Analysis of variance revealed highly significant genotypic differences for all the characters under study. Wide range of variation was observed among the plants of six different ecotypes for various morphological yield and yield attributing traits. Phenotypic coefficient of variation for all the traits was higher than the genotypic coefficient of variation, indicating that all these characters had interacted with the environment. Moderate coefficient of variation (genotypic and phenotypic) was observed for number of seeds umbel-1 and seed yield plant-1 indicating fair amount of variability present for the traits under mention. Heritability (broad sense) was high for number of umbels plant-1; number of umblets plant-1 in primary, secondary and tertiary umbels; number of seeds umbel-1 in primary, secondary and tertiary umbels; seed yield m-2and 1000-seed weight which indicated that these characters could be improved through selection.
Key words: Characterization, black caraway morphological traits, yield and yield attributing traits
