The article presents the results of studying a degree of self-pollination usual for seven sour-cherry varieties: Solidarnist, Vzglyad, Melitopolska purpurna, Amulet, Rassvet, Vudumka, Melitopolska radist bred in M.F.Sydorenko Institute of Irrigated Fruit Growing UAAS within 2004-2007 yrs. Also the number of pollinizers for these varieties has been picked up from the varieties added to the State Register of Plant Varieties.

The article provides summary of post-registration research on Barley varieties in 2008-2009. Best varieties of Winter and Spring Barley for different climatic and soil conditions of Ukraine are specified, as well as their productivity subject to the influence of environmental factors.

Results of studying of influence of sowing terms on productivity and indices of quality of grain of winter bread wheat variety-innovations of V.M. Remeslo Myronivka Institute of Wheat of NAAS of Ukraine in the conditions of Right-bank Forest-steppe are shown. Negative correlation of productivity of varieties on average temperature of air during the sowing period is shown.

There discussed directions of use for the valuable groats crop, namely Rice, growth rates of its production in Ukraine, options and necessity of creation new verities by breeders, that favors not just the improved nutrition of people, but improves their health, too. And also a full description is provided for new varieties of soybean listed in the Sate Register of Plant Varieties Suitable for Dissemination in Ukraine.

National breeding achievements are described, in particular, of Winter Wheat. Scientific foundation of agricultural crops varietal sources is provided based on functional evaluation of the varieties, criteria for their breeding for specific agro-ecological growing conditions.

Three synthetics of Winter Rye were being observed for the quantity of seminal roots (QSR) to study their inheritance. High inheritance coefficients in a restricted sense were established. Genetic improvement of the Rye may be a result of direct breeding and of using heterosis effect. QSR expressed essentially negative genetic correlation with plant height, positive with grain size, productive bushiness and weight of grain in the ear of successors, as well as with grain yield per unit of the area. Genetic correlation coefficients shall be used in the applied breeding.

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.

The possibilities of utilizing testers different genetical structure are considered. The peculiarities of testers productivity formation are ascertained. The dynamics of influence inbreed lines, testers and one's interaction on hybrids productivity are investigated. The peculiarities of hybrids productivity formation depending on utilizing testers and one's combining are indicated.

Sea buckthorn hardiness to principal winter injures is considered in controlled conditions.
