Stabilizing (centripetal) breeding produced donor of short stem characteristic for winter rye (Secale cereale L.) with height of plants ranging from cm 50 to 60. Distribution curve of plant's height remained symmetric with cummulation of frequencies at central classes (leptokurtic). For the first time, designation for new allele of short-stem gene HI-2HI-2 and donor name Gnome 2 was suggested. Gnome 2 was found to have direct genetic correlation of plant height with number of flowers in the ear, length of the ear, weight of 100 seeds from the plant, as well as reverse correlation with ear density and weight of kernels from the ear.

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.

Вивчено за 11 ознаками технологічної якості емпіричний розподіл частот генотипів, проведено його порівняння з кривою генетично статистичного розподілу. Виявлено наявність переважно правосторонньої асиметрії і позитивного ексцесу за більшістю ознак (вміст іонів Na+, α-N, доброякісність соку, втрата цукру в мелясі, вихід меляси, МВ-фактор) і лівосторонньої асиметрії за вмістом іонів K+ та сухої речовини. Відібрано рослини з популяцій цукристого У 1948-Z та урожайного У 752-Е типів для формування генетичних джерел ознак покращеної технологічної якості коренеплодів буряку цукрового.

Dynamics of technological and sowing indexes of grain of wheat winter-annual kinds of Natsionalna, Stolichna, Artemis in the course of long-term storage is studied. It is positioned that the best sowing indexes throughout all shelf-life the kind of Stolichna, and technological had a kind of Natsionalna. The optimum shelf-life of grain of investigated kinds has compounded six months.

In the article are submitted of bioenergy developments in the world and is provided rating of various types of plants for use in the fitoertergetics. Expresd one’s opinion about criteria descriptions of varieties relatively fitoenergetic using.

The article offers results of research on morphological characteristics and biological properties of blackberry, their inheritance, as well as stability and variability under the influence of agro-ecological conditions and stress factors of the environment with a view of recognizing, describing and identifying varieties undergoing official research and technical examination on DUS, which also could be used in the breeding process.

The results of studies on the major agronomic traits of the best com hybrids of different maturity groups on their suitability to grow in south-western part of the forest- steppe. Use in production practice the proper Selection of hybrids of maize provides an opportunity not only to predict the volume of its production, but also significantly save energy at the post-harvest handling of grains of this crop.

Genetic and statistical analyzes of ten quantitative characteristics inheritance of reciprocal populations F2 of three-hybrid crossing by plant height, leaf blade electroidy and absence of glaucosity on the plants of Winter Rye in three breeding institutions – Nosivskiy Variety Testing Station (VTS), Verhnianskiy VTS and Volynskiy Institute APV. Major portion of phenotype variation has been determined by environmental factors. Genotype variability of those characteristics is predetermined by effects of domination and epitasis, so the breeding aimed at acquirement of heterosis effect when ZKZ (ЗКЗ) and SKZ (СКЗ) are applied is expected to be promising.

The testing of resistances of some varieties of spring oilseed rape to Alternaria has done. The article also shows the results of spread and progression of disease in conditions of different disinfectants and fungicides use. According to the research has identified the best varieties and preparations, which limit the spread and progression of the disease.
