2020), due to its major product (nearly 50% of dry kernel weight), tea oil, is an edible oil known as вЂњeastern olive oilвЂќ with high nutritional value and health benefits.

It has been cultivated in south-central and southern China for more than 2,000 years ( Zhu et al. oleifera), belonging to genus Camellia in the family Theaceae, originates from China and is one of the worldвЂ™s four major oil tree species (together with oil palm, olive and coconut) ( Chen et al. oleifera germplasms using the morphological and economic traits, together with SSR molecular marker, and the results allow us to find evidence for the origin of varieties, establish core breeding populations and its fingerprint.Д¬amellia oleifera Abel. This is the first report to evaluate the genetic diversity of different C. oleifera germplasms perform a rich genetic variation. The genetic similarity coefficients of SSR markers ranged from 0.05 to 0.91, and the germplasm materials were divided into five groups. Through the variation and cluster analysis of 17 morphological and economic traits, the germplasm was divided into a candidate core breeding group with higher economic traits and a core breeding group with higher morphological traits. oleifera using morphological and economic traits, as well as SSR molecular marker. In this study, we estimated the genetic relationship of 150 accessions of C. It is very helpful for the scientific utilization, cultivation and preservation of germplasm resources through evaluating the genetic diversity. oleifera) is a cultivable plant with important economic value.
