The paper presents data on the response of F2 hybrid combinations and parental forms of tomato at different temperatures (optimal 250C and stressful 400, 420C), tested in laboratory conditions. It was established that stressful temperatures significantly affect the early ontogenesis of tomato varieties and hybrids by suppressing the growth of the embryonic root, stem and seedling (sometimes by stimulating them). Cluster analysis by the k-media method demonstrated that stressful temperatures manifested a higher discriminating ability of tomato clusters for seedling length and embryonic root length characters, which reveals a more pronounced specificity of interaction at these temperatures. Florina, Wake, Prestij and Rome varieties and F2 hybrid combinations Mary Gratefullt x Pontina, Prestij x Pontina, Rome x Wake have the highest complex resistance in terms of the reaction of the embryonic root, stem and seedling at 420C temperature. They are of interest in the further process of breeding. |
