Research article CORRELATION COEFFICIENT AND PATH ANALYSIS IN CORIANDER (CORIANDRUM

ABSTRACT: Twenty-five coriander (Coriandrum sativum L.) genotypes were evaluated to estimate the correlation coefficient and path analysis in Randomized Complete Block Design with three replications. Seed yield per plant exhibited positive and significant correlation with plant height, plant spread, fresh and dry weight of plant, days to 50 per cent flowering, number of umbels per plant, number of seeds per umbellet, days to seed maturity and harvest index. The perusal of path analysis revealed that the traits viz., dry weight of plant and harvest index had higher direct and positive contribution towards seed yield. Therefore, great emphasis should be given for aforesaid characters while selecting for growth and yield related traits. Key words: correlation coefficient, path analysis, coriander genotypes
