Correlation analysis on different characters in garden pea (Pisum sativum var hortense L.)

Abstract

A field investigation was carried out at experimental farm of Department of Vegetable Science, College of Horticulture, Mandsaur (MP) to estimate the character association for 17 quantitative traits in 20 diverse genotypes of garden pea during the year 2018-19. The correlation studies revealed that pod yield per hectare exhibited highly significant and positive correlation with pod yield (g/plant), pod yield (q/ha), average pod weight (g), total sugar, T.S.S., number of seeds per pod, protein content, number of leaves per plant, number of pods per plant, pod length (cm), shelling percent, Plant height, number of primary branch per plant and negative association with days to first flower appearance, days to 50% flowering and days to first picking and phenotypic correlation coefficient revealed that the pod yield per hectare showed the maximum significant positive correlation with pod yield (g/plant), pod yield (q/ha), average pod weight (g), total sugar, T.S.S., number of seeds per pod, protein content, number of leaves per plant, number of pods per plant, pod length (cm), shelling percent, Plant height and number of primary branch per plant. Negative association showed with days to first flower appearance, days to 50% flowering and days to first picking.
