Tomato varieties were evaluated during winter-spring growing season at experimental station of the Uzbek Research Institute of Vegetable, Melon Crops and Potato (UzRIVMCP). Six hybrids and one conventional cultivar were tested in Korean double-layered, single-span plastic greenhouses. These greenhouses were built under Uzbek-Korean collaborative research project. Variety trials were carried out to evaluate and select most suitable tomato varieties for growing in specific microclimate conditions which are created in double layered plastic greenhouses. Tomato hybrids F1 Beton and F1 Chelbas had significantly higher total and marketable yields compared to standard variety, and these varieties will be recommended for The State Variety Testing for further evaluations.
