- Global and local climate changes require the development of new cultivars. An answer to this, an immune breeding program “Analogue” for grapevine was developed at the All-Russian National Research Institute for Viticulture and Winemaking “Magarach”. The program aims at improving the efficiency of grape breeding and producing new cultivars that are resistant to a variety of pests, diseases and environmental stress factors, in combination with fruit quality comparable to other cultivars at the international level. The concept of the models we suggested is based on 16 most desired selection traits that had been chosen from the existing selection pool, identification of the original forms for crossbreeding and multivariate analyses. To facilitate cooperation with other research centers, the information obtained was encoded according to OIV - Bioversity International descriptors. Using the developed models for the creation of new cultivars will, on the one hand, help solve ecological problems in the vineyards, while on the other hand, will ensure high economic effectiveness of viticulture and winemaking, as well as produce grape cultivars for different purposes.
