Evaluation of the combinational ability of beet varieties

Evaluation of the combinational ability of beet varieties is an urgent area of research. Identifying the best parental forms and including them in hybridization will allow obtaining highly productive beet hybrids. The purpose of the study is to identify beet varieties with a high combinational ability, to evaluate the hybrids of the first generation according to economically valuable characteristics. The article discusses the results of many years of research of the ECA of beet varieties and the identification of the best varieties for inclusion in the breeding process. As a result of the research, it was found that in feed varieties a positive effect was obtained in crosses with the participation of the Gloriant sample (the Netherlands), in canteens - Banko (Sweden). The samples of semi-sugar beet were distinguished by high ECA in terms of dry matter yield (105-110%): Babolni Sarga, Monoparte, Monogalben, Tetragroeningia. Table beetroot with a high ECA yield of root crops (114-123%) was characterized by multi-seeded samples of the Netherlands: Uniball, Ran Uniball, Detroit Rubidus.
