Polymorphic Analysis of Crisp Peach Germplasm by Molecular Biology
The genomic DNAs of 17 accessions of crisp peach (Prunus persica var.vulgaris) were amplified by RAPD (Randomly Amplified Polymorphic DNA) with 22 primers selected from 200 arbitrary 10 decamer primers. Analyzing phylogenetic relationship through cluster of the bands in 180 amplified loci. The experimented accessions could be divided into five groups. Molecular checking index and conservation of key germplasm which included 6 cultivars,namely Dahongpao,Wuyuexian, Qinglingdongtao, Yixianhong, Yangquanroutao, Datiantao,were put forward according to their special bands.
