Abstract: 
In order to compare the effect of three selection methods. forty-eight sorghum varieties and inbreds were planted in duplicated trials, one of which was irrigated. The effect of relative drought on grain yield, ears per plot, seeds per ear, thousand-seed mass, biomass, seeds per plot and harvest index were determined. Seven genotypes from each of the varieties and inbreds were selected by three different methods. The resultant changes in the means of each characteristic of the genotypes indicated that in order to increase a cultivars' drought resistance, yield potential may have to be sacrificed. Therefore, yield potential needs to be included in the formation of a selection index for drought resistance. This selection index could include either the maintenance under increasing moisture stress of harvest index or grain yield.
