Crop capacity and productivity elements of winter wheat domestic sorts have been investigated. Valuable sources on the basis of given characteristics for getting selective material of high quality have been singled out. Correlation relations between crop capacity and productivity elements of winter wheat sorts have been established.

The untypical weather conditions during the extrema drought in 1993- 1994 have been described. Regularities of the accumulation and spending of the dry substance in leaves of varieties, signi ficantly different in productivity, weke considered depending on weather conditions.

Creation of Initial raw for breeding of winter wheat by change of the development type under low temperatures influence was described. Seeds of spring wheat were vernalized in aluminum weighting bottle. By using low temperatures at sawing of M2-6 at the begin ind of optimal terms of sawing of winter wheat, new winter-hardy variety of Voloshkova was bred.
