There has been given the evaluation of significance of the specific allelic variants of glutenins in the formation of the complex of high indices for grain and flour quality.

Results of the spring wheat of different ecotype variety samples research by economical and biological feature have been reflected, and more valuable samples, which we have used during the breeding with the aim of new varieties creation, have been selected

Authors of the article attempts to describe a state of the problem and accumulated achievements in the flax industry, which are in conjunction with one of the main agronomic remedies, namely fertilization and its influence on the quality of obtained products.

The paper covers results of studying entries of winter wheat competitive strain test for adaptive traits and characteristics of new high producing, winter-hardy cultivar Kolos Myronivshchyny.

Varietal supply with fodder crops of Ukraine’s market and DUS-test of new varieties of plants in 2006 on their suitability for dissemination were analyzed in the article.

In the collection initial material of china squash we found the variety from China Zoria Schodu (Star of Orient) with short length of stem. It is the new genetical donor for the breeding «bush» varieties. Inheritance length of stem in china squash is dominant.

It has been found that post registration variety studying facilitates deeper and overall research of the morphological, agricultural, and biological characteristics and properties of the varieties, as well as it allows to generate national variety resources, based on the selection of complementary varieties for narrow zones and regions. Influence of the agricultural technologies on productivity of different winter wheat types has been studied. Expediency of the post-testing variety studying on two levels of agricultural backgrounds, optimization of the research program, of the research plot areas, diversification of the protective measures against diseases, have been explained.

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.
