摘　　要：番茄杂交组合的综合评价是番茄育种的基础,为了提高番茄杂交组合的利用率和育种选育的水平,目前亟需一套科学合理的评价方法.研究基于30个表型性状对前期配组的529个大果番茄杂交组合进行描述性统计分析、主成分分析和综合评价.结果表明,9个植物学性状变异系数的范围为6.11%~41.90%,最大的是熟性,最小的是叶脉颜色;21个果实性状变异系数的范围为6.51%~41.22%,最大的是果顶形状,最小的是果实纵径;提取的8个主成分累计贡献率为63.07%,包含了组合表型性状的大部分遗传信息.在材料变异丰富的基础上,采用主成分分析和模糊隶属函数相结合的方法,对番茄杂交组合进行综合评价,筛选出综合表现较为优异且同时优于对照品种的前10个杂交组合的排名依次为ZJ093、ZJ075、ZJ492、ZJ118、ZJ487、ZJ094、ZJ494、ZJ355、ZJ496、ZJ414.以上研究为今后宁夏大果番茄杂交组合的选育提供理论依据和技术支撑.The comprehensive evaluation of tomato hybrid combinations is the basis of tomato breeding.In order to improve the utilization rate of tomato hybrid combinations and the level of breeding selection,a scientific and reasonable evaluation method is urgently needed.Based on 30 phenotypic traits,descriptive statistical analysis,principal component analysis and comprehensive evaluation of 529 large-fruit tomato hybrid combinations in the previous matching group were conducted.The results showed that the variation coefficients of 9 botanical traits ranged from 6.11%to 41.90%,which indicated that the largest was ripeness varied the most while the leaf vein color varied the lest;the variation coefficients of 21 fruit traits ranged from 6.51%to 41.22%,and the largest was fruit top shape,the smallest was the longitudinal diameter of the fruit;the cumulative contribution rate of the eight principal components extracted was 63.07%,which contained most of the genetic information of the combined phenotypic traits.On the basis of abundant material variation,the method of combining principal component analysis and fuzzy membership function was used to comprehensively evaluate the tomato hybrid combinations,and the top 10 hybrid combinations with the best comprehensive performance and at the same time better than the control varieties were ranked in order:ZJ093,ZJ075,ZJ492,ZJ118,ZJ487,ZJ094,ZJ494,ZJ355,ZJ496,ZJ414,which provided theoretical basis and technical support for the selection and breeding of Ningxia large fruit tomato hybrid combinations in future.
