The authors present the results of estimating seven raspberry cultivars - 'Novokutaivs'ka'(c), 'Phenomen' (c), 'Sanya', 'Perseya', 'Gusar', 'Kryepysh' and 'Strunka' - concerning their capability of forming yield depending on the cultivation year weather conditions. The cv 'Gusar' has been selected which had the highest yield of high-quality berries for two years of researches (2009-2010).

The article reflects the progress of genetic decrease of Rye F 3k- 10029/ Saratovske (Саратовське) 4 height by means of the shortest stem plants selection during the period from 1974 to 2010. 37 years selection of the shortest- stern genotypes decreased the plants height from 119.33 cm to 22.57cm. Targeted selection into minus direction decreased the plants height in 5,29 times on the background of the dominant HI expression. In average, the height of plants in the course of 27 breeding cycles were decreasing by 2.69 cm, but that was not going gradually. A new donor Gnom 3 had been created for ultra short-stem trait of the Winter Rye, with the marking of alleles HI-3HI-3. Relative influence on the minus selection efficiency has been established by height of plants for the selection differential (38%) and coefficient of inheritance in narrow sense (14,56%). Realized efficiency of selection in decrease of winter rye height in 72,08% of cases corresponded to predicted hit ration of the breeding. Analyzes of genetic and statistical parameters and correlation clusters of 11 utilitarian average characteristics of ultra short- stem rye Gnom 3 for the period of 1974 to 2010 has been performed.

Purpose. Determining prospects of introducing Callistephus chinensis cultivars of foreign breeding for further cultivation under conditions of the Central Forest-Steppe zone of Ukraine. Methods. Field, laboratory, analytical and statistical ones. Results. Ten C. сhinensis cultivars of theGerman breeding were tested under conditions of the Central Forest-Steppe zone of Ukraine. Biomorphological traits of the varieties of five sort types were identified, and their comparative analysis was conducted. Seasonal dynamics of growth and development of cultivars in the growing area was studied. Conclusions. Cultivars with short and mean duration phases of development can be grown under conditions of the Central Forest-Steppe zone of Ukraine by direct sowing that does not affect their seed productivity and sowing quality of seeds. Seeds of late cultivars can reach complete maturity only in case of seedling use. C. chinensis cultivars of the German breeding have successfully passed the initial test for suitability to introduction into the studied area.

The estimation of drought hardiness of sea buckthorn varieties of different environmental and geographical origin was made in the field and laboratory conditions. In late August the drought hardiness was estimated according to leaf injures and abscission in the field conditions. In the laboratory conditions were determined the main characteristics of water regime: tissue water saturation, water deficit, leaf water retaining ability. As a consequence, the studied varieties were divided into groups with different drought hardiness degree.

Phytopathogenic fungi in the order Diaporthales (Sordariomycetes) cause diseases on numerous economically important crops worldwide. In this study, we reassessed the diaporthalean species associated with prominent diseases of strawberry, namely leaf blight, leaf blotch, root rot and petiole blight, based on molecular data and morphological characters using fresh and herbarium collections. Combined analyses of four nuclear loci, 28S ribosomal DNA/large subunit rDNA (LSU), ribosomal internal transcribed spacers 1 and 2 with 5.8S ribosomal DNA (ITS), and partial sequences of second largest subunit of RNA polymerase II (RPB2) and translation elongation factor 1-a (TEF1), were used to reconstruct a phylogeny for these pathogens. Results confirmed that the leaf blight pathogen formerly known as Phomopsis obscurans belongs in the family Melanconiellaceae and is not congeneric with Diaporthe (syn. Phomopsis). A new genus Paraphomopsis is introduced herein with a new combination, Paraphomopsis obscurans, to accommodate the leaf blight fungus. Gnomoniopsis fragariae comb. nov. (Gnomoniaceae), is introduced to accommodate Gnomoniopsis fructicola, the cause of leaf blotch of strawberry. Fresh collections and new molecular data were incorporated for the recently typified species, Paragnomia fragariae (Sydowiellace), which causes petiole blight and root rot of Fragaria spp. and is distinct from the above taxa. An updated multi-locus phylogeny for the Diaporthales is provided to place and distinguish the leaf blight and leaf blotch pathogen, as well as the species associated with petiole blight and root rot of strawberry.

Gnomoniopsis fragariae comb. nov. (Gnomoniaceae), is introduced to accommodate Gnomoniopsis fructicola, the cause of leaf blotch of strawberry. Both of the fungi causing leaf blight and leaf blotch were epitypified.

An updated multilocus phylogeny for the Diaporthales is provided with representatives of currently known families.

The article researched genetic potential, morpho-biological characteristics and features of new varieties of winter wheat varieties of semi-dwarf and short-stem types. It was established that new generation of such varieties displayed improved architectonic of plants, as well as a complex of morphological and economical value chararacteristics and features, combined high genetic potential of productivity with good adopting features, and short stem with high resistance to drowning, and generated higher crop capacity compared to conventional mid-ripening varieties.

Discussed problems of planetary changes of climate, through that it is necessary to revise the terms of sowing of winter crops, and also structure of sowing of agricultural cultures. The brought transpiration coefficients over of basic agricultural cultures, that must be taken into account for forming of structure of their sowing. On the example of wheat winter-annual the done attempt to be determined with priority directions in the selection of agricultural cultures.
