Complex assessment of varietal resources of the lettuce by means of identification of morphological descriptions and determination of indices of suitability for dissemination in Ukraine is considered. Contemporary classification by botanic and economic and consumption criteria of all the lettuce subspecies has been adapted.

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.

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.

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.
