Abstract

A study undertaken with 40 sorghum types revealed the high positive and significant association of plant height, peduncle thickness, leaf number, grain number, grain weight and straw yield with grain yield both at phenotypic and genotypic level. Among the inter-correlations, the positive association of straw yield with days to half bloom, leaf number and plant height was significantly positive. Significant negative associations were observed for panicle length.with grain weight and peduncle thickness. The path coefficient analysis indicated the high direct effects of grain number and grain weight on yield. Plant height, leaf number, peduncle thickness and straw yield had positive indirect effects on grain yield through grain number, but the indirect effects of grain weight and whorl number were negative on grain yield, through number of grains.
