摘　　要：DUS测试指南是开展植物特异性、一致性和稳定性测试的重要依据。笔者简单介绍了中国和UPOV梨品种DUS测试指南,比较了不同指南的主要内容,包括材料要求、测试设计、结果判定、测试性状、标准品种和技术问卷等,分析总结了不同指南的优缺点,探讨并展望了中国梨品种DUS测试指南研制的潜力,为我国进一步研制梨品种DUS测试指南提供参考和思路。Test guideline is the important basis for the test of distinctness, uniformity and stability. In this paper, the main contents of four different test guidelines for Pyrus L. were compared and analyzed,including material requirements, conducts of the tests, assessments of the test, test characteristics, example varieties and technical questionnaires. TG/169 is applied to the clonally propagated rootstock varieties of pear and was released in 2000. TG/15 is applied to scion varieties of P. communis L. and also was released in 2000. TG/149 is applied to the scion varieties of Pyrus pyrifolia（Burm. f.） Nakai var. culta（Mak.） Nakai（Syn. Pyrus serotina Rehd.） and is the earliest pear test guideline released on November4 th, 1994. NY/T 2231 is applied to the scion varieties of four species of pear as P. ussuriensis Maxim., P.bretschneideri Rehd., P. pyrifolia Nakai. and P. communis L. and was released in 2012. The quality of the materials required is the same but the forms and the numbers are different. TG/169 requires 25 oneyear-old rooted plants（virus free）. TG/149 requires 10 one-year-old grafted plants. TG/15 and NY/T2231 require grafted plants or shoots. TG/15 requires 5 grafted plants for varieties resulting from crossing and 10 grafted plants for varieties obtained from mutation, or 3（from crossing） or 10（from mutation） dormant shoots for grafting. NY/T 2231 requires at least 15 grafted plants or enough dormant shoots to propagate 15 trees. In the test conduct, test duration and test place of the four test guidelines are the same, but others are different. TG/15 and NY/T 2231 require all observations to be made on 5 plants or parts taken from each of 5 plants in the case of varieties resulting from crossing, and on 10 plants or parts taken from each of 10 plants in the case of mutants. TG/149 requires all observations to be made on 20 parts of plants, four from each of five plants. TG/169 requires all observations to be made on 10 plants or parts taken from each of 10 plants. In the four g
