Abstract:
This investigation was undertaken to obtain information on magnitude of heterobeltiosis and standard heterosis for seed cotton yield and its component traits in interspecific hybrids of cotton. The experimental material comprised of five female parents, nine male parents and their resultant 45 hybrids developed by line × tester mating design and one standard check G. Cot. Hy. 102. The experiment was laid out in randomized complete block design with three replications at Regional Research Station, Anand Agricultural University, Anand during Kharif-2021. Among the 45 hybrids, 21 hybrids showed significantly positive heterosis over better parent and 11 hybrids showed positively significant heterosis over standard check G. Cot. Hy. 102 for seed cotton yield per plant. As per better parent heterosis, the best performing positively significant hybrids for seed cotton yield per plant were AHC-26 × ARBB-27, G. Cot-12 × GSB-43-1 and AHC-26 × DB-1502 while as per standard heterosis, the outstanding positively significant hybrids for seed cotton yield per plant were AHC-1 × DB-1502, AHC-1 × GSB-45 and AHC-26 × ARBB-27. These cross combinations can be further exploited in breeding programmes of cotton.
