SRAP是一种简单有效的标记技术，在检测遗传多样性方面比其他分子标记技

SRAP marker is a simple and effective technique in the detection of genetic diversity reliable than other molecular markers [34]. In this study of 225 pairs of SRAP primers were screened on 10 154 samples primers Pterospermum 17 populations were amplified genetic diversity of bands 179, 179 are polymorphism and the rate of up to 100 %, indicating that this selection of 10 pairs of primers can provide reliable information, as research Pterospermum endangered plant genetic diversity. The dominant marker PIC value of 0 to 0.5, where 0 represents a fixed allele, 0.5 allele frequency equal to [27]. In this study, the PIC SRAP marker range from 0.454 to 0.498 of an average of 0.473, but also indicates the presence of genetic diversity Pterospermum groups, which can develop SRAP primer abundant polymorphism, analysis shows the study of the sample differences between.

SRAP is a simple and effective marking technique that is more reliable than other molecular marker strains in detecting genetic diversity. This study screened 10 primers from 225 sraps to 154 samples of 17 populations of semi-maple load, expanding 179 bands, 179 were polymorphic, polymorphic up to 100%, indicating that the 10 pairs of primers selected could provide reliable information. Used as a study of genetic diversity of rare and endangered plants semi maple load. The PIC value of the dominant marker is 0 to 0.5, where 0 indicates that an allele is fixed and 0.5 indicates that alleles have equal frequencies. In this study, the PIC values of SRAP markers ranged from 0.454 to 0.498 with an average of 0.473, indicating that there was a wealth of genetic diversity in the semi-maple population, and that these SRAP primers could develop rich polymorphisms, indicating the differences between the analyzed samples in this study.

SRAP is a simple and effective marker technology, which is more reliable than other molecular marker technologies in detecting genetic diversity [34]. In this study, 154 samples from 17 populations of p.semiliquidambar were screened by 10 pairs of SRAP primers, 179 bands were amplified by genetic diversity analysis, 179 of which were polymorphic, and the polymorphic rate was as high as 100%, indicating that the 10 pairs of primers selected can provide reliable information for the genetic diversity study of p.semiliquidambar. The pic value of dominant marker is 0-0.5, in which 0 represents an allele fixation and 0.5 represents an allele frequency equal [27]. In this study, the pic values of SRAP markers ranged from 0.454 to 0.498, with an average of 0.473, which also showed that there was a rich genetic diversity in the population of Schima superba, and these SRAP primers could develop a wealth of polymorphism, showing the differences between the samples analyzed in this study.<br>
