Conjugacy of productivity indicators of spring wheat of the Iren variety in the conditions of the south of Western Siberia

The article presents the results of research on the Iren variety of spring soft wheat in the conditions of the forest-steppe of the Ob region of the Altai Territory in order to identify the correlation of productivity signs. The results obtained over two years of research have shown that the signs of grain weight in the ear and the mass of 1000 grains have a direct strong influence on the yield value. A high positive correlation (r > 0.7) is determined between the characteristics: yield and mass of 1000 grains (r = 0.7222), grain mass in the ear and mass of 1000 grains (r =0.8352), yield and grain mass in the ear (r = 0.9497).
