Abstract

The experiment was undertaken on nine genotypes namely 2007, 8918, 2002, 9903, 9106, 9807, 2015, 2108 (germplasm lines) including check variety Azad Dhania-1 of coriander (Coriandrum sativum L.). The materials were evaluated in an augmented Randomized Block Design with three replications during the rabi season of 2009–10. Efforts have been made to study the association of component traits with seed yield. It came into account that seed yield was significantly and positively correlated with its component characters like the number of primary branches plant−1 (rg = 0.750** and rp = 0.581**), number of secondary branches plant−1 (rg = 0.471* and rp = 0.431*), number of umbels plant−1 (rg = 0.932** and rp = 0.801**), number of umbellets plant−1 (rg = 0.806** and rp = 573**), number of seeds umbel−1 (rg = 667** and rp = 0.569**) and umbel diameter (rg = 851** and rp = 0.703**) both at the genotypic and phenotypic levels. Thus, the data revealed that the highest positive correlation (0.932) was appeared between number of umbels plant−1 and seeds yield (gm) whereas the lowest positive correlation (0.031) was expressed between number of umbellets plant−1 and 1000-seeds weight. Hence, the study will help the breeder to know the degree of association between traits, which can be used for crop improvement through selection of component traits.
