Important aspects of the use of gene carriers of various marker traits in the creation and selection of heterotic tomato hybrids for greenhouse industry are considered. Along with the general requirements for the parent components concerning plant productivity, precocity, resistance to diseases, etc., today, when breeding for heterosis for greenhouse industry, higher requirements are imposed on the source material for the presence of economically useful features. These requirements relate to the type of plant growth, shape, colour and quality of fruits, brush type, stem shape, etc. The characteristics of the initial material for creating heterotic tomato hybrids are presented, as well as the characteristics of the resulting hybrids are given. Studies conducted in the breeding department of the ARRIVG (ARRIVG – a branch of the FSBI FSCV) showed great prospects for the use of gene carriers of various marker traits, especially those that determine the brown colour of the seed endosperm (bs and bs-2 genes) and an undifferentiated peduncle (j-2 gene) in the heterosis breeding of tomatoes for greenhouses. Hybrids and breeding lines created using these marker traits are unique in their own way and are a priority achievement of this scientific institution, since they are of great interest for the heterosis breeding of tomato as a basic material. A number of F1 hybrids are included in the State Register of Breeding Achievements allowed for use (Udacha, Golubchik, Klad ovoschevoda, Zaur, etc.). Due to the development of farming and amateur vegetable growing in recent years, some attention has been paid to the creation of new mutant lines with pink, crimson and dark brown fruits with high taste qualities (given that samples of this type are in high demand among the population and are more expensive). When creating new heterotic hybrids, these features of the parent forms were taken into account.
