An investigation was conducted in the Demonstration Farm, Faculty of Agriculture, University of Khartoum, Shambat. for one season (2002/2003) to assess the variation in kernel and pod yield and their components in 19 groundnut genotypes . The layout of the experiment was a complete randomized block design with three replicates. Genotypic and phenotypic variances, genetic coefficient of variation (G.C.V.), heritability, genetic advance and genotypic and phenotypic correlation coefficients between 12 traits were estimated. Significant differences for all traits were obtained, except number of seeds/pod. High genotypic coefficient of variation accompanied with high genetic advance was exhibited by number of branches/plant. Days to 50% flowering days to maturity, number of branches/ plant and number of pods/ plant had high estimates of heritability. Kernel yield/plant was significantly and positively associated, at the genotypic and phenotypic levels, with days to 50% flowering, pod yield/plant and number of pods/ plant.
