基于灰色关联度的加工番茄新品系综合评价研究

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

[目的]筛选综合性状优良的加工番茄新品系。[方法]选用10个加工番茄新品系进行田间品种比较试验,测定其生育期、产量、室内理化指标。[结果]20040812果实性状好,加工性状中等,番茄红素含量较高,产量高,较对照增产8.3%,综合性状好;98D51×佳禾9号株高适中,加工性状中等,产量较低,但综合性状最好,最接近理想品种。[结论]98D51×佳禾9号、20040812可以进行下一步的品种区域化试验。

[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.
