The results of the study of heterosis hybrids of tomato in the open field in non-chernozem zone of Russia

Development of F 1 hybrids of tomato for open ground at the moment is one of the main tasks. It can be solved only if there are parent forms with valuable features and properties. As a result of three years of research of tomato hybrid combinations and parental lines in the open field in the non-chernozem zone, the heterosis on major economic traits has been revealed. The character of inheritance of studied traits and the degree of dominance have been determined. The groups of hybrid combinations with high heterosis effect and parental lines that contribute to this effect were identified.
