Abstract

The present investigation was undertaken to study combining ability for yield and yield components in chickpea (Cicer arietinum L.). Of the seven parents in this study, P–9624 and ICP–71 were good combiners for yield per se and also for most of the yield characters. It is evident from the results of g.c.a. and s.c.a. effects that seed yield is largely dependent upon pod number and 100-seed weight. General combining ability variances were higher than s.c.a. variances for plant height, flowering time, pod number and 100-seed weight. Simple breeding procedure involving selection based on progeny performance, which is expected to mop up additive variances effectively, has been suggested for improving these traits. For branch number and yield per se s.c.a. variances were more important indicating the predominance of non-additive genetic variances in the inheritance of these characters. Therefore, genetic advance for branch number and yield per se will be difficult by simple selection. Recurrent selection can be effectively used for making improvement in these two characters. It is further concluded that simple selection by progeny testing and recurrent selection should be used to evolve high yielding lines in this crop.
