Variation and Character Associations of Grain Yield and its Component Characters in Coriander

A collection of 200 lines of coriander (Coriandrum sativum L.) showed significant variability for plant height, branches/plant, days to flowering and maturity, umbels and umbellets/plant, grains/umbel let, 1000-grain weight, straw and grain yield/plant. The heritability estimate was high for 1000-grain weight, days to flowering and maturity, and low for umbels, umbellets, and grain yield/plant. Grain yield/plant had positive and significant correlation with plant height, branches, umbels, and umbellets/plant, grains/umbel let, and straw yield/plant. Path coefficient analysis revealed that umbellets/plant. 1000-grain weight, and branches/plant were the most important characters for selection of high yielding genotypes, as they had direct positive effect as well as positive (except 1000-grain weight) association with grain yield/plant.
