title: Genetic diversity assessment ofVitis ficifoliaBge. populations from Henan province of China by SRAP markers.
abstract: Eighteen sequence-related amplified polymorphism (SRAP) primer combinations were used to assess the genetic diversity of 126 individuals from five different geographical populations ofVitis ficifoliaBge. The numbers of bands scored per primer combination ranged from 8 to 27, with an average of 18.6 bands. At the population level, the percentage of polymorphic bands (PPB), Nei's gene diversity index (H) and Shannon's information index (I) were the highest in the Shihe (Xinyang) population (77.31%, 0.1987, 0.2805) and the lowest in the Linzhou (Anyang) population (55.82%, 0.1112, 0.1727). At the species level, PPB,HandIwere 80.56%, 0.2129 and 0.3075, respectively. The genetic differentiation coefficient (GST) was 0.2055 and the gene flow (Nm) was 1.9328, indicating strong intra-population genetic differentiation. Based on the unweighted pair group method based arithmetic average clustering diagram, the five studied populations may be divided into three groups. The clustering results were almost in accordance with the populations' geographical distribution.
