This study was conducted in farmer fields in the Sufia area experiment was conducted in the fields of a farmer in the Sufia area on the right bank of the Euphrates River in the city of Ramadi- Anbar /Iraq during the spring and fall seasons of 2021. By using three genetics populations which selected as promising genotypes from the first selection cycle of Popcorn (A-S2-2, B-S1-3 and B-S2-3) were used in this research and selected as promising genotypes from the first cycle of the Mutual Repeated Selection Program to improve the two cultivars (The local open-pollinated cultivar: Safa and the Argentine synthetic cultivar AGR-5).The selection program for the Flowering silkie trait of the genotypes was implemented in the fall season 2020 with be 14 genotypes. The experiment was carried out according Randomized Compel Block Design RCBD arranged by a split-plot design with three replications. The planting dates occupied the main plots while the genotypes occupied the sub- main plots, to estimate the evaluating the performance of selected genotypes under planting dates and comparing them with two local varieties for the two seasons, and measuring the popping size the experiment results were as follows:The genotypes differed significantly in all the studied traits for the spring and fall seasons, which indicate that the existence of an effective selection effect in these traits, including the total yield, the G2 genotype outperformed by giving the highest mean of yield, number of cobs and weight of 300 grains in both seasons, where the total yield reached 145.79g and 157.43g for the two seasons respectively. The first date in the spring season of 2021 and the third date in the autumn season of 2021 are the two best dates for planting maize through its superiority in most of the studied traits. The 6G genotype selected from the B-S1-3 At the time of first flowering genetic community achieved the highest popping size of 941 and 956 ml for the two seasons, respectively.
