The present state of genofond of the collection that includes 78 taxa supfamily Maloideae C. Web. (Rosaceae Juss.) in DNU Botanical Garden.

У статті представлено результати досліджень і оцінку новозареєстрованих і перспективних сортів ярої пшениці м'якої за генетичним потенціалом, продуктивністю й адаптивністю. Проведено  класифікацію сортів за реакцією на рівні агрофонів і типи вимог до умов вирощування. Підкреслюється необхідність посилення селекції ярої пшениці на стійкість до посухи, хвороб та створення сортів степового екотипу.

The best cabbage lettuce varieties for seedling and non seedling planting under the conditions of the open soil were defined. The potential productivity of the varieties under research in the conditions of the open soil were grounded from the scientific point of view. The influence of planting methods on plants productivity, produvtivity and quality of fresh lettuce heads was analyzed.

The studying results of drought resistance for introdused nectarine varieties in the conditions of South Coast of the Crimea have been given. Four varieties shoved high resistance to drought conditions during two years have been selected.

Indicators of the morphological signs of type of sort on white cabbage plants Dutch flat, Belarus, Amager, Langendijker winter and their variability are the presented. It is established low and average factor of a variation at the majority of the morphological signs. Strong high-quality and ecological variability of signs “height external rake” and “its size leafy parts” at type of sort Dutch flat is defined.

The infection by phytoviruses and the productivity formation in the new varieties of winter bread wheat in the different years with virus damage were investigated. There were identified the varieties being more tolerant to the observed diseases, among these - the samples with different constituents of tolerance, which could be used in the breeding programs.

The article deals with agronomic characters of sugar beet MS hybrids developed on the basis of parental components with resistance to Fusarium rots during vegetation period, which were found in studies with the ecological variety test of Be- taintercross. Possibility of combining high productivity and disease resistance in one genotype was confirmed as matter of principle.

Results of systematization and morphological characteristics of two wheat species-bread (Triticum aestivum L.) and hard (Triticum durum Desf.) are given. Detail descriptions of 55 main varieties of bread wheat and 32 varieties of hard wheat arep- resented in table version. In practical application these result enable plant breeders, seed producers and variety testers to determine wheat varieties easily sinse it is method for morphological systematics of wheat.

Quality of Spring Soft Wheat varieties listed in the State Register of Varieties of Ukraine for 2008, according to the grain quality indices (protein content, flour vigor, bread volume). Over 86% of Winter Wheat varieties bred by Ukrainian breeders are classified according to their quality to the strong and valuable, in contrast to 14 % of foreign varieties. This is the evidence of the Ukrainian breeding varieties ability to compete.

Methodical approaches to the cutting lettuce new varieties morphological characteristics grouping are found with regard to the botanical classification of the species. New morphological characteristics, used for new varieties of plants grouping and examination for distinctness are defined.
