Correlation of yield with elements of productivity of varieties of spring soft wheat in the conditions of the steppe zone of the Omsk region

Soft spring wheat is the main food crop of the Russian Federation. Breeding plays an important role in increasing the productivity of wheat. Analysis of correlation relationships and regression relationships between features can be widely used in breeding. The object of the study were varieties of spring soft wheat created by Omsk SAU in collaboration with scientific institutions of the southern Urals and Western Siberia, and varieties SibNIISCH groups of ripening: medium early Memory of Aziyev, Omsk 36; the mid - Duet, Third, Omgau 90; medium Silver, Eritrospermum 59, Simakovsky anniversary, Pavlogradka, Stolypin, Eritrospermum 80-09, Element 22. We have established a strong positive relationship between the mass of grain in the ear and grain yield (r = 0.7) over the years of research on the results of the correlation analysis of the structure elements of the spring wheat harvest varieties,. The average positive relationship was found between the weight of 1000 grains and grain yield (r = 0...
