Genetic Variability Analysis in Field Pea (Pisum sativum L.)

Naveen Kumar Jaiswal | Ajeet Kumar Gupta | Hiralal Dewangan | G. Roopa Lavanya [2]

Abstract: The present experiment was conducted during November 2012 - March 2013 in the department of Genetics and Plant-Breeding to estimate variability analysis of some reproductive characters on grain yield of 12 fieldpea genotypes. The experiment was laid out in a Randomized Block Design (RBD) at the research farm, SHIATS Allahabad. The genotypes showed moderate to high level of genotypic coefficient of variability (GCV), phenotypic coefficient of variability (PCV), heritability and genetic advance were observed for days to 50 % flowering, plant height, number of pods per plant, days to maturity, number of seed per pod, pod length, 100-seed weight and grain yield per plant. The magnitudes of the phenotypic variance of these traits were higher than the genotypic variance, indicating that the phenotypic component was the major contributor to total variance. Among all traits, plant height exhibited high estimates of GCV and PCV (48.10 and 48.42) followed by seed yield per plant (24.36 and 33.69) and number of seed per pod (16.40 and 20.36). High broad-sense heritability (52.00 % - 99.00 %) indicated the presence of additive gene effects.
