DETERMINATION OF THE PRODUCTIVITY POTENTIAL OF THE EAR OF BREEDING MATERIAL OF SOFT SPRING WHEAT

This article presents experimental data from two years of research to determine the productivity potential of an ear of soft spring wheat. Soft spring wheat is the most important agricultural crop, therefore, the issue of increasing its yield, which consists of the sum of the effects on productivity characteristics, is always relevant. In this experiment, an analysis of these characteristics was carried out to determine the possibility of using cultivars from the collection of soft spring wheat and the Darya standard variety in breeding work. The productivity of an ear of spring wheat is determined by several factors and is an important component of grain yield. High ear productivity, as a rule, positively correlates with the overall yield. The main factors affecting the productivity of an ear of spring wheat are: the number of grains in an ear, the more grains in an ear, the higher the potential productivity; the weight of grain from an ear is also closely related to yield and depends on growing conditions; the number of spikelets in an ear can contribute to an increase in the number of grains of breeding material for soft spring wheat based on the productivity of the ear. The productivity potential of the ear of promising lines of soft spring wheat was determined and forms with values exceeding the standard grade were selected, these are the breeding lines L-57, Sumer V.Lis and Sumer VS. Also, a comparative assessment of the ear water content was carried out according to the ledges between the Darya standard variety and the Sumer V.Lis breeding line with the maximum amount of grain in the ear.
