Relevance. Tomato hybrids of the "beef" type are a commodity group characterized by fruits whose mass exceeds 220-240 g. The fruits of this group are distinguished by an attractive aligned shape and color, large size and are in constant demand among consumers. In the assortment of supermarkets and markets, the share of "beef" tomatoes is 10-20% of the total volume. Methods. The results of studying the characteristics of tomato hybrids allowed us to identify the most valuable characteristics for selection in the selection of "beef" tomatoes. Traditionally, we select donor lines for the signs "fruit weight from 200 g and above", "high yield", "disease resistance". For hybrids of professional use, we also evaluate such characteristics as" fruit density", "high uniformity", "ability to form fruits with high uniformity and marketability throughout the growing season". For hybrids and varieties for the hobby market, the most important characteristics are "High taste qualities", "aroma", "high dry matter content". Results. As a result of selections based on these characteristics, such hybrids as Rumyani shar F1, Korallovy rif F1 (which are in demand not only in our country, but also in other countries), Katarina F1 were created.
