The two hundred recombinant inbred lines derived from cross between G. hirsutum var. DS-28 and G. barbadense var. SBYF-425 were evaluated across four testing environments at Agriculture Research Station, Dharwad during 2011-12, 2012-13 and 2013-14 and at Agriculture Research Station, Baglkot during, 2013-14. DHBR-25, DHBR-43 , DHBR-81, DHBR-161, DHBR-128 , DHBR-156 , DHBR-20, DHBR-88, DHBR-58 , DHBR-153 recorded significantly higher seed cotton yield than best parent DS-28 (853.56 kg/ha) and commercial check, Sahana (1025.63 kg/ha) accounting 21.72 to 44.72 per cent more seed cotton yield. Among these superior high yielding genotypes, three genotypes like DHBR-161, DHBR-20 and DHBR-88 recorded significantly higher fibre strength with desired level of micronaire value. The genotype DHBR-20 (1313.78 kg/ha; 24.18 g/tex) recorded significantly higher seed cotton yield with significantly higher fibre strength and on par with commercial check, Sahana (1025.63 kg/ha; 21.52 g/tex) and MCU-5 (659.49 kg/ha; 23.13 g/tex) for other traits like ginning out turn and boll weight. It indicates the possibility of simultaneous improvement for both seed cotton yield and fibre strength through interspecific hybridization.

Key words: Recombinant inbred line, Augmented design and Hybridization, Tetraploid.
