It is shown that under the influence of the hp-1 gene in tomato fruits, the content of vitamin C increased by an average of 55% to the level of 39.54 mg / 100 g. The presence of the hp-2dg gene increased the vitamin C content by 50%. The genotypes hp-1w and hp-2j in terms of vitamin C content exceeded the standard variety by 27.43 mg / 100g and 33.92 mg / 100g. The gs and gf genes did not have a significant effect on the content of soluble dry matter, total sugar, titratable acids and vitamin C in the fruit. In the nursery of competitive variety testing on the complex of economically valuable traits selected variety Vechirnya Gouache, which had an average yield of 44.3 t / ha, plum-red fruits, average weight 43.4 g, soluble dry matter content 4.77%, total sugar - 3.56%, vitamin C - 20.99 mg / 100g, titratable acidity at the level of 0.39%. The sample is marked by a set of signs of suitability for industrial cultivation and is suitable for processing and canning. In the protected soil was isolated hybrid Peremozhets´ F1 with a yield of 19.6 kg / m2, average fruit weight 198.1 g, duration of the period from germination to 125 days, soluble dry matter content 4.27%, total sugar – 2.99% , vitamin C – 26.24 mg / 100g, titratable acidity – 0.28%.   Product Description popup.authors Krutko Roman V popup.nrat_date 2021-03-17 Close
