中文摘要	为提高木本粮油植物掌叶木不同种源种子及籽油性状的综合评价结果准确性和评价方法的优选,指导掌叶木优良种源筛选和良种选育,该文构建了-套综合评价模型,对广西乐业、田林、凤山和环江以及贵州独山5个种源掌叶木种子及籽油相关的14项指标采用主成分分析法、因子分析法、离差最大法、熵值法4种单-方法进行评价排序,并对4种方法的评价结果采用均值、Borda、Copeland共3种组合方法进行评价排序,均通过肯德尔和谐系数一致性检验后确定最终评价排序;采用斯皮尔曼等级相关系数对最终评价排序与4种单-方法评价排序进行相关性分析,并筛选最好单-评价方法。结果表明:4种单-评价方法下种源排序虽存在一定差异但通过了肯德尔和谐系数一致性检验;3种组合评价排序均相同,各种源最终评价排序从高到低依次为凤山、乐业、独山、环江、田林。最终评价排序与主成分分析法、因子分析法、离差最大法和熵值法等4种单-方法评价排序的斯皮尔曼等级相关数值分别为1.00、0.90、1.00、0.90,相关性均达到显著水平(P <0.05);主成分分析法和熵值法所得种子千粒质量的权重值均列各指标首位。因此,基于4种单-评价方法和3种组合评价方法的综合评模型为多种源掌叶木种子及籽油性状提供更为科学合理的排序结果;从易用、简便和有效性角度,掌叶木种子及籽油性状的最优单-评价方法为熵值法,评价中最重要的指标为种子千粒质量,凤山种源掌叶木种子及籽油性状最优。研究结果可为掌叶木种质资源高效利用提供理论依据,也可为种子及油脂领域综合评价研究提供新思路。
英文摘要	Handeliodendron bodinieri was a rare and endangered endemic single species genus plant only in karst areas of southwestern China,and it was also an excellent species of rocky desertification control,furthermore,its seed oil had higher value in nutrition,health care and industry.However,due to the lack of recognition of the related traits of H.bodinieri germplasm resources,the planting and popularization of H.bodinieri was restricted to some extent.Therefore,it was necessary to scientifically evaluate seed and seed oil traits of H.bodinieri from different provenances in order to guide the selection of good provenance and breeding.To improve the accuracy of evaluation results and optimum selection evaluation method,a new comprehensive evaluation model was constructed in this study.Fourteen indices related to seed and seed oil of H.bodinieri including seed length,seed diameter,single seed weight,1 000- grain weight of seed,seed kernel rate,seed oil content,unsaturated fatty acid compositions of seed oil and so on were selected and determined.Five provenances of Leye of Guangxi,Tianlin of Guangxi,Fengshan of Guangxi,Huanjiang of Guangxi and Dushan of Guizhou were evaluated and sorted by four single evaluation methods of principal component analysis,factor analysis,maximizing deviation method,entropy weight method.The evaluation results of four single methods above were evaluated and sorted by three combination evaluation methods of mean,Borda and Copeland.Final evaluation rank was determined after all these methods had passed the Kendall’s coefficient of concordance test.Spearman rank correlation coefficient was used to analyze the correlation between the final evaluation rank and four single methods evaluation ranking,and the best single evaluation method was selected at last.The results are showed following:Although there are some differences in the ranking of provenance evaluation in four single evaluation methods,they have passed the Kendall’s coefficient of concordance test;all the three combination methods evaluation rank values are the same.Final evaluation ranking of provenance from high to low is Fengshan of Guangxi,Leye of Guangxi,Dushan of Guizhou,Huanjiang of Guangxi and Tianlin of Guangxi.Spearman rank correlation coefficient between final evaluation ranking and evaluation ranking of principal component analysis,factor analysis,maximum deviation method and entropy weight method are 1.00,0.90,1.00 and 0.90 respectively,and all correlations have reached a significant level (P <0.05);the weight value of 1 000 - grain weight of seed obtained by principal component analysis and entropy weight method is listed in the first place of all indices.Therefore,the comprehensive evaluation model based on four single evaluation methods and three combination evaluation methods can provide scientific and reasonable ranking results for the seed and seed oil traits of H.bodinieri in multiple provenances.From the perspective of ease,convenience and effectiveness,the entropy method is the optimal single evaluation method for seed and seed oil traits of H.bodinieri,the most important index in the evaluation is 1 000 - grain weight of seed,and seed and oil traits of H.bodinieri in Fengshan of Guangxi provenance are the best.The research results provide a theoretical basis for efficient utilization of germplasm resources of H.bodinieri,and it also provides a new idea for the comprehensive evaluation of seed and oil field.
