Evaluation of yield contributing traits in coriander (Coriandrum sativum L.) varieties under drought conditions

Coriander (Coriandrum sativum L.) also called ‘Dhania’ (Hindi), belongs to Apiaceae family is an important seed spice, tall herbaceous annual diploid (2n=22) crop grown around the world for its fruits as well as for tender green leaves.

The present investigation was done to assess the genetic variations among coriander genotypes for drought stress. Eight Coriander varieties viz. Rcr-20, Rcr-41, Rcr-435, Rcr-436, Rcr-446, Rcr-475, Rcr-684 and Rcr-728 were evaluated in randomized block design with three replications at the research farm of S.K.N. College of Agriculture, Jobner (Rajasthan) during Rabi, 2016. The plot was irrigated at regular interval in control condition while in drought condition plots were maintained under rainfed condition. The various morpho-physiological or yield and yield contributing parameters were recorded at maturity stages and after harvesting. The mean performance of the genotypes was decreased under drought stress in comparison to control condition for all parameters.

The coriander varieties Rcr-446 and Rcr-20 were found to be drought tolerant varieties with less effect of water stress on yield contributing traits. While, coriander varieties Rcr-435 and Rcr-728 maintained higher seed yield along with number of umbels per plant, seeds per umbel, test weight, seed yield, biological yield, harvest index under control conditions. Thus, these varieties may be used as drought tolerant varieties for further investigation.
