Association and path co-efficient analysis among leaf yield and it’s component in coriander (Coriandrum sativum L.) genotypes

Abstract

An investigation was carried out in Horticultural College and Research Institute, Tamil Nadu Agricultural University,Coimbatore during 2015- 2016 rabi season for evaluation of Coriander (Coriandrum sativum L.) genotypes forgrowth, leaf yield and quality. The experiment was laid out in the Randomized Block Design with 30 genotypesand replicated thrice. The study revealed that the relationship of characters implied that plant weight showed asignificant positive association with the number of shoots per plant and leaf weight. Maximum significant positivegenotypic and the phenotypic correlation coefficient was significantly recorded for leaf weight and stem weightwith the number of shoots per plant respectively. Path analysis investigation on plant weight revealed that theleaf weight and the number of shoots per plant recorded very high positive direct effect on plant weight. But forthe traits, stem weight, plant height and the number of leaves registered negative direct effect.The residual effect was observed to be high. Therefore, greater emphasis should be given on these characterswhile selecting for higher leaf yield and related traits.
