There was shown the possibility of assessment of hybrid apple-tree posterity on relation to the drought with the help of mathematical modeling. There was worked out the mathematical model of prognosis character on assessment of apple-tree genotypes to the given stressor. There were offered ways of optimization of hybrid posterity selection conducting in modern selection programs
In conditions of field and laboratory experiments, there were learned particular properties of vegetative reproduction of raspberry varieties. During the experiment, there were used Scromnitza, Glen Ample, Miraj varieties. In field conditions, there were made phenological accounts, also there were made biochemical observations of quality markers of fruits of observed raspberry varieties, based on department of laboratory of pomology of Kuban SAU. Optimal correlation of common sugars and acids, which define fruit tastes, seen on raspberry variety Glen Ample. Maximal amount of planting stocks obtained at reproduction of root stems with a more than 5 mm diameter. Glen Ample had the biggest (in comparison with other varieties) result of output amount of daughter plants. According to commercial – attractable level, raspberry varieties arranged in increasing order: Scromnitza, Miraj, Glen Ample. During the assessment of winter hardiness (based on degree of harming generative buds by frosts), Miraj was positively underlined
The differences of phenotypes of perspective varieties of the apple-trees of Pinova and Honey Crisp and peculiarities of passing the main phenological phases of growth and development, relation to draught, amount and quality of crop yield with the regard to tree stock and conditions of growing were revealed in this research
In cherry breeding aimed to improve fruit quality,
methods of intervarietal, interspecific and remote
hybridization are often used. As a result of the
conducted studies, new promising cherry varieties of
different maturation period, developed in the
conditions of the Lower Volga region by the method
of remote ecologic-genetic hybridization using the
best local varieties, were studied. The most effective
crosses are those developed with use of high-quality
cherry forms Zhukovskaya and Podbelskaya.
According to the aggregate parameters of fruit
quality (dry matter content, sugar-acid index), the
following varieties were positively identified:
Temnookrashennaya, Dubovochka, Lydia,
Rozovaya, Lyubimitsa, Coloritnaya, Korneevskaya,
Loznovskaya, Afina, Sharada, Lexema. The content
of vitamin C - Temnookrashennaya, Lydia,
Coloritnaya, Rozovaya, Lexema. Varieties
Temnookrashennaya, Lydia, Coloritnaya, Rozovaya,
Lexema are offered for use in the canning industry
As the result of 4-year researches there were studied the main economic characteristics of the apple-tree varieties Retina, Renora, Revena Reanda, Remo and Piccolo. The varieties that were positive selected in fruit crop productivity, quality and keeping capacity were recommended for wide productive experiments. There was shown the possibility of use of studied alien varieties as pollinators
The apple-tree varieties of Renet Simirenko, Vagner-Prizovoe and Jonatan were studied in the connection with the ability of their use in technological effectiveness selection
There was shown the perspective of variety-crab use as pollinators of apple-tree plantations. There were shown the economic characteristics of varieties-crabs (terms and length of pollen fertility etc.) There was made the selection of pollinators (crabs) and main industrial varieties for creation of monovarietal apple-tree plantations
