The present investigations involving forty five diverse pea recombinant inbreds and three standard checks were carried out for two successive years during 2011-2012 and 2012-13. The objective of the study was to ascertain genetic variability, heritability, genetic advance, correlation and path coefficient among yield and other horticultural and quality traits and identification of superior recombinants for their utilization in crop improvement programme. Wide range of variability was observed for most of the characters under study. The magnitude of phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variability (GCV) for all the traits. High phenotypic and genotypic coefficient of variations were recorded for protein content, ascorbic acid, plant height and pod yield per plant for both the years. Pod yield per plant and plant height exhibited high heritability associated with high genetic advance in the respective years indicating the additive gene action for their expression and are likely to respond better to selection. Pod yield showed a positive and significant correlation with number of pods per plant, pod length and number of seeds per pod both the years. Path analysis revealed that number of pods per plant and pod length have highest positive direct effect both the years and thus it may be treated as selection criteria for isolating higher yielding genotypes in garden peas. In heterosis study, some of the recombinant inbreds were found superior over standard checks which include L-14 and L-13 for pod yield/plant, number of pod/plant and earliness. These findings can be further utilized to develop and enhance the yield potential of garden pea.
