Expediency explanation is provided for foundation in the Ukrainian Institute for Plant Variety Examination of Winter Wheat Varieties Resistance to Abiotic Environment Factors Diagnostics Laboratory, as well as for examination of varieties on their suitability for dissemination to provide new approaches and techniques of plant varieties resistance diagnostics; for systematic, indepth and comprehensive studying of the most important adaptive features of plant varieties, which to take into account when registering varieties, national varietal resources formation and seed production organization.

On the basis of literary sources history of origin and development of agriculture is rotined in Ancient. The first Civilizations arose up on fat streamside lands of the large rivers: Nile, Euphrates, tiger, Inda, Ganga and other Earths and plenty of water are fertile during an overflow, a warm climate allowed to Ancient civilizations to grow 2-3 harvests in a year. For the receipt of high harvests, a man had to study the modes of overflow of the rivers, look after heavenly bodies, determine the areas of scopes and terms of leadthrough of the field works. The decision of these questions resulted in the origin of agronomics, astronomy, mathematics. Large harvests were instrumental in the origin of peculiar, enriching of the states, to development of trade and culture on the whole. Riches of country and overpopulation resulted in the origin of wars which one states perished as a result of, second – blossomed. Scientists consider that a high culture, intensive exploitation of soils and aggressiveness of man, brought the most Ancient Civilizations over to the ecological crisis and their elimination.

The perspective hybrid forms between genus Prunus persica (L.) Batch and Prunus amygdalus Batsch, having high ornamental qualities and high resistance to Sphaerotheca pannosa (L v.) var. persicae Woronich., Taphrina deformans (Berk.) Tul., Clasterosporium carpophilum (L. v) Aderh., Monilia cinerea Bonord. have been obtained for using in breeding of peach and nectarine varieties and their rootstocks.

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.

По высоте растений сохранялась симметричность кривой распределения и скопления частот в центральных классах (положительный эксцесс). Впервые предложены символика нового аллеля гена короткостебельности HI-2HI-2 и название донора - Гном 2 (Gnome 2). У донора Гном 2 установлены прямые генетические корреляции высоты растений с числом цветков в колосе, длиной колоса, массой зерна с растения, массой 100 зерен с растения; обратные - с плотностью колоса и массой зерна с колоса. Продуктивная кустистость на 54% обусловлена общими генетическими факторами, из них, в частности, на 30% - аддитивными, а на 24% - неаддитивными. Концепцией генетического усовершенствования продуктивной кустистости ржи Гном 2 предусматривается использование аддитивного эффекта прямым отбором, а также применением селекционных приемов, направленных на овладение эффектом гетерозиса, который обусловлен генами доминантного и эпистатического действия. | Стабілізаційним (доцентровим) добором був створений донор короткостеблості жита озимого (Secale cereale L.) з висотою рослин 50-60 см. Уперше було запропоновано символіку нового алеля гена короткостеблості НІ-2НІ-2 і назву донора Гном 2 (Gnome 2). У донора Гном 2 встановлено прямі генетичні кореляції висоти рослин з кількістю квіток у колосі, довжиною колоса, масою зерна з рослини, масою 100 зерен з рослини; обернені - зі щільністю колоса та масою зерна з колоса.
