An investigation was carried out with 25 restorer lines of sorghum to asses association of grain yield components and their direct and indirect effects on grain yield/panicle during 2008 and 2009 growing seasons in the Arab El-Awamer Research Station, Assiut, Egypt. Results of combined analysis showed that highly significant (p<0.01) variation were recorded among the genotypes for various morphological and yield traits studied. The highest values of 1000-kernel weight (25.8 g), number of kernels/panicle (2114) and grain yield/panicle (54.4g) were obtained from ICSR-94006 genotype, while the lowest values of mentioned traits (28.4g, 688 and 19.5g, respectively) were obtained from GZR4 genotype. Results of correlation analysis indicated that number of kernels/head had positive and highly significant (p<0.01) correlation with grain yield (0.920), whereas, the positive and significant (p<0.05) correlation was found between panicle length and grain yield (0.233). On the other hand there are negative and non-significant correlation (-0.034) between panicle width and grain yield/panicle. The path analysis showed that panicle length had low but positive direct effect on grain yield (0.0111), whereas number of kernels/head had high positive direct effect on grain yield (0.9977) and positive indirect effect was through days to flowering (0.0033), plant height (0.0001), panicle length (0.0002), panicle width (0.0013) and panicle internodes (0.0002), whereas its indirect effect was negative through leaf area (0.0002) and 1000- kernel weight (0.0824).
