| 摘 要： | 烟粉虱Bemisia tabaci(Gennadius)是由多种生物型或物种组成的复合种。Q型烟粉虱在我国部分地区正在取代B型烟粉虱成为优势生物型。烟粉虱Q型与B型遗传多样性比较研究为解析这2种生物型入侵的遗传学基础具有重要的意义。本文利用AFLP技术研究了Q型(包括Q1型、Q2型)、B型烟粉虱种群的遗传多样性。结果表明:Q型烟粉虱遗传多样性高于B型烟粉虱;Q1型烟粉虱各项遗传多样性指数均接近于Q2型。最后探讨了AFLP与SSR分子标记的各自特点。

| Abstract: | Bemisia tabaci（Gennadius）is a species complex comprised of many biotypes.Biotype Q is replacing biotype B to become the predominant biotype in parts of China.The comparison of genetic diversity between biotypes B and Q is important to comprehend the genetic basis of the two biotypes＇competition.The AFLP method was used to study the population genetic diversity of the Q1,Q2 and B biotype.The results show that the genetic diversity of biotype Q is higher than that of B,and that of Q1 similar to that of Q2.Finally,the characteristics of AFLP and SSR are discussed. |
