Abstract

The present study was carried out in 184 F2 progenies derived Him Palam Matar-1 × L-40-1014 following augmented block design in four blocks with five check varieties, replicated in each block. Analysis of variance revealed significant differences for all morpho-physiological traits. High PCV and GCV vis-à-vis high heritability and genetic advance were observed for primary branches/plant, peduncle length, stipule width and pods/plant indicating the predominance of additive gene action. Correlation studies showed positive association of pods/plant with stipule length, leaf length, leaf width, seeds/pod, nodes/plant, internodal length, plant height, pod length and pod width, signifies their importance in selection process. F2 progenies namely, P-49, P-125, P-34, and P-84 were the most diverse along with P-1, P-23, P-29, P-40, P-67, P-115, P-98, P-63 and P- 35 based on PCA and yield attributes, and needs focus to identify superior progenies in segregating generations which will help to strengthen garden pea germplasm.
