Kolisnik Oleg Nikolaevich – Сandidate of agricultural sciences Sciences, associate Professor of the Department of Botany, Genetics and Plant Protection of the Vinnitsa National Agrarian University (21008, Vinnytsia, Soniachna Str. 3, e-mail: ooov@i.ua).

The stability of hybrids to the bile duct depends on the number of resistant to this disease of parental forms. The study of the degree of inheritance of resistance to flying sauce by determining the correlation dependence of stability between hybrids and their parental forms showed that the highest correlation relationship was established between hybrids and the average of both parent forms (r = 0.711; 0.671), as well as between hybrids and maternal forms ( g = 0.552; 0.527). The obtained results indicate the close dependence of hybrids on both parent forms, as well as on the superiority of maternal inheritance. To obtain hybrids of corn resistant to flying canoes, it is necessary to select high-yielding and resistant to pests and diseases both parental forms, as indicated by the correlation between the simple hybrids and the average value of the parent forms (r = 0,508 ... 0,926), according to the relevant features.
