Abstract

Goal. To evaluate breeding accessions of common tomato for major economically valuable traits, to select the most valuable ones for further breeding.Results and discussion. The article presents the results of studying common tomato accessions in the main variety trial nursery at the Institute of Irrigated Agriculture in 2011 – 2015, which were used in breeding to create new high-yielding common tomato varieties. Lines L 348 № 2274(82.5 t/ha), L 394 (77.1 t/ha), L 396 (75.3 t/ha), L 352 (75.3 t/ha), L 86 (76.5 t/ha) were the best in terms of the total yield, which exceeded those of varieties Naddniprianskyi 1 and Lahidnyi (standards) by 10 – 21 % and 19 – 30 %, respectively. The evenness of ripening in these accessions was 81 – 87 %; the fruit marketability - 83 – 93 %. New intensive variety Yuvileinyi and promising lines Preliudiia and Kometa were characterized.Conclusions. Promising common tomato lines created at the Institute of Irrigated Agriculture have a high potential performance and are adapted to the southern steppe of Ukraine, which allows using them in breeding to create new varieties of this crop, which would not be inferior to the world analogues.
