This project aims to improve production stability and develop superior tomato varieties to meet different sales demands. Building upon the results of the previous project, we planed to conduct heat-resistant pollen trials to select heat-resistant and horticulturally superior medium-to-large-fruited tomato hybrids. This year, five tomato lines with good horticultural traits was crossed with heat-resistant tomato lines, and the heat resistance of seedlings obtained from the previous year's trials were evaluated.
