Abstract:
The present investigation was undertaken to assess the genetic parameters in coriander. The thirty genotypes of coriander were evaluated under normal (E1) and limited moisture (staggered moisture regimes) (E2) conditions during rabi 2016-2017 in Randomized Block Design with three replications. The high significant differences (mean squares) due to genotypes were observed for all the characters studied in both the environment E1 and E2 as well as on pooled basis indicated sufficient genetic variability was present among the genotypes. The mean squares due to genotype x environment were also found significant for all the traits under study indicated role of environment on character expression. The moderate estimates of GCV and PCV were observed for branches per plant, umbels per plant, umbellets per umbel, seeds per umbel and seed yield per plant in both the environments. The estimates of broad sense heritability were observed to be high for all the characters in both the environments except for the traits plant height, branches per plant and umbellets per umbel in E2 environments. The genetic advance as percentage of mean was obtained high for branches per plant, umbels per plant, umbellets per umbel and seeds per umbel in E1 environments and for seeds per umbel in E2 environments. Thus, based on the present investigation it is suggested that in breeding programmes major emphasis should be given to branches per plant, umbels per plant and seeds per umbel as these characters had moderate GCV, PCV and high heritability coupled with high genetic advance as per cent of mean.
