Association studies in coriander (Coriandrum sativum L.) under irrigated and limited irrigation conditions

Field experiment was conducted by using 25 diverse genotypes of coriander during the rabi seasons of 2012–13 at Instructional Farm, Junagadh Agricultural University, Junagadh. Seed yield per plant showed significant and positive correlation with umbels per plant, harvest index, seeds per umbel, longest basal leaf length, umbellets per umbel, number of fruit bearing branches, plant height and 100-seed weight in irrigated conditions, whereas with harvest index, umbels per plant, number of fruit bearing branches and number of umbellets per umbel, under limited irrigation conditions. Path analysis revealed that the maximum direct and positive effect was due to umbels per plant, number of fruit bearing branches, seeds per umbel, harvest index, plant height, days to maturity and longest basal leaf length under irrigated condition, whereas days to 50% flowering, number of fruit bearing branches, umbellets per umbel, plant height, harvest index and longest basal leaf length in limited irrigation conditions.
