Abstract
Description
Thus, the primary task of breeding is to create varieties
that combine high yield with drought resistance. It is important to have a
sufficiently high level of adaptability of the variety to the conditions of the
growing region, where the variety remains the main reserve for resource
conservation and intensification of agricultural production in Ukraine.
Generally accepted methods are used, namely scientific, special, laboratory,
mathematical and statistical. In conditions of insufficient moisture, the use
of early maturing and very early maturing varieties is relevant. Indicators of
soybean yield in all oblasts of Ukraine are provided. According to the results
of the analysis of 17-year meteorological observations, it was found that the
climatic characteristics of Poltava oblast became more arid. The dynamics
of indicators of the soybean gross yield in Poltava oblast (2002–2018) is
analyzed against the background of the amount of precipitation during the
growing season (4–8 months). In the research laboratory of Breeding, Seed
Production and Varietal Soybean Agrotechnics of Poltava State Agrarian
University, it was created Almaz, Antratsyt, Adamos, Aleksandryt,
Akvamaryn, Avantiuryn soybean varieties, which were listed the State
Register of Plant Varieties Suitable for Spreading in Ukraine. Indicators of
agricultural suitability of these varieties and their advantages are presented.
Varieties of Poltava breeding are distinguished by drought resistance. These varieties are guaranteed predecessors for winter crops in the Steppe and Forest-Steppe of Ukraine.
