Recurrent selection is the most common mean for indirectly enhancing inbred lines performance by enhancing the performance of their sources of populations. We compared the  effectiveness of two intrapopulation selection methods of S₁ progeny and half-sib progeny viaDesign I mating scheme in improving the yield of Nubaria yellow maize population (NYP)  (C₀). For fairer comparison, we unified germplasm used in the two methods by using S₁ seeds supposed to be kept for recombination in half-sib family selection as a germplasm of S₁ family selection. This permitted studying the outbred and inbred progeny for the same parent providing the prospect for combined selection on which selection unit is the parent family (both half-sib and S₁ families for the same parent). In recombination season, at harvest, S₁ topcrosses of each improved population were separated to examine the general combining ability of each recombined S₁. The three resulting improved populations via their respective S₁ topcrosses were under evaluation with the original and the check populations. Significant differences were detected among S₁ topcrosses for grain yield trait. Actual gain for grain yield (3.9 and 3.7 ard/fad for S₁ and H.S.family selection methods, respectively) were apparently one-half the predicted gain. Grain yield has improved significantly through this cycle with an increase up to 32 % than the original population. Theimproved population by combined selection was the highest yielding followed by the improved by S₁ family selection then the improved by half-sib family selection with non significant differences among the three improved populations. We recommend with using the improved population resulting from the combined selection as a sub-population and combining the three improved populations seeds without those of S₁ topcrosses with low-performance in one population used for isolation and as a material for the coming improving cycles of recurrent selection.
