Correlation coefficient of different Morpho-physiological Parameters related to yield in coriander (Coriandrum sativum L.)

Eight Coriander varieties viz. Rcr-20, Rcr-41, Rcr-435, Rcr-436, Rcr-446, Rcr-475, Rcr-684 and Rcr-728 were evaluated at the research farm of S.K.N. College of Agriculture, Jobner, Jaipur (Rajasthan) during Rabi, 2016 in randomized block design with three replications on loamy sand soil. Under control condition plot were irrigated at regular interval while in drought condition plots were maintained under rainfed condition. Different physiological and biochemical parameters were recorded at flowering and seed formation stages whereas yield and yield contributing parameters were recorded at maturity stages and after harvesting. The Coriander varieties Rcr-20 and Rcr-446 behaved as drought tolerance varieties maintained higher seed yield along with number of umbels per plant, seeds per umbel, test weight, seed yield, biological yield, harvest index under drought conditions. The coriander varieties Rcr-435 and Rcr-728 maintained under higher seed yield along with number of umbels per plant, seeds per umbel, test weight, seed yield, biological yield, harvest index under control conditions.
