Abstract：The genetic diversity of 3 Deutzia baroniana populations from Shandong Province was studied by sequence-related amplified polymorphism ( SRAP) .The main research results were as follows .Two hun-dred and forty four loci were identified with 15 SRAP primer combinations , and in which , 167 were polymor-phic ones.The proportion of polymorphic loci ( PPL) was 68.44%.The Nei’s gene diversity index ( H) was 0.2158, and Shannon’s information index(I)was 0.3282, which showed rich genetic diversity in Deutzia ba-roniana.The coefficient of genetic differentiation (Gst) was 0.3685, which suggested that the variation among populations occupied only 36.85%and was much lower than that in populations .At the level of populations , Laoshan population contained the highest genetic diversity , while Culaishan population had the lowest .The Nei’s genetic identity ( GI) and genetic distance ( GD) between populations were 0.8350 ~0.8884 and 0 .1184~0 .1803 respectively , and the genetic distance between populations was not directly related to geo-graphical location .
