Abstract:
Ninety genotypes were assessed with four check varieties of field pea to identify elite genotypes for certain quantitative traits. For the fulfillment of this, data on various quantitative characters were recorded on the basis of mean values of recorded data such as genetic variability, character association, path coefficient, mean performance of the genotypes and genetic divergence analysis were done in Augmented Block Design. Through the analysis of genetic variance it was found that moderate to high level of genetic variability were exhibited by all the genotypes for almost all the characters except pod length. Higher GCV were recorded for pod length (22.84), number of pods per plant (20.96), for these characters PCV were 25.30 and 21.02, respectively, indicated that the effects of environment on the expression of the characters was quite meager. Correlation analysis indicated that the pods per plant had highly significant and positive correlation with seed yield per plant followed by number of branches per plant. Path analysis indicated that biological yield per plant, harvest index and number of pods per plant has higher direct as well as indirect effects on seed yield per plant. On the basis of non-hierarchical Euclidean cluster analysis, all the genotypes were grouped into ten distinct non-overlapping clusters in which cluster number IV and X were found largest having twelve genotypes while cluster IX had lowest (2) number of genotypes e.g., Pant Pea 223 and NDP 14-11. The highest intra cluster distance was observed within cluster IV (12.79) followed by cluster III (12.00). The maximum (84.87) inter cluster distance was recorded between cluster II and VIII and between cluster II and cluster V (75.30), indicated that promising segregants could be obtained through mating between the genotypes of these clusters.
