摘要
以47个番茄杂交组合为研究对象,基于23个数量性状,采用4种评价方法对宁夏露地番茄适应性进行综合评价。结果表明:23个数量性状间存在显著或极显著相关性;以特征值大于1提取出9个主成分,累计贡献率达77.341%;在灰色局势决策法、DTOPSIS法、灰色关联度及多元统计法共4种评价方法中,23ZJ05均处于前10,其相关系数分别为0.799 8、0.790 4、0.657 7、0.612 0;23ZJ28在灰色局势决策与灰色关联度评价中均排名第1,其相关系数分别为0.836 3、0.696 2;23ZJ15在DTOPSIS法评价中排名第1、在多元统计法评价中排名第2,其相关系数分别为0.834 9、0.701 8;各评价方法对番茄杂交组合评价结果可靠性的综合表现由高到低依次为灰色局势法的综合量化优势值、DTOPSIS的相对贴近度、灰色关联度的加权关联度、多元综合评价值。23ZJ05、23ZJ28、23ZJ15是综合表现优良的番茄杂交组合,灰色局势决策法在评价番茄杂交组合的结果可靠性更高。
Total of 47 tomato hybrid combinations were used as the research objects,based on 23 quantitative traits,and four evaluation methods were used to comprehensively evaluate the adaptability of Ningxia open field tomato.The results showed that significant or highly significant correlations existed among the 23 quantitative traits;nine principal components were extracted with eigenvalues greater than 1,and the cumulative contribution rate reached 77.341%;in four evaluation methods,including the gray situation decision-making method,the DTOPSIS method,the gray correlation degree,and the multivariate statistical method,the 23ZJ05 were in the top 10,with correlation coefficients of 0.7998,0.7904,0.6577 and 0.6120,respectively;the 23ZJ28 ranked the first in both gray situation decision-making and gray correlation,and its correlation coefficient reached 0.8363 and 0.6962,respectively.The 23ZJ15 ranked the first by DTOPSIS method and the second by multivariate method,and its correlation coefficient reached 0.8349 and 0.7018,respectively.Comprehensive evaluation of the reliability of tomato hybrid combination evaluation results using various evaluation methods,the order from high to low was the comprehensive quantitative advantage value of the grey situation method,the relative closeness degree of DTOPSIS,the weighted correlation degree of grey correlation degree,and the multiple comprehensive evaluation value.The 23ZJ05,23ZJ28,23ZJ15 were tomato hybrid combinations with excellent comprehensive performance,and the gray situation decision-making method was more reliable in evaluating the results of tomato hybrid combinations.
