Association analysis in coriander
Two hundred genotypes of Coriandrum sativum exhibited genetic variability for plant height, primary and effective branches, days to flowering and maturity, umbels and umbellets per plant, grains perumbellet, thousand seed weight, straw yield and grain yield per plant and harvest index. Heritability estimates were high for days to flowering, 1000-grain weight and days to maturity; moderate for plant height, straw yield, umbels and umbellets and number of primary branches; and low for harvest index, effective branches, grain yield, and grains per umbellet. Genotypic correlations of grain yield per plant were moderate with umbellets per plant, umbels per plant, number of effective branches, straw yield per plant, number of primary branches and plant height. Maximum direct contribution to grain yield per plant was made by umbellets per plant, followed by straw yield per plant, umbels per plant and grains per umbellet. Umbellets per plant made sizeable indirect effect via straw yield per plant. Straw yield per plant made sizeable indirect contribution via umbellets per plant.
