Open full text 1 citations

Abstract

Combining ability effects were estimated for different characters in a line × tester method comprising 21 hybrids obtained by crossing 7 lines and 3 testers. Significant differences were observed among the parents and hybrids/crosses for gca and sca respectively. Parents K27080, LC-3, C-12 and GY2 were found good general combiners for yield and its component traits. High sca effects for yield and other traits were exhibited by the cross combinations JLG × C-12, K 27080 × C-12 and K27080 × LC-3.
