Abstract

The climate change, rising temperatures and drought taking place globally nowadays, are affecting the quality of wheat (Triticum aestivum L.) grains grown in the southern regions of the Republic of Uzbekistan. In order to address this problem, researchers have compared grain quality indicators of 23 local lines of common wheat, bred by hybridization method, with standard varieties of ‘Grom’ and ‘Gozgon’. The main goal of the research into the wheat lines in the test nursery was to select high-crop, high-quality lines adapted to irrigated areas, as part of breeding new varieties of wheat and transfer to agro-ecological competitive variety. The selected standard varieties were planted in the largest area in the southern regions this year. In the experiment, the varieties and lines were placed in 3 replicates, and the data obtained were statistically analyzed. Important indicators of the quality of grain varieties and lines, such as content of protein, gluten, Gluten Deformation Meter (IDK) index and grain vitreousness have been subject to evaluation. The lines of genetically high quality grain after being selected were transferred to the next stage
