It was resistant to tomato yellow leaf curl virus (TYLCV), tomato mosaic virus (ToMV), leaf disease and crown rot. It had strong continuous fruit setting ability, so the yield was high, which was over 8 000 kg per 667 m2. It was suitable for cultivation in protected areas in long seasons especially in protected areas in autumn and winter and in areas with high virus incidence.
