Abstract
This research was conducted in kharif during 2017 at research farm of SVPUA&T, Meerut, U.P. India. Total 30 genotypes were grown with recommended plant spacing and its collected from different agriculture universities of India. The studies of genotypic and phenotypic correlation coefficient for 10 traits, observed that phenotypic correlation coefficient was higher than the genotypic coefficient and it exhibited modifying effect of environments on the binding of the traits. Green fodder yield showed significant and strong positive correlation with leaf area at both genotypic and phenotypic levels. Therefore, this character is useful to the breeders in selecting suitable plant type. Path analysis showed that plant height displayed maximum order of direct effect on green fodder yield followed by stem girth, leaf breadth and leaf stem at genotypic level.
