FIELD: agriculture, in particular, plant selection. SUBSTANCE: method involves providing artificial pollination by means of cut plant stems enclosed in paper isolator; placing cut plant stems in nutrient solution and holding in refrigerator at decreased positive temperature before carrying out artificial pollination. Nutrient solution contains sugar 25-30 g, citric acid 5 g, chloramine 30 mg and thymol 5 crystals per 1 l of water. Method further involves removing cut plant stem from refrigerator, castrating and carrying out artificial pollination in laboratory or under field conditions.
