Abstract:

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. There were fourteen plants recorded transgressive segregation for the combination of seed cotton yield and GOT with 50 and 5 per cent advantage respectively over superior parent BCS 23-18-7. Another 14 transgressive segregants superior in combination, 3 per cent higher fibre strength (34.5 g/tex) over Suvin with 25 per cent (> 145 g) yield advantage over BCS 23-18-7.
