2018

The success and timing of new varieties largely depend on the correct selection of the source material, representing the initial stage of breeding. This is especially true for plant species that have a two-year development cycle. The purpose of our research was to obtain intraspecific hybrids of chicory root. Research was carried out in the traditional area of growing root chicory – Rostov region of the Yaroslavl region. For testing the breeding process and obtaining promising lines us in 2014, there were direct steam crossing. A total of 14 samples of hybrid seeds were obtained, which were 2015-2016 sown for testing in the nursery source material. The article presents the data on the study of intraspecific hybrids of chicory root, they are evaluated in the nursery of the source material on yield, marketability, root shape, resistance to root rot during the growing season. Production requires varieties with short root, in which the bulk is concentrated in the upper part, combining high yields and resistance to root rot during the growing season. Among the hybrids dominated the cylindrical shape of the root. The conical shape had rooms Г1432 and Г1442 with root length of 20.0 cm, curved short form (16 cm) of root was different sample Г1462. This sample stood out spread sheet outlet with a strong anthocyanin coloration. As the yield of roots separated rooms Г1432, Г1452 and Г1441 (3.6; 3.4 and 3.7 kg/m2, representing a cash consideration of 133.3; and 127.0- 138.6% of the standard).
