Abstract:

Half diallel analysis of ten parents was performed to know the high heterotic crosses and their relationship in terms of general and specific combining ability (GCA & SCA) in Indian mustard. The relative heterosis and heterobeltiosis were observed to be the highest with respect to siliquae on main shoot in crosses BPR-549-9 × UP-II-73 and Urvashi × NRCHB-101, siliquae length in crosses UP-II-73 × NRCHB-101, UP-II-73 × Rohini and NRCHB-101 × Rohini, main shoot length in cross UP-II-73 × NRCHB-101, fruiting zone length in cross NRCHB-101 × Rohini, primary branches per plant in case of cross BPR-543-2 × Urvashi  and secondary branches per plant in case of cross BPR-549-9 × EC-511664.GCA and SCA variances were significant in most of the characters. The variance of GCA (σ2g) was observed to be higher for siliquae per plant, fruiting zone length and main shoot length whereas the variance of SCA (σ2s) was higher for main shoot length and other remaining characters.
