Path analysis in guinea grass (Panicum maximum jacq.)

Abstract

Twenty four diverse genotypes of guinea grass were assessed to test the path coefficient relation to fix the characters having maximum influence on fodder yield. Path analysis revealed that the maximum direct contribution to fodder yield was through plant height followed by girth of internode. Number of days to 50 per cent flowering, girth of internode and length of panicle also showed indirect contributions towards higher yield. It was also clear from the present investigation that a positive selection can be achieved based on plant height and culm thickness »B tfas fodder crop.
