Studies of genetic variability, heritability and genetic advance for yield contributing traits in field pea (Pisum sativum L.)

Abstract

Twenty-nine diverse genotypes of field pea were evaluated at agricultural research farm Nidharia of S.M.M. Town Post Graduate College, Ballia during Rabi 2015-2016 in a randomized block design (RBD) with three replication to study of genetic variability, heritability, genetic advance. The data was recorded on five randomly selected plants for nine characters. Analysis of variance (ANOVA) express significant for all characters. The highest mean value was observed for test weight (149.46) followed by days to maturity (97.35) and plant height (82.92). The estimates of phenotypic coefficients of variation (PCV) were slightly higher than genotypic coefficients of variation (GCV) for maximum traits. Highest genotypic coefficient of variance (GCV) and phenotypic coefficient of variance was recorded for number of pods per plant followed by number of seeds per plant. High heritability coupled with high genetic advance for plant height (99.50), seed yield per plant (98.60), number of pods per plant (98.10) and number of seeds per plant (97.20). The results revealed that these traits may serve as effective selection attribute during selection in breeding program for yield improvement in wheat.
