运用14个SCAR标记引物对松材线虫病马尾松(Pinus massoniana)抗性候选个体开展MuPS(MultiplexPCR of SCAR markers)分析。结果表明，120个样品中出现104个不同的MuPS型，区分率86.7%、74.2%的个体完全能够被识别。引物Pmscar157、Pmscar007、Pmscar053的多态位点数出现率非常高，分别占总位点数的131%、13.3%、18.4%，而引物Pmscar039、Pmscar499的位点数出现率非常低，分别占总位点数的0.16%、048%。因引物重复性高、稳定可靠，可通过获得的MuPS型识别抗性候选个体、管理抗性候选家系。

Using 14 SCAR marker primers to analyze the resistance seedlings of Pinus massoniana which resist Bursaphelenchus xylophilus. The results indicated that there were 104 different types of MuPS among those 120 samples, which could distinguish 86.6% samples, and 74.2% samples identified completely. Some primers such as Pmscar157, Pmscar007 and Pmscar053 produced more bands, which was 13.1%, 13.3%, 18.4% of the total bands respectively, while the primers Pmscar039 and Pmscar499 produced less band, and they were 0.16% and 0.48% of the total bands respectively. The primers used in this paper could fingerprint well because of high stability and reliability. Therefore, the attained MuPS could be used to identify and manage the resistance individual and the resistance family of P.massoniana.
