Genetic variability studies in pea (Pisum sativum L.)

Abstract

The present investigation was carried out to estimate phenotypic and genotypic coefficient of variation, heritability (broad sense) and genetic advance per cent of mean for 14 quantitative traits in 21 different genotypes of pea during Rabi 2017-18 at Instructional-Cum-Research Farm, Department of Horticulture, College of Agriculture Latur, Vasantrao Nike Marathwada Krishi Vidyapeeth (M.S.). Significant differences among the genotypes were observed for all the characters under study. The PCV and GCV values were high for number of primary branches per plant, green pod yield per hectare, green pod yield per plot, green pod yield per plant, pod length, number of seeds per green pod and number of pods per cluster. High heritability and high genetic advance were observed for characters like plant height, number of primary branches per plant, days to initiation of first flowering, days to 50% flowering, days to first picking, number of pickings, number of clusters per plant, number of pods per cluster, pod length, number of seeds per green pod, green pod yield per plant, green pod yield per plot and green pod yield per hectare.
