Transgressive segregation for fibre quality

The 1329 F2, 174 B1 and 191 B2 plants were evaluated along with parents (Suvin and BCS 23-18-7) and its F1 for seed cotton yield and its component traits and fibre quality traits. Top 20 transgressive segregants were selected for seed cotton yield from all three segregation generations (F2, B1 and B2), recorded 104.02 to 169.46 per cent higher seed cotton yield than best parent BCS 23-18-7 (116.90 g/plant). Six transgressive segregants recorded 5 per cent early flowering (< 65 days) with a minimum of 50 per cent yield advantage (> 177 g) over BCS 23-18-7.

Cotton is one of the most important fiber and cash crop of India and plays a dominant role in the industrial and agricultural economy of the country. Fifty six crosses with fifteen parents and four checks viz., PKVDH 1,PKVSuvarna, NACH 12 and PA 255 were grown in Randomized Block Design with two replications during kharif, 2016 at three locations viz.,Cotton Research Station, Mahboob Baugh Farm, Parbhani (L1), Cotton Research Station, Nanded (L2), and Agricultural Research Station, Badnapur (L3).
