Abstract
This research was conducted to investigate the correlation and path coefficient analysis of thirty three genotypes for green fodder yield and its attributes of forage sorghum. The experimental material was planted in Completely Randomized Block Design (RBD)in three replication during Kharif in the year 2019-20 at Crop Research Centre, SVPUA&T, Modipuram, Meerut - 250110 (U.P.). The study of association and path analysis evaluation carried out using the ten green fodder yield traits, viz., days to 50% flowering, plant height, leaf length, leaf breadth, leaf area, stem girth, leaves per plant, leaf stem ratio, total soluble solids and green fodder yield per plant. There is significant and positive correlation with green fodder yield per plant was exhibited with stem girth, leaves per plant, leaf length, leaf breadth, leaf stem ratio and total soluble solids at genotypic and phenotypic level. While leaf area showed the maximal direct effect on green fodder yield per plant followed by stem girth, leaves per plant and leaf stem ratio. There for selection for these traits is advisable for improving the character of green fodder yield.
