Abstract:
Four females (lines) and six males (testers) were crossed in L x T mating design to obtain 24 crosses. These 24 hybrids along with 10 parents and 2 standard checks were evaluated in a randomised block design during Kharif 2021-22 at Cotton Research Station, Mahboob Baugh Farm, VNMKV, Parbhani. The data on yield and yield components were recorded viz., days to 50% flowering, plant height (cm), number of sympodia per plant, number of bolls per plant, boll weight (g), seed cotton yield per plant (g) and seed index (g). Analysis of variance carried out for the characters showed significant treatment differences for all characters studied. The magnitude of heterosis, heterobeltiosis and standard heterosis for all the characters in the present study was highly appreciable. The cross PA 863 x CNA 1032 showed highest magnitude of mid parent heterosis i.e., 34.53% and the cross PA 828 x PA 08 showed highest magnitude of better parent heterosis i.e., 22.31% for seed cotton yield per plant whereas the cross PAIG 411 x PA 740 showed highest magnitude of standard heterosis for number of balls per plant to the extent of 70.56% over standard check PKVDH 1.
