THE CURRENT research aimed to evaluate and select bread wheat stable cultivars withhigh productivity across diverse sowing dates. Fourteen wheat cultivars were grown in a randomized complete block design with three replicates at six sowing dates during two successive seasons of 2018/2019 and 2019/2020 representing twelve environments. The cultivars were evaluated for grain yield and its attributes. Highly significant differences were obtained among the wheat cultivars, sowing dates, and their respective interaction for all measured traits. The highest grain yield (2.992-ton fed-1) was recorded on 30th November, after this date, each day delay in sowing of wheat onward decreases grain yield at the rate of 21kg fed-1 day-1. Overall, the cultivar Gemiza 11 gave the highest grain yield with an average of 2.861 ton fed-1, recorded the highest 1000-GW with an average of 47.73 g, highest straw yield with an average of 8.303-ton Fed-1, and was the earliest cultivar with a mean heading date of 92.9 days. According to GGE biplot results, Gemiza 11, Gemiza 9, and Sakha 94 ranked in the first order as high-yielding cultivars and had greater stability level overall sowing dates under. Assiut conditions. The most adequate cultivars for sowing in the first half of November (1st -15th ) are Misr 2, Sids 12, Sakha 95, Gemiza 9, and Gemiza 11. Also, Sakha 94, Gemiza 9, and Gemiza 11 can be sown after 30th November because they produce a satisfied yield, have good stability, and can be considered as late sowing tolerant.
