Abstract:

Line × Tester analysis was carried out using 13 lines and 3 testers to estimate heterosis on seed yield and its contributing characters in Opium Poppy. The 39 resulting hybrids along with their parents were evaluated in Randomized Block Design during Rabi 2019-2020. The analysis of variance revealed the presence of variability among parents and crosses for the characters studied. Significant parents v/s hybrids contrast for all characters, except for days to 50 percent flowering, days to maturity and number of leaves per plant, indicated the presence of considerable amount of genetic diversity in the material tested. The experimental results for seed yield revealed that out of 39 hybrids, 15 hybrids recorded significant and positive relative heterosis, 11 and one hybrid recorded positive significant heterobeltosis and economic heterosis, respectively. The maximum heterosis and heterobeltosis was observed in cross UOP-149 × UOP-79 for seed yield per plant, harvest index, capsule husk yield per plant and number of stigmatic rays per capsule, cross UOP-68 × UOP-20 for seed yield and harvest index and cross UOP-64 × UOP-20 for seed yield per plant, latex yield per plant and harvest index for seed yield. UOP-128 × UOP-20 was the only cross which exhibited maximum heterosis, heterobeltosis and economic heterosis for seed yield in desirable direction. Thus, this cross can be recommended for exploitation of heterosis and to obtain suitable segregants.
