Abstract: 【Objective】To screen tomato varieties suitable for cultivation in Baotou City and its surrounding areas in Inner Mongolia.【Methods】Twenty-four nationally registered high-quality,disease-resistant tomato varieties,categorized into cherry tomatoes,taste tomatoes,and hard-fleshed tomatoes,were evaluated. A total of 24 indicators,including agronomic traits,nutritional quality,and yield,were measured. Principal component analysis was employed for comprehensive identification and evaluation.【Results】Among cherry tomatoes,the top two varieties based on comprehensive scores were Jingxing and Lvyangli,characterized by slightly concave fruit shoulders,two locules,and relatively high single fruit weights（52.65 g and 62.18 g,respectively）. These varieties exhibited a sweet-tart flavor,with Lvyangli achieving the highest yield of 4 464.67 kg/hm². For taste tomatoes,DRK0568 and Antelaisi were the top two varieties,with mature fruits color displaying pink coloration and high single fruit weights（277.01 g and 242.97 g,respectively）. These varieties had a sandy texture and tart-sweet flavor,with DRK0568 recording the highest yield of 6 835.66 kg/hm². Among hard-fleshed tomatoes,Daimeite FA2177 and TY196 ranked highest,both with pink mature fruit color and high single fruit weights（262.30 g and 238.39 g,respectively）. These varieties had a sandy texture and tart flavor,with relatively high yields of 6 720.33 kg/hm² and 6 829.67 kg/hm²,respectively.【Conclusion】The cherry tomato varieties Jingxing and Lvyangli,taste tomato varieties DRK0568 and Antelaisi,and hard-fleshed tomato varieties Daimeite FA2177 and TY196 are recommended as promising varieties for promotion and cultivation in Baotou City,Inner Mongolia.
