Genetic Diversity of Tea Plant (Camellia sinensis (L.) Kuntze) Germplasm Resources in Wuyi Mountain of China Based on Single Nucleotide Polymorphism (SNP) Markers

Wuyi Mountain in Southeast China is the origin of black tea and oolong tea. It also considered ‘treasure trove cultivars’ because its rich germplasm resources. In present study, population structure genetic diversity 137 germplasms from adjacent areas were analyzed by SNPs. The information index (I), observed heterozygosity (Ho), expected (He) fixation (F) polymorphisms selected SNPs high, stable reliable. Ho had an average 0.389, while He 0.324, indicating that diversity. AMOVA results showed variation came mainly intrapopulation variation, accounting for 66% total variation. differences Fst Nei values between are similar to geographical differences. Multiple analyses based on high-quality found landraces plants different backgrounds wild-type underwent differentiation. This study provides a basis effective protection utilization lays foundation identifying potential parents optimize cultivation.
