Abstract
The understanding of association of traits is very important in developing an efficient breeding program. The study was carried out in order to find out the genetic variation, interrelationships among different characters and the direct and indirect contributions of these characters towards yield. The germplasm of pea containing 30 genotypes were analyzed to estimate the correlations and path coefficients for yield and yield related traits. Inter-relationship of various quantitative traits like days to flowering, branches per plant, pods per plant, pod length, pod width, pod weight per plant and seed yield per plant were ascertained. Correlation studies indicated that for improvement in pea yield, the intensive selection should be made for days to flowering, pods per plant, and pod weight as these traits showed significantly positive correlation with seed yield and also among themselves. Pod length and pod width also showed positive but non significant correlation with yield so these can also be used for improvement of yield. Partitioning through path coefficient analysis revealed that number of branches per plant played an important role for the improvement of grain yield in peas.
