dc.description.abstractThe experimental material comprising of fifteen F1s generated by crossing six diverse lines of field pea (Pisum sativum var. arvense) in a half diallel fashion and their six parents were evaluated in Randomized Complete Block Design with 3 replications at SKUAST-K, Shalimar campus, Srinagar during rabi, 2004-05. Observations on various quantitative traits were recorded and the data subjected to diallel analysis of Griffing (1956) and Hayman (1954a,b). The estimates of genetic components of variance revealed significance of both additive and non-additive gene action for plant height, primary branches plant-1, 100-seed weight and harvest index whereas, there was preponderance of non-additive gene action for other traits studied. Non-additive genetic variances were relatively greater than corresponding estimates of additive component of variance. The analysis of various proportions of genetic components revealed that average degree of dominance was in the range of overdominance for all traits except plant height where dominance was complete. There was assymetrical distribution of positive and negative alleles in parents with preponderance of dominant alleles. The heritability estimates were moderate for all the traits. None of the parents/crosses was found to be good general/specific combiner for all traits. The parents FP2-80, FP2-82 and Rachna were found to be good general combiners for most of the traits. The best crosses for most of the important traits were FP2-80 x Rachna, FP2-60 x Rachna and FP2-60 x VL-1. Recurrent selection is suggested as an effective procedure for exploitation of both additive and non-additive gene action bringing about sizeable improvement in population performance and simultaneously maintaining adequate variation in the population. Moreover, due to lower heritability values, indirect selection using component breeding can be a suitable approach for seeking improvement in grain yield of pea.en_US
