Study of correlation and path analysis for green pod yield and its contributing traits in vegetable pea (Pisum sativum L.) genotypes

This study aimed to investigate the correlation and path analysis of green pod yield and its contributing traits in vegetable pea (Pisum sativum L.) genotypes. The experiment was carried out at the Vegetable Research Farm, Department of Horticulture, Birsa Agricultural University, Kanke, Ranchi during Rabi 2021-22 in the experimental design Randomized Block Design (RBD) with three replications, using twenty-one genotypes of vegetable pea (Pisum sativum L.). Observations were recorded under growth, yield attributing characters and qualitative parameters. Analysis for yield attributing characters were carried out for all the traits which are directly or indirectly associated with the yield and yield contributing traits. Phenotypic variance was higher than genotypic variance for all the traits and similar trend was followed for PCV and GCV. This suggest that selection of these trait may be effective as heritability is most likely due to additive gene effects. Correlation studies revealed that positive genotypic significant correlation was observed for green pod yield per plot and TSS % with green pod yield per hectare. Positive phenotypic correlation was observed with plant population at last harvest, survival %, 100 seed weight and number of green pods per plant, number of seed per pod, shelling % and green pod yield per plot. Path coefficients were calculated at phenotypic levels for all the yield attributing traits. Therefore, the study provides valuable insights for breeders aiming to enhance yield potential in pea genotypes through trait-based selection strategies.
