Path analysis for yield and its attributes in garden pea (Pisum sativum L. sub sp. hortense Asch and Graebn)

摘要

Thirty genotypes of garden pea were studied for genotypic and phenotypic correlations and path-coefficient analysis. Pod yield per plant had a strong and positive correlation with seed yield per plant, number of pods per plant and length of pod. Path-coefficient analysis at genotypic level revealed that days to 50% flowering, number of pods per plant, length of pod and plant height had a high positive direct effect on pod yield. Therefore, a selection index comprising of the characters like days to 50% flowering, number of pods per plant, length of pod, plant height and seed yield per plant can-be considered highly dependable and reliable characters for selection to improve green pod yield in garden pea.
