WAYS TO REDUCE THE COST OF PRODUCTION OF PLANTING MATERIAL IN VITRO

New data on the effectiveness of using the in vitro vine collection for growing healthy planting material are presented. The collection is maintained in vitro in the biotechnology laboratory of the All-Russian Research Institute for Viticulture and Winemaking named after Ya.I. Potapenko − branch of FSBSI «Federal Rostov Agricultural Research Center» by reducing the number of subcultivations. One of the directions of the laboratory's research is the search for ways to maintain the collection in conditions of slow growth, which reduces the cost of maintenance and contributes to the preservation of plants. This article presents data that the cultivation of vine planting material (micro-plants in vitro) based on the collection is more cost-effective than the full cycle (from excision meristem to obtaining planting material in vitro).
