The article represents summary of post-registration examination of fruit crops, namely Apple and Pear in 2008s-2009s. Best varieties of Apple and Pear in different soil and climatic areas are highlighted.

The article highlights Kharkiv Breeding Facility, later referred to as Plant Production Institute named after V. Iuryev in 20s-80s concerning breeding the Winter Wheat in Ukraine and impact of the varieties obtained on th productivity increase. It is established that thanks to the efforts of V. Iuryev, V. Didus, M. Ielnikov, A. Shulyndina and others for the period of 1920s-1980s a number of economically valuable varieties have been created – Multrum 120, Iuryivka, Lutetsnes 266, Zenitka, Salut, Kharkivska 1, Kharkivska 32, Khar-kivska 81 and others. Thanks to efforts in breeding the yield index was growing gradually and reached the average level of 4,3 tons per hectare. In particular, in 1921–1930 – 2,33 ton/hectare, 1931–1940 – 2,42, 1941– 1950 – 3,01, 1951–1960 – 26,5, 1961 – 1970 – 4,3, 1971–1980 – 5,05, 1981–1990 – 4,47 t/hectare. In recompense for significant achievements in agricultural crops varieties breeding a breeding center was founded at the facilities of Plant Production Institute named after V Iuryev was founded in 1976.

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.

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 represents summary of post-registration examination of fruit crops, namely Apple and Pear in 2008s-2009s. Best varieties of Apple and Pear in different soil and climatic areas are highlighted.

The features of sugar beet polygerm seed populations were studied. The ways of creation of combinationaluable pollenizers line –– component hybrid on sterile base were improve. The environment conditions had influenced on reaction of different types of genic interactions in specific sets of hybrids. The positive effects of interaction is a part of heterosis effects. It is proved that plasticity and stability effect depend on environment condition where genotype realization occurs.

Impact of rates of sawing of seed and fertilization on seed productivity of Kameniar and Irma Long Fiber Flax in the conditions of Ukrainian Woodlands are highlighted. A trustworthy proportion is established of factors influence, in particular, of the sawing and fertilization rates, on Long Fiber Flax yield formation.

It is concluded by investigations that wheat crossing of various development types between themselves cause increase of formbuilding process in hybrid progeny, promoting the selection of practically valuable recombinats. The genotypes which present the practical valuable by complex of adaptive traits and properties have been selected by phenotype stability in the breeding process. The new bread winter wheat variety Pamyati Remesla developed with participation of spring wheat variety Hja 22139 (Finland) has been proposed for including it into the Register of Plant varieties of Ukraine adapted for use in Steppe, Forest- Steppe and Woodland of Ukraine since 2010.

In first time it is used the marker genes’ donor of dominant stem shortness, recession erective leaf and absence of waxen plants’ cover for the receipt of F1 hybrid plants of winter rye. It is certain the parameters and character of intercommunications for ten quantitative signs at F1 hybrids from crossing of rye standards with distinctive morphological signs.
