Journal Title: Science Review - Year 2017, Vol 2, Issue 7
Abstract
It is established that the soft wheat seeds germinating ability, crops survival rate, productive tillering coefficient, productive stems number, the ear length, the number of spikeles in an ear, ear density, an ear grains weight and number and grain yield varied significantly depending on the weather conditions of the years research and the variety features. The studies reveal a significant influence of the varieties on the dynamics of the formation of the leaf surface area, though it is impossible to conclude about superiority of any variety, since the productivity of spring wheat depends on the efficiency of its functioning as well. Accounting the level of formation of the vegetative mass of different varieties, depending on the year of cultivation, showed that the difference between them was not significant, and therefore the advantage of early varieties on the tendency level was revealed in the tillering phase, while in the late varieties – in tube exit phase.
