    Abstract: The research was conducted to evaluate winter wheat varieties in terms of yield, stability and plasticity in different agro-ecological zones. Ten varieties of winter wheat were sown during 2015-16–2017-18 in two agro-ecological research zones: Forest-Steppe (the V. M. Remeslo Myronivka Institute of Wheat) and Polissia (Nosivka Plant Breeding and Ex... Show More

    Abstract: We studied five parental forms of tomato (Solanum Lycopersicum L.). Were obtained twenty F1 hybrids by the complete diallel scheme (5×5) and used to study inheritance of the average weight of the fruit. Were used as parental forms in the system of diallel crosses according to Hayman V. I. and Jinks I. J.: the line №477 (sp, u), variety Alya (sp) an... Show More
