GENETIC ADVANCE AND HERITABILITY FOR YIELD AND DIFFERENT ATTRIBUTES IN CORIANDER (CORIANDRUM SATIVUM L.) IN HIGH HILL REGIONS OF UTTARAKHAND, INDIAJaidev Chauhan, Manuj Awasthi, Vijay Kant Purohit and Ajaya Palliwal
Huge amount of variability in the germplasm provides better chance of selection in desired genotypes. Hence knowledge of the significance and type of variability existing in the germplasm for yield and its attributing traits is an important pre-requisite to carry out any crop improvement programme. In the present study twenty four coriander (Coriandrum sativum L.) genotypes were evaluated to estimate the variability studies in Randomized Complete Block Design with three (03) replications. Evaluation for different horticultural traits Pali LC, KP Local, Pant Haritma, Dhulet Local, Siku LC and Pant LC recorded highest fruits per umbel and also gave better yields for other horticultural traits like seed yield per plot (g) than check cultivar HL Normal. Genetic analysis indicated that Phenotypic Coefficient of Variation (PCV) was higher than Genotypic coefficient of variation (GCV) in all of the attributes studied. The selection for the characters like plant height (cm), seed yield per plot (g) can be performed to achieve improvement. The Phenotypic Coefficient (PC) and Genetic Coefficient (GC) were found high for almost all the traits except maturity duration, days to 50% flowering and days to first umbel unfolding, test weight (g) and number of primary branches per plant and plant height (cm). Environment and its interaction with the genotypes were observed to be significant for all the traits in the present study.
