STUDY OF THE COLLECTION OF HYBRIDS OF TOMATO F1 WITH RESISTANCE TO POWDERY MILDEW FOR GROWING IN WINTER GLASS GREENHOUSES

abstract 1501906016 issue 150 pp. 0 – 0 28.06.2019 ru 37
Modern domestic tomato hybrid should be competitive with tomato hybrids of foreign selection. To create a model of a future hybrid, a collection of modern tomato hybrids of domestic and foreign selection presented on the seed market was investigated. During the study, a modern method of genetic study of the genotype of tomato Real-Time PCR was used. As a result of the study, a model of a modern tomato hybrid with tolerance to powdery mildew of tomato was described. In the future, it is planned to carry out breeding work to create such a hybrid. In the course of studying the F1 collection of tomato hybrids, it was found that the modern model of a tomato hybrid should have the following characteristics: a semi-vegetative type of growth with closely spaced internodes, early and medium ripening, a simple type of inflorescence with 4–5 fruits if the average weight of fruit is more than 200 grams; with 6–7 fruits weighing up to 150 grams for collection by tassels. High strength of fruits with the absence of concentric and radial cracking, suitable for long-distance transportation, is required. In the genotype of the modern hybrid model, in addition to tomato powdery mildew resistance (Oidiun lycopersici), it is necessary to have a complex of resistance genes to such diseases as tobacco mosaic virus (Tomato mosaic tobamovirus), Fusarium oxysporum, verticillosis wilt of the tomato; ), brown spot of tomato (Cladosporium fulvum). It is also desirable the presence of a gene of resistance to the yellow leaf curl virus of tomato (Tomato yellow leaf curl virus) and the gall nematode (Meloidogyne incognita)
