While high temperatures adversely affect grain yield, weight, and grain number in plants, drought reduces the amount of organic matter accumulation in plants, slows leaf growth, reduces the working leaf surface through which basic photosynthesis takes place, and results in lower yields, no pointing, and technological quality of grain. The selection of primary material when creating and introducing into the production of new highly productive bread wheat varieties in the irrigated lands of the Republic is the main factor. The need for high-yielding wheat varieties is growing day by day when growing high-quality crops on existing sown areas. The study investigated the relationship between the weight of 1000 grains, natural weight and yield of 47 lines created and selected in local conditions. Based on the results of the research results on productivity indicators, 9 lines were selected and transferred to the next stages.
