Abstract
Correlation and path analysis studies were conducted during the winter season of
2017-2018 and spring season of 2018. The present experiment was conducted to
study the availability and determines the relative importance of primary and secondary
traits in field pea, through the association among the characters viz. ( No. of pods.
plant-1 - Weight of pods. plant-1(g) – Pod length. plant-1 (cm) - No. of seeds pod-1 -
Weight of seeds pod-1 (g) - Weight of seeds. plant-1 (g) - 100 seed Weight (g) - Biological
yield. plant-1 (g) - Harvest index and Seed yield (Kg ha-1) The experimental
material comprised of 4 field pea varieties viz. (Americana, Jeza, Pakland and Avola).
From each plot, five competitive plants were selected randomly for recording observation
for all quantitative characteristics. The results were summarized as follow,
highly significant and positive association were recorded between seed yield with
other characters except for the character 100 seed weight which was not significant at
winter season and significant at spring season, but not significant with harvest index
at both seasons. The highest positive direct effect in seed yield produced by the
weight of seeds per plant at both seasons, while the highest positive indirect effect in
seed yield recorded by weight of seeds per plant via weight of pods per plant at both
seasons.
