Abstract: Two hundred seventy five genotypes and nine checks (RCr-20, RCr-41, RCr-435, RCr-436, RCr-446, RCr-475, RCr-480, RCr-684 and RCr-728) of coriander (Coriandrumsativum L.) were evaluated in Augmented Block Design with five blocks during Rabi season of 2014-15 at Research Farm, S. K. N. College of Agriculture,Sri Karan Narendra Agriculture University, Jobnerto study the genetic variation, characters association and path analysisfor ten growth and yield characters namely, days to 50% flowering, plant height, branches per plant, umbels per plant, umbellets per umbel, seeds per umbel, days to maturity, 1000-seed weight, volatile oil content and seed yield per five plants. The association analysis at phenotypic level revealed that the seed yield per five plants was significant and positively correlated with days to maturity, test weight, umbels per plant, seed per umbel, plant height, umbellets per umbel. While, it association with volatile oil content was significant but negative. Path analysis at both genotypic and phenotypic levels indicated that the magnitude of both direct and indirect effects were generally low. Among the characters, the direct effect of plant height was found to be positive and highest indicating that the correlation of plant height with seed yield was primarily because of the direct effect.
