Адаптивний потенціал гібридів соняшнику до умов східної частини Лісостепу України

Abstract

In accord with the many-year study results the differentiation of sun-flower hybrids for adaptability to the conditions of the eastern part of the For-est-Steppe of Ukraine has been conducted. The types of hybrids with an opti-mal response to ecological conditions have been determined; the best ones with a high level of grain yield have been selected. It is shown that for breeding work the analysis of the peculiar feature of a hybrid for the specificity of reac-tion to bioclimatic factors and their combination is of great importance
