Genetic diversity of loquat (Eriobotrya japonica) revealed using RAD-Seq SNP markers.

ABSTRACT: Loquat (Eriobotrya japonica) have originated in southeastern China and spread as a cultivated plant worldwide. Many of the loquat genetic resources collected internationally are of unknown origin, and their genetic background requires clarification. This study analyzed the genetic diversity of 95 accessions by using Rad-Seq SNP markers. Data analysis broadly classified loquat into three groups: (1) Japanese and Chinese cultivars and some Japanese strains (wild plants that are not used for commercial cultivation), (2) Vietnamese, Israeli, Greek, USA, and Mexican cultivars and strains, and (3) other Japanese strains. Group 2 is cultivated mostly outside of East Asia and was clearly distinct from the other groups, indicating that varieties of unknown origin with genetic backgrounds different
