Abstract

Variability, correlation and path coefficient analyses were made for 11 characters in a collection of 99 rice genotypes (Oryza sativa L.). Bacterial blight severity, plant height, spikelets/panicle and grains/panicle showed high heritability with high genetic advance. Yield/plant was positively associated with days to 50 per cent flowering, spikelets/panicle and milling per cent. Path coefficient analysis revealed grains/panicle, spikelets/panicle and bacterial blight severity are the most important characters contributing to yield
