In the regional experiment of tomato cultivar in Guizhou, the plant height was 158.6 cm, the first fruit node was 5.4, the internode length was 6.16 cm, the number of nodes from the first inflorescence to the second inflorescence was 4.8, the stem diameter was 11.5 mm and the leaf unfolding degree was 76.8 cm. ''Jinfen'' was unlimited growth type, the average number of fruit per ear was 5-6, the fruit color was pink with bright, the fruit was round, the single fruit quality was 250-280 g, and the yield of single plant was 3.82 kg. The cultivar had excellent fruit hardness, cracking resistance and high commercial fruit rate. The average yield was 138 242.7 kg/hm2, which was 22.48% higher than the control ''Chaohongbaoshi No.2''. It was suitable for open field and cold shed cultivation in early spring in Guizhou.
