Abstract:

The present study was conducted during rabi season in the year 2015-2016 at HCRI Venkataramannagudem, Andhra Pradesh. Thirty coriander (Coriandrum sativum L.) genotypes were evaluated to estimate the correlation coefficient in Randomized Complete Block Design with two replications. In the present study, GV, PV, GCV and PCV values were recorded at high range the traits fresh weight (g), dry weight (g), number of umbels per plant, harvest index (%), oil content (%) and grain yield per plant (g) indicating the existence of more variability for these traits among the genotypes. Moderate to low variability was recorded for plant height, number of primary branches per plant, number of secondary branches per plant, number of leaves, leaf area, days taken to 50% flowering, number of umbellets per umbel, umbel diameter, number of schizocarps per umbel, number of schizocarps per plant, days taken to maturity, herbage yield (g) and thousand seed weight (g) since they had moderate to low GCV and PCV values. High heritability coupled with high genetic advance as per cent of mean indicates the operation of additive gene action as observed in case of number of primary branches per plant, fresh weight (g), dry weight (g), number of umbels per plant, number of schizocarps per umbel, number of schizocarps per plant, herbage yield (g), harvest index (%), oil content (%) and grain yield per plant (g). Hence, direct selection based on these traits in genetically diverse material could be effective for desired improvement. Moderate genetic advance as per cent of mean with high or moderate heritability indicates the action of both additive and non-additive genes as computed in case of plant height, number of secondary branches per plant, number of leaves, leaf area, days taken to 50% flowering, number of umbellets per umbel, umbel diameter (cm), days taken to maturity and thousand seed weight (g) and therefore selection based on these traits may not be of great advantage.
