Study on Comprehensive Evaluation of New Strains of Processing Tomato Based on the Grey Correlation Analysis

[Objective] The aim was to select new strains of processing tomato with good comprehensive traits.[Method] Ten new strains of processing tomato was selected to carry out varieties comparative test,the determination indices were growth period,yeild and indoor physical and chemical indicators.[Result] 20040812's fruit traits was good,processing traits was middle,lycopene content and yield was high,and yield was higher 8.3 % than that of control,so its comprehensive traits was good;98D51×Jiahe No.9's plant height and processing traits was middle,yield was low,while its comprehensive traits was the best,nearest to the ideal variety.[Conclusion] 98D51×Jiahe No.9 and 20040812 can join into the next variety regional test.
