Heritability And Correlation Coefficient Analysis For Fruit Yield And Its Components In Coriander (Coriandrum Sativum L.)

The objectives of this study were to estimate the phenotypic and genotypic coefficients of variation, broad sense heritability, genetic gain and correlations in coriander (Coriandrum sativum L.). The experiment was laid out in a randomized complete block design with three replications in the Institute of Agriculture, Karnobat, Bulgaria during a three-year period (2011–2013) and involved 9 coriander genotypes. Genotypes differed significantly at (p>0.001) for all the traits studied. Genotypic coefficients of variation were lower than the corresponding phenotypic coefficients in all the traits studied, indicating considerable influence of the environment on the expression of the traits. High broad sense heritability estimates ranged from 55,88 % for fruit weight per umbel to 94,41 % for number of primary branches per plant, while fruit yield showed 82,80 % heritability. High heritability and genetic advance were recorded for the number of umbels per plant. Fruit yield exhibited significantly positive correlation with the number of umbels per plant (r = 0,858) and fruit weight per plant (r =0,789). Therefore, the results suggest that the number of umbels per plant may be considered as important characters in breeding programs aiming to coriander yield improvement
