Variability Heritability and Genetic Advance of Some Groundnut Genotypes (Arachis Hypogaea L.) under Saline Sodic Soil

An investigation was carried out at the demonstration farm of Soba research station for reclamation of saline and sodic soils, Khartoum, Sudan, during three successive growing seasons of (2012/13-2013/14-2014/15). The trail was conducted in a randomized block design with three replications to study genetic variability, heritability and genetic advance of yield and yield contributing characters in eight groundnut genotypes under saline sodic soil.Highly significant variations were observed for all characters under studies.High genotypic and phenotypic coefficients of variation were observed for all characters except days to 50% flowering, plant high, pod yield/ha and seed yield/ha.High heritability estimate coupled with high genetic advance were obtained with number of pod/plant, number of seed/plant, pod yield/plant, seed yield/plant and 100 seed mass.
