 ABSTRACT

Correlation and path analysis for fodder yield and its attributing traits were studied in nineteen genotypes of sweet sorghum [Sorghum bicolor (L.) Moench]. Character association analysis revealed significant positive association of green fodder yield with early vigour, plant height, number of leaves per plant, leaf length, number of nodes per plant and internodal length. Path analysis revealed the positive and direct effect of early vigour, plant height, number of leaves per plant, internodal length, leaf to stem ratio and stem girth. These characters may be considered as important yield components. Hence, selection for these characters could bring improvement in yield and yield components.

Key words: Sweet sorghum, Correlation, Path analysis, Green Fodder yield
