The experiment was conducted in the field at the Warka extension to the Agricultural Extension Service Department in the Ministry of Agriculture for the winter season 2022-2021 (north of Muthanna ), With a view to understanding how efficiently five newly introduced genotypes of coarse wheat and determining the best ones for the region’s conditions under the influence of different planting dates, The experiment was applied using Complete Block Design (R.C.B.D.) and Split Plot Design, along with three replications. the four dates for sowing (1/11, 10/11, 20/11 and 30/11) occupied the main plates, while the genotypes (G1133, G65 and G1105 and G1229 and the approved variety for comparison, Bohooth-7, Divided Plots. The findings indicated that the first meeting D1 (1/11) outperformed the number of spikes and the weight of one thousand grains with averages of (334.7 spikes/m2 and 49.99g), while the second date D2 (10/11) was superior in terms of spike count and grain weight, with averages of (50.00 grains, spike-1. and 13.92 tons.ha-1), while the third date D3 (20/11) exceeded the harvest index by (34.57%), While genotype G65 achieved the highest biological yield of 13.00 tons.ha-1, and genotype G1229 achieved the highest average number of spikes, which amounted to 3493 spikes.m-2, and genotype G1133 gave having the most grains per spike, which amounted to 50.97 grains. Spike-1, while the genotype gave Genetic G1105 The highest weight of a thousand grains was 43.93 g.

A field experiment was carried out at the Warka extension farm affiliated to the Agricultural Extension Department in the Ministry of Agriculture (north of Muthanna) during the winter season 2022-2021 (15 km from the center) in order to know the effect of different planting dates on the qualitative characteristics and grain yield of several combinations of coarse wheat. The experiment was applied using the Split Plot Design method and using the complete sectors design (R.C.B.D) and with three replications. The four sowing dates (1/11, 10/11, 20/11 and 30/11) occupied the main plates, while the genotypes (G1133, G65 and G1105 and G1229 and the approved variety for comparison. bohoth-7) Secondary panels. Split Plots. The results showed that the first date D1 (1/11) outperformed the grain protein, specific weight and dry gluten, which averaged 14.100%, 79.83 kg/ha and 9.55%, respectively. While the second date D2 (10/11) outperformed the grain yield 4.54 tons/ha. In succession and the fourth date, D4 (30/11) was superior in wet gluten content, which amounted to 28.59%, while the local cultivar Buhouth-7 was superior in grain protein with an average of 13.633%, while the genotype G1229 was superior in specific weight and content of wet gluten and dry gluten, which averaged 80.83 kg/hectoliter, 28.80% and 9.600%.
