基于DTOPSIS法的日光温室大果番茄组合比较分析与评价

Comparative Analysis and Evaluation of Large Fruit Tomato Combinations in Solar Greenhouse Based on DTOPSIS Method

为选育出适于宁夏自治区秋冬茬日光温室种植的番茄新品种,在日光温室对57份大果番茄新组合进行了品种比较,通过调查植株性状、果实性状、番茄花叶病毒病病情指数和产量,并采用逼近理想解排序法(DTOPSIS法)对番茄单果质量、可溶性固形物含量、花叶病毒病病情指数和产量数据进行综合评价,结果表明:通过应用DTOPSIS法综合评价,排名前8的组合有53号、59号、58号、61号、46号、9号、60号、15号,说明这8个组合表现优良。抗花叶病毒病的病情指数、产量比较与综合评价得出的结果基本一致,而硬度和可溶性固形物含量的评价与应用DTOPSIS法综合评价的结果不一致,这说明日光温室秋冬茬番茄品种番茄花叶病毒病抗性和产量要求比可溶性固形物含量、果实硬度指标更重要,综合各指标得出:53号、59号、58号、61号是适合宁夏秋冬茬日光温室栽培的优良组合。

In order to breed new tomato cultivars suitable for solar greenhouse planting in autumn and winter in Ningxia,57 new tomato combinations with large fruit were compared in solar greenhouse.By investigating plant traits,fruit traits,disease index of tomato mosaic virus and yield,the data of single fruit weight,soluble solid content,disease index of tomato mosaic virus and yield of tomato were comprehensively evaluated by using DTOPSIS method.The results showed that the top eight combinations were No.53,No.59,No.58,No.61,No.46,No.9,No.60 and No.15 by applying DTOPSIS comprehensive evaluation,indicating that these eight combinations had excellent performance.The results of disease index of tomato mosaic virus and yield were basically consistent with those of comprehensive evaluation.The evaluation results of fruits hardness and soluble solid content were inconsistent with the comprehensive evaluation results of DTOPSIS,which indicated that resistance to mosaic virus and yield requirements of tomato cultivars in autumn and winter in solar greenhouse were more important than indexes of soluble solid content and fruit hardness.It was concluded that No.53,No.59,No.58 and No.61 were the excellent combinations suitable for solar greenhouse cultivation in autumn and winter of Ningxia.
