摘　　要：由于白芨的性状比较少,给种质资源综合评价带来了一定的难度,因此,采用灰色理论和Topsis法对白芨种质资源进行了综合评价,结果表明:灰色关联分析法与综合评价法的结论基本上是一致的,并与种质资源田间综合表现相符。但在灰色关联度对种质资源的评价中,因其灰色关联度的差异不是很大,不能很好地评价出种质资源的优劣,而Topsis法评价结果中Ci值差异十分明显,能更好地评价品种的优劣。Less bletilla tuber traits bring about a certain difficulty to the comprehensive evaluation of bletilla germplasm re- sources. Therefore, grey relation analysis method and Topsis method were used to comprehensively evaluate bletilla germplasm re- sources. The results indicated that the above two methods gave similar comprehensive evaluation results, which were in consistent with the field general performance of the tested germplasm resources. Because there were significant differences in Ci value of Topsis method, and no big differences in grey relation degree among various germplasm resources, Topsis method could better evaluate the performances of the tested germplasm resources.
