promising.
