扁桃杧(Mangifera persiciformis}遗传多样性的AFLP分析
Genetic diversity of Biantaomang (Mangifera persiciformis) verified by AFLP marker
摘要
Abstract
Levels of genetic diversity within and among 8 natural populations of Mangifera persiciformis C.Y.Wu et T.L.Ming were analyzed by AFLP markers.A total of 612 fragments were generated from 8 pairs of selective AFLP primer combi-nation, 514 (83.99%) of which were polymorphic.Genetic diversity difference among populations was relatively high based on the percentage of polymorphic loci ranged from 68.20% to 80.70% ,effective number of alleles ranged from 1.429 to 1.570, Nei's gene diversity index ranged from 0.271 to 0.321, and Shannon' s information index ranged from 0.408 to 0.465.Genetic differentiation mainly occurred within populations.However, some genetic differentiation had occurred among popu-lations (G_(st)=0.139, φ_(st)=0.198)according to Nei's Gst value and analysis of molecular variance (AMOVA).The genetic distance among Mangifera persiciformis C.Y.Wu et T.L.Ming populations had a close relationship with the geographical distance according to UPGMA cluster analysis based on Nei's genetic distance.The Mantel test showed that genetic distance was positively correlated with geographical distance.关键词
