Fingerprints of 8 Varieties of Corylus heterophylla×Corylus avellana Based on SSR Markers

C. heterophylla×C. avellana is the main variety of Corylus genus applied in China. In this paper, 9 SSR markers were used to analyze population genetic diversity and to establish the fingerprints of the introduced 8 varieties of C. heterophylla×C. avellana. The results showed that the mean numbers of the effective alleles, observed heterozygosity, and expected heterozygosity were 4.161, 0.875, and 0.734 respectively, showing a higher degree of population genetic diversity. And with eight marker combinations between Ch4-7 and Ch8-9, 8 varieties could be efficiently determined, which established the foundation of protection and application of C. heterophylla×C. avellana.
