Abstract
Recurrent selection (R.S.) and Half-Sib (H.S.) selection were conducted to increase oil % in Maize variety (TALAR). Each method consisted of two cycle, each cycle consisted of two growing season. In first season of recurrent selection, full reciprocal diallel cross among ten high oil ears selected from original variety, while in half-sib selection, equal number from each selected high oil ears, bulked and planted, pollen grain were collected from several plants and pollinated other plants. In second season in both method self pollination were performed, and sample of kernels used to oil % determination. The ten high oil content ears will selected to second cycle. Results showed an increasing in oil % from (7.22 to 8.3%) after two cycle of R.S. while in H.S. there were increasing only in first cycle from (7.22 to 7.41) and decreased after second cycle. This result confirmed that recurrent selection performance was superior to half-sib selection. Both selection methods had significant effect on plant and ear height and decrease in ear length and 1000 kernel weight. As well as decreased in heritability in both methods were recorded.
