Variability and character association studies in coriander (Coriandrum sativum L.)

Abstract

Eighty germplasm lines of coriander (Coriandrum sativum L.) were evaluated in Augmented Block Design to estimate variability and character association. Analysis of variance revealed significant variability for most of the traits. Higher estimates of phenotypic coefficient of variance along with genotypic coefficient of variance as well as broad sense heritability, genetic advance and genetic advance as percentage of mean were observed for number of basal leaf, plant height up to main umbel, umbel plant-1, number of leaflets, longest basal leaf, test weight, seeds umbel-1, primary branches plant-1, plant height up to top of the plant, secondary branches plant-1, umbellate umbel-1, days to 50% flowering and seed yield. The association analysis at both genotypic and phenotypic level revealed that the seed yield plant-1 was significantly and positively correlated with secondary branches plant-1 and umbel plant-1. Associations of seed yield plant-1 with longest basal leaf, numbers of leaflets, days to stem initiation, plant height up to main umbel, umbellate umbel-1 were also positive but found non-significant.
