Study of Crop Yield Elements of Hard Wheat in Fourth Generation (F4) Hybrid Lines (Azerbaijan)

Abstract

In the article, the productivity elements of 40 intraspecific fourth generation (F4) hybrid lines of hard wheat were studied in comparison with the standard Fertile-95 hard wheat variety under irrigation conditions at the Absheron Auxiliary Experimental Farm of the Research Institute of Crop Husbandry, in the 2019-2020 vegetation year. As a result of research, it is recommended to select hybrid lines with catalog number k-ST/2016/13, k-ST/2016/65, k-ST/2016/173, k-ST/2016/174, k-ST/2016/176, k-ST/2016/18a etc. and use them in the hybridization process in order to enrich the germplasm of local wheat genotypes as a valuable starting material with high productivity elements and in order to create new varieties of hard wheat, it was included in the experiment at the irrigated (Tarter Regional Experimental Station, Araz Science Production Union of Nakhchivan Autonomous Republic) and non-humidified (Jalilabad Regional Experimental Station) regions of the republic.
