(A) New Varieties and Planting Materials Five high-yielding new varieties of Hypericum rehmanniae 6 were bred in the 15-year time period of Baoting Hot Work in Guangdong Province, of which, Hetan 3 showed high-yielding early-maturing and high yield, moderate cold tolerance and good traits , The mother is a million 2-31 × day any 31-45, the father is Cangchang 20-7 × White Nan 7-33.
