Abstract

Dear Editor,

The Chinese bayberry (Morella rubra Lour., 2n = 2x = 16) is an evergreen fruit tree native to southern China and the only domesticated species in family Myricaceae [1]. Today M. rubra is widely cultivated in subtropical regions of China and has become an economically important fresh fruit with >300 varieties and an annual production of 1.5 million tons [2, 3]. The aim of the current study was to reveal the domestication history of M. rubra using restriction site-associated DNA sequencing (RAD-seq) data. Seventy-eight individuals were sampled, including 44 landraces and improved cultivated varieties, 19 wild individuals from the natural distribution ranges in southern China, 14 from five other Morella species, and 1 from Comptonia.
