Rice grains, supposed to date back to about 3,000 years ago at Den Citadel relic site in Hanoi’s Me Linh District, are in fact a current rice variety, scientists said at a seminar held by the Agricultural Genetics Institute on Tuesday.

AND analysis indicates that the rice grains are completely similar with Khang Dan, a current rice variety, said Dr. Luu Minh Cuc from the institute.

Vietnamese archaeologists found the rice grains at the Den Citadel relic site in May.

Thanh Den is a well-known Vietnamese archaeological site. Seven excavations have taken place at the site since 2001.
