Abstract

A 6x6 diallel experiment was conducted on brown mustard Brassica juncea.L to determine combining ability analysis for yield and its components during 2000-2002 at the Faculty of Agriculture, Gomal University Dera Ismail Khan. Estimates of variance due to general combining ability (GCA), specific combining ability (SCA) and reciprocal effects were highly significant for all characters except the variances due to reciprocal effect for the number of primary branches, length of main inflorescence and specific combining ability effect for seed yield plant -1 which were found to be non significant. Higher magnitude of mean squares for general combining ability effects as compared to specific combining ability were recorded for all the characters and thus all the parameters were governed by additive type of gene action. B.L 9141 and 9142 were found to be the best general combiners for all the characters studied. The good general combiners for all the traits formed superior specific and reciprocal combinations with R. L- 18 and Early raya for all the characters and is therefore recommended for inclusion in the breeding programs for the evolution of high yielding Brown mustard varieties.
