The author has reserched the resistance of scab-immune apple cultivarsbelonging to different ecological and geographical groups to unfavorable water regime conditions and temperature stressors in summer. The comparative studies of their drought and heat-resistance have been carried out. According to the complex of the water regime idexes the cvs "Orlovskoye Polyesye", "Florina", "Imant", "Amulet" and "Vitos" have been seleted as the most drought-adapted and higt heat-resistant.

The drought-resistance of 15 nectarine varieties and forms with a sign of male infertility is studied. The research identified genotypes with varying degrees of drought-resistance. The greatest degree of drought-resistance demonstrated the form 33-3-1, 512-86,41-15-2, and grade Kul'dzhinskiy 4x, Krymtsuht, Elbertaziya.

Analyzes of national varietal resources of white cabbage by maturity groups has been conducted. Correlative ties of quantitative characteristics of bearing organs of white cabbage (Brassika oleraceae L. var. capitata (L.) Alba DC.) are explained and grounded scientifically with morphological characteristics indicated.

У F2 проведено гібридологічний аналіз 80 сімей реципрокних гібридів від схрещування зразків жита з ознаками високорослості, звисаючої листкової пластинки, воскового нальоту (hlhlElElWcWc (сорт В’ятка 2) з новим донором альтернативних ознак – домінантної короткостеблості, рецесивних еректоїдності і відсутності воскового нальоту на листках і стеблах (HlHlelelwcwc). Дослід проведено за однаковою схемою у трьох екологічних місцях: Носівській СДС, Верхняцькій СДС і Волинському ІАПВ. Вперше отримані результати, які відповідають тригібридній схемі розщеплення відповідно до 27;9;9;9;3;3;3;1, повсюдно в цілому. Аналіз достовірно підтвердив розщеплення по трьох парах незалежних генів.

Частный приусадебный сектор в Республике Беларусь, не взирая ни на какие экономические трудности, стабильно развивается. Частники, как и основные сельхозпроизводители, хотят видеть у себя на грядках или на полях новые продуктивные сорта в широком ассортименте с гарантированным результатом осенью во время уборки урожая. Причем требование любителя-овощевода также может заключаться не только в высоком урожае, но и в получении экзотического результата, например, перцев ультрафиолетового цвета, вкусных арбузов, выращенных в условиях Беларуси и т. д.

Such varieties of winter wheat as Ovidium, Kokhana, Blago, Maria, Andromeda possess high adaptive potential, there are possible to use on irrigated and unirrigated lands. New genotypes are able to guarantee yield on level accordingly 9,0-9,5 and 5,5-6,0 t/ha. They are form the grain of strong and valuable wh eats.
