This investigation was conducted during the 2018/2019 and 2019/2020 seasons at Sakha Agricultural Research Station, Egypt to study the influence of four planting dates on earliness and yield of fourteen wheat genotypes. The combined analyses showed highly significant differences due to years, sowing dates, genotypes and their interactions for most studied traits. December 5^th was the best sowing date for wheat production. The wheat new genotypes lines 1 and 2 had the lowest days to booting, heading, anthesis and maturity on the other side they had the highest values for grain filling period (GFP) and 1000-kernel weight. Based on the genotype means, the late heading genotype (Giza 163) had short GFP (29.5 days) and possessed a high grain filling rate (233 kg ha^-1 days-¹). The cultivar Misr 3 was superior overall genotypes for grain yield (10.529 t ha.^-1), spikes per square meter (552 spikes), and straw yield (20.164 t ha.^-1); and it ranked first under early sowing date (Nov. 5^th) with 9% higher grain yield overstudied genotypes. According to stability analyses, Misr 3, Sakha 95 and Giza 171 recorded the highest yield, with the regression coefficient values ˃1. This study recommended release of new wheat genotypes (Lines 1 and 2) as new cultivars and use them to develop early maturing and heat-tolerant bread wheat genotypes in breeding programs.
