Genetic variability for pod yield and related traits in garden pea (Pisum sativum L.)
Abstract
An experiment was conducted to examine the nature of genetic variability, correlation, association of various traits with pod yield and their direct and indirect effects for effective selection in garden pea. The experimental material comprising of 41 genotypes including four checks namely, ‘Lincoln’, ‘Azad P-1’, ‘Palam Priya’ and ‘Punjab-89’ was evaluated in randomized complete block design with three replications during 2009-10 and 2010-11. Significant genetic variations was observed for pod yield and related traits. PCV and GCV were high for pods per plant and pod yield per plant. High heritability coupled with high genetic advance was observed for pods per plant and pod yield per plant. Correlation and path coefficient analysis revealed that pods per plant, pod length, seeds per pod and nodes per plant for fresh pod yield per plant could be considered as the best selection parameters for evolving high yielding genotypes.
