Abstract

Correlation and path coefficient analysis was carried out using 40 diverse genotypes of napier grass for 10 component characters including green fodder yield. Number of tillers per plant. number of leaves per plant, leaf weight, stem weight and leaf stem ratio had positive correlation with greza fodder yield both at phenotypic and genotypic levels. Path analysis showed positive direct effects of leaf weight, stem weight, leaf stem ratio, number of tillers per plant on green fodder yield. These traits should be given more emphasis while selecting for improvement in green fodder yield.

Keywords: Napier grass, correlation, path analysis
