ESTIMATION OF GENETIC VARIABILITY IN PEA (PISUM SATIVUM L.)

Abstract

Genetic variability estimation was conducted in twelve genotypes of peas during growing season 2011-12. Analysis of variance was highly significant for all characters studied except plant height present high scope for selection. The highest genotypic and phenotypic co-efficient of variation were recorded for pod per plant (31.62, 31.99) followed by seed yield per plant (22.87, 23.65), cluster per plant (18.81, 20.21) and lowest was noted for days to maturity (1.88, 2.15). High heritability with high genetic advance as percent of means was recorded for pod per plant (0.98, 64.37%) followed by seed yield (0.94, 45.56%). The lowest was observed for plant height (0.35, 13.80%). The study indicates that emphasis should be given to these characters for yield improvement.
