The productivity elements of the main ear of soft winter wheat in the conditions of the forest-steppe of the Middle Volga region

Abstract

Research has been conducted on forming the productivity elements of main ear of soft winter wheat in the conditions of the forest-steppe of the middle Volga region. It was found that the productivity of main ear is in a strong positive correlative dependence on a number of seeds per ear and on the mass of 1000 grains. The other elements of the structure were also examined in detail – the ear length, the number of spikelets per ear, intravarietal and intervarietal variability of them.
