Giving regard to the main elements of Winter Wheat varieties assessment when selecting frost resistant plants and taking into account genetic potential of the parents, date of hybrids sowing and their assessment by the speed of spring vegetation, it is possible in the sense of successful breeding to derive the most steady genotypes by the specified characteristics starting from F1. hybrids.

Outcomes of reciprocal crossings new Rye donor of super-short stem with electroidness Hl-3Hl-3elel and tall Rye Variety Viatka 2 are provided. The firs generation hybrids appeared to have a short stem with regular leaf blade. In the second generation the female parent effect of short stem domination was established, as well as complete domination of tall bushiness, long-spiked plants, increased number or grains in the ear. Weight of 100 grains in the ear made 22,79 і 29, 41% of the heterosis relative to the best parent. According to the results of the research of genetic and statistical parameters of F2 breeding characteristics plants with electoid leaf blade shape were selected.

When studying period of maturation after harvest, varietal specificity of level of winter wheat seed maturation process reaction on hydrothermical factors has been revealed. This trait should been taken into consideration when deciding practical problems in respect to rational variety-regionizing as well as to development of seed technology based on biological peculiarities.
