dc.description.abstract Groundnut (Arachis hypogaea L.) is one of the main cash and food crops in the world. Sudan is one of the major African producing and exporting countries. The crop is produced in the Sudan under irrigation and rain fed conditions. This study was conducted at the Gezira Research Station Farm, Wad Medani, Sudan in season 2015 to assess the genetic variability, heritability in broad sense, genetic advance and traits associations in 53 groundnut genotypes. The genotypes and checks were tested using an augmented design with five blocks. The characters measured included days to 50% flowering, plant height, number of branches/plant, pod yield/plant, number of pods/plant, number of double seeded pods/plant, number of single seeded pods/plant, kernels weight/plant, 100-seed weight, shelling out-turn %, hay weight/plant, total plant weight, harvest index and pod yield/ha. Significant differences were recorded for shoot length, root length, root volume, root shoot ratio, number of pods/plant and number of double seeded pods/plant. High genotypic coefficient of variation (46.6) accompanied with high genetic advance as percentage (88.3) was exhibited by number of pods/plant. Number of pods/plant (84.6%), number of double seeded pods/plant (86.3%), kernels weight/plant (71.1%), shelling out-turn % (62.1%), harvest index (58.9%) and pod yield/ha (55.1%) had high estimates of heritability. Highly significant positive and moderate correlation coefficients were found among the parameters, particularly total pod yield/hectare with number of pods/plant (0.379**) and number of double seeded pods/plant (0.424**). The highest genotype in pod yield/ha was (ICGV-94217) which produced (4257kg/ha). The genotypes ICGV-94216, ICGV-94204 and ICGV-88398 proved to be the best for pods yield per plant (24.3, 23.2, 22.9) and number of double seeded pod per plant (22.6, 22.6, 22.6) respectively, compared to the best check Tozi, therefore it could be subjected to further investigation on genetic improvement and yield. For the improvement of cultivated groundnut, it is pertinent to use diverse collections with more variability for the purpose of variety development and for using them in the future breeding programs in the Sudan. en_US
