Estimation of genetic architecture in agro-morphological traits of garden pea in Mid Hill Region of Uttarakhand, India

Abstract

In order to appraise genetic parameters and variability in the crop, the information on the nature and degree of diversity in the genotypes is crucial. Thirty two genotypes along with two commercial varieties (PB-89 and Solan Nirog) as check were evaluated for assessing genetic variability and heritability for seventeen different agro-morphological characters. The mean sums of squares due to genotype were highly significant for all of the characters. The estimates of GCV and PCV is highest values were shown by plant height, pod yield per plant & pod yield per plots whereas moderate for dry matter content, No. of node per plant and 100 seed weight. High heritability estimates associated with high genetic gain for plant height, pod yield per plant and pod yield per plot reflecting the involvement of additive gene action suggesting more scope of selection of these traits.
