Studies on Genetic Variability, Character Association among Yield

Coriander (Coriandrum sativum L.) leaves constitute one of the richest sources of vitamin C (125-250 mg/100 g) and vitamin A (5200 IU/100 g). A pleasant aromatic odour is present in the stem, leaves and fruits of coriander and it is due to presence of -linalool. Analysis of variance were estimated significant for plant height (30, 60, 90 days), days to 50% flowering, number of seeds per umbel, seed yield per hectare, seed yield per plant, test weight. The highest estimates of GCV along with PCV were found for number of seeds per umbel, seed yield per plant, number of umbellets per umbel. The estimate of heritability was found very high for seed yield per hectare. The genetic advance was recorded highest for number of seeds per umbel, seed yield per plant and seed yield per hectare. Genotypic and phenotypic level revealed that the seed yield was highly significantly and positively correlated with number of umbellets per umbel, number of umbels per plant, number of primary and secondary branches, number of seeds per umbel. Path coefficient analysis of different characters contributing towards seed yield per plant showed that seed yield per hectare had highest positive direct effect.
