Study on genetic variability, heritability and genetic advance in garden pea (Pisum sativum var. hortense L.)

Abstract

In present study 25 Genotypes of garden pea were evaluated at Horticulture Research Farm, SHUATS, Prayagraj Uttar Pradesh, for eighteen parameters through genetic variability, heritability and genetic advances for yield and yield attributing Characters. Results revealed that, the maximum pod yield per plant was recorded in variety Jawahar Matar-54 followed by Variety Arkel. Heritability exerts at high degree for almost all characters studies viz pod width, shelling percentage, moisture percentage, pod yield t/hac, pod yield/plant (g), total number of leaves, total number of tendrils, days to first flowering, days to first pod set, days to 50% flowering, plant height, plant spread, average pod length, days to first pod picking, average pod weight. In the present study high heritability (bs) coupled with high genetic advances as (% of mean) were observed for the characters total number of tendrils, total number of leaves, days to first flowering, days to first pod set, days to 50% flowering, plant height, pod yield tonnes/ha, pod yield/plant (g), days to first pod picking, average pod length, average pod weight, pod width, shelling percentage. The estimation of phenotypic coefficient of variance was higher than the genotypic coefficient of variance for all traits. Therefore from the above obtained results it can be concluded that the characters will result in effective crop improvement for higher yield and yield attributing characters.
