STUDIES ON CHARACTER ASSOCIATION AND PATH COEFFICIENT ANALYSIS FOR YIELD AND YIELD RELATED TRAITS IN GREENGRAM [VIGNA RADIATA (L.) WILCZEK]AMAN MISHRA, SHWETA, TARUN RATHORE AND ABHISHEK PATI TIWARIAbstract Genetic association and path coefficient analysis were studied at phenotypic and genotypic levels in 19 genotypes of greengram for various quantitative characters during kharif 2022. The experimental design which was used to conduct the experiment was a randomized block design. Analysis of variance revealed highly significant differences among the genotypes for all the characters under study indicating the presence of adequate variability among the varieties. Estimates of phenotypic coefficient of variation (PCV) were higher than genotypic coefficient of variation (GCV) for all characters. High heritability was observed with high genetic advance as mean percentage by 100 seed weight, biological yield and harvest index. Number of clusters per plant, number of pods per plant, number of seeds per pod, 100 seed weight, harvest index and seed protein content showed significant and positive phenotypic correlations in seed yield per plant. Specific seed yield per plant showed significant and positive genotypic correlation with number of clusters per plant, number of pods per plant, number of seeds per pod, 100 seed weight, harvest index and seed protein content. High magnitude of positive direct effect at phenotypic level on grain yield per plant was shown by number of clusters per plant, number of pods per plant, pod length, number of seeds per pod, 100 seed weight, biological yield, harvest index and seed protein. High intensity of positive direct effect at genotypic level on seed yield per plant, number of clusters per plant, harvest index, biological yield, plant height and number of pods per plant was applied by material. |
