CHARACTER ASSOCIATION AND PATH ANALYSIS FOR SEED YIELD AND ITS COMPONENTS IN GRASS PEA (Lathyrus sativus L.)

Abstract

Present Experiment was conducted on Twentyone genotypes and these were evaluated during 2016-17 and 2017- 18.the observations were recorded on different quantitative traits to estimate variability, heritability and genetic advance as % mean, character association and path analysis. In this study we find that High heritability with high genetic advance as % mean was observed for seed yield and number of pod plant -1 which reveals simple selection is effective to develop these characters. Correlation studies revealed that seed yield plant -1 showed the highly significant positive correlation at genotypic level with the traits viz., Days to 100% flowering, Days to 50% Pod maturity, Number of primary branches, Number of secondary branches, Number of seed Pod -1 and Days to harvesting. The study of path analysis indicated that, at genotypic level. High positive direct effect towards seed yield was exhibited due to number of seeds pod -1 followed by number pod plant -1 , number of secondary branches, days to 100% flowering, days to 50% pod maturity and days to harvesting. Therefore direct selection for these characters will help in development of high yielding varieties of grass pea.
