Estimation of heterosis and combining ability for oil and protein content in soybean [Glycine max (L.) Merrill]

Abstract

The analysed the heterosis and combining ability for protein content ant oil content in soybean. 21 F1 hybrids were developed from crosses between seven line and three tester of soybean in line x tester mating design. These 21 crosses along with parent including check JS 95-60 were evaluated in Randomized Block design with three replications. In present study on mean performance, heterosis and combining ability, crosses viz., RKS 18 x JS 20-98, RVS 2011-10 x NRC 150, RVS 2011-10 x NRC 130 and AUKS 238 x JS 20-98 were identified for quality traits. The results of present study suggested that heterosis coupled with high SCA effects might be considered as a criteria for selecting crosses for further improvement with respect to quality traits.
