Yield in chickpea is influenced by many different components including number of primary branches per plant, number of secondary branches per plant, number of pods per plant, number of seeds per pod, seed yield per plant and many other traits. All of these traits can potentially be improved through selection as long as there is sufficient genetic variation. To assess the variation for these traits, a diallel mating design was used. In the present investigation two Pantnagar released varieties viz. PG 5 and PG 170 and five ICRISAT chickpea collections viz. ICC13124, ICC14778, ICC14815, ICC16348 and ICC16349 were crossed in half diallel design and 21 crosses were generated. Observations were collected on eleven yield related traits including yield. Significant variability was observed among all the parents and crosses for all the traits except for the number of primary branches per plant. Variance components of combining ability revealed that both additive and non additive gene actions were important for yield and yield related traits. The parent ICC 13124 was the best general combiner for yield and related traits. It was also one of the parent in best specific combinations for seed yield. The cross viz. PG 170 × ICC1 6349, ICC13124 × ICC14815 and ICC 13124 × ICC 16348 were the best specific cross combinations for seed yield per plant and harvest index. This study was also useful to understand the role of additive and non additive genetic effects in determining the inheritance of different characters, for identifying good combiners, evaluating the breeding potential of population and also exploitation through adaptation of biparental approach.
