SRAP Analysis of Genetic Diversity in Orchardgrass

  title={SRAP Analysis of Genetic Diversity in Orchardgrass},
  author={Yu Yong-xiong},
The genetic diversity among 45 orchardgrass accessions was tested by SRAP.21 primer combinations were used and 438 bands were produced in SRAP,of which 363(82.08%) were polymorphic.The coefficient range of genetic similarity was 0.6248-0.966 with 0.7958 on average,which showed rich genetic diversity of orchardgrass germplasm,too.45 accessions could be divided into 4 main groups by cluster and principal component analysis,which not only revealed the geographical distribution of accessions but… CONTINUE READING
