摘要

Combining ability analysis was carried out using line x tester design. Six lines and nine testers were crossed and 54 hybrids were developed during Kharif2006 to study seed cotton yield and fibre quality parameters. The parents, hybrids and three checks viz., PHH.316, NHH.44 and Bunny were planted in Kharif 2007 at different locations. Observations recorded on 14 yield and yield contributing characters with an objective to estimate combining ability. The estimates of gca effects revealed that the parents PH.348, PH. 1009, PH. 1024 and PH.297-7-1 were found best general combiner not only for seed cotton yield per plant but also for other yield contributing characters in desired directions, in respect of specific combining ability the hybrids KH.121xPH.l024, KH.120x NH545, KH.121x PH. 348 and PH.297-7-1 x PH. 1024 had shown positive significant sea effects for seed cotton yield and its component traits.
