Abstract: 【Objective】 Select suitable processing tomato varieties suitable for cultivation in Aral,Xinjiang. 【Methods】 Nine processing tomato varieties were used as experimental materials.Twelve traits including plant height, stem diameter, leaf area, chlorophyll content, fruit shape index, single fruit weight, soluble solids, soluble sugar content, VC content, lycopene, total flavonoids content and soluble protein content of each variety were measured.Meanwhile, principal component analysis, membership function and cluster analysis were carried out. 【Results】 Four principal components including plant height, soluble solids, VC content and soluble sugar were extracted.The comprehensive scores of principal component factors of 12 traits were calculated by weighting the eigenvalues of principal components.The order from high to low was Q020 > Zaode > Jiayi 200 > Xinyin 98-1 > American Century Red > Ruby > Hongguo No.3 > Qilin Diamond > Jiahehongyun.Among them, the comprehensive evaluation value of Q020 was the highest, which was 0.770.The comprehensive evaluation value of Jiahehongyun was the smallest, which was 0.329. 【Conclusion】 Q020 has good growth indexes and good quality, which can be used as the main cultivar of processing tomato in Aral,Xinjiang.
