Abstract:
The present study on variability and character association studies in leafy coriander (Coriandrum sativum L.) genotypes was conducted at the Horticultural College and Research Institute, Periyakulam with the objective to estimate the extent of genotypic and phenotypic coefficient of variation, correlation and path analysis among coriander genotypes. A remarkable variability was observed among the coriander genotypes for all the characters. In all the cases, phenotypic variance was higher than the genotypic variance. Also, phenotypic coefficient of variation was found higher than genotypic coefficient of variation for all the traits. The high heritability coupled with moderate genetic advance as per cent over mean was observed in the traits such as high heritability along with moderate genetic advance as per cent over mean recorded for the characters such as number of secondary branches, number of primary branches, leaf yield per plot which might be assigned to additive gene effect governing their inheritance and these traits are more reliable for direct selection, whereas the lowest values were noticed in number of leaves per plant (4.73), days taken for germination (8.47). Thus, it indicated better scope for improvement of these traits through selection programme. Leaf yield per plot has significantly and positively correlated with plant weight (0.770), number of leaves per plant (0.766), plant height (0.749), number of secondary branches (0.519) and number of primary branches (0.315). Hence, it might be inferred that these traits could be considered as the most important yield contributing traits in coriander. Path coefficient analysis showed that yield per plot contributed the maximum positive direct effect.
