This project aims to improve production stability and develop superior tomato varieties to meet different sales demands. Building upon the achievements of the previous project, it plans to select heat-resistant, horticulturally superior medium-to-large-fruited tomato hybrids from natural tomato disease nurseries. This year, it is expected to conduct trial crosses between five tomato lines with excellent horticultural traits and large-fruited tomato lines with good quality performance. The heat resistance of materials obtained from the previous year's trial crosses will be evaluated to select superior new tomato varieties.

▲Figure 1. 10 natural disease nurseries have been collected tomato materials that exhibit resistance to both bacterial wilt and Tomato yellow leaf curl virus.

▲Figure 2. 12 trial crosses have been completed with male-sterilizing and pollination.
