Abstract:
The present investigation was carried out at University of Agricultural Sciences, Dharwad during rabi seasons of two consecutive years (2021-22 and 2022-23) to screen the available twenty genotypes for drought/ moisture stress tolerance in coriander seed production. The genotypes were evaluated in strip plot design under two soil moisture regimes (well irrigated and drought induced conditions). Results indicated that the growth parameters and yield attributing characters of coriander differed significantly with respect to moisture regimes, genotypes and interaction effects and therefore, the mean seed yield per ha was significantly the highest under irrigated (8.98 q) as compared to drought condition (5.36 q). Higher yield attributes viz., umbels per plant, seeds per plant, thousand seed weight and seed yield per plant were registered by the varieties RCr-41, RCr-446, RCr-728 and RCr-435 and as a result, RCr-41 produced significantly higher yield among genotypes as well as under drought (10.69 and 8.93 q ha^-1 respectively) followed by RCr-446, (10.68 and 8.78 q ha^-1 respectively), RCr-728 (10.39 and 8.53 q ha^-1 respectively) and RCr-435 (10.37 and 8.70 q ha^-1 respectively).
