Formation of the elements the productivity of new varieties of spring bread wheat in Forest steppe of Ukraine

The analysis of formation of elements of efficiency at new grades of wheat soft summer is carried out. Certain indicators of efficiency behind reproductive signs. High rates of amount of grains, quantities of cones and weight of grain are found in Leguan, weight of 1000 grains at a Aghur. The smallest variability behind amount of grains Arank grade, quantity of cones – Aghur, the mass of grains and weighing 1000 grains – Aranka and Krasa Polissya possesses. It is established that weather conditions have considerable influence on formation of elements of structure of a crop of spring bread wheat.

The obtained data will help to make reasonably scientifically the program of crossings, to predict identification hozyaystvenno valuable signs that will allow to reduce terms of creation of new highly productive grades.

Key words: productivity, spring bread wheat, varieties.
