Abstract：To enrich the germplasm resources of Solanaceae in Baoshan area,excellent rootstocks with high yield,high grafting affinity and strong disease resistance,this study used 12 tomato grafting combinations to analyze the difference,grey correlation degree and comprehensive evaluation of seedling traits,fruit traits,disease resistance and yield.The results showed that there were abundant differences among the main characters,and the difference coefficient of vitamin C content was the largest.There were varying degrees of correlation between each trait and yield per plant.The top three traits in terms of correlation degree were the number of fruits per plant,seedling stem diameter,and seedling dry weight.The comprehensive evaluation concluded that'2022-5'+'Haomai 520','2022-2'+'Haomai 520','2022-5'+'Fenbeili 9'performed better,'2022-5'and'2022-2'were selected as rootstocks,which could achieve high yield,high grafting affinity and high disease resistance of grafted tomatoes,and were suitable for planting and promotion in Baoshan area.
