Abstract: The investigation revised the former classifcation of Armeniaca mume Sieb. and divided it into three types:the white, the yellow and the green. Fruits of each type with red halo color mightbe considered as a sub-type. Germ plasm characteristics such as initial fruitage time, mature period, blossom flower and the affinity of copulation between various types were described. The white tended to resist scab. Some of the yellow might bear fruit in four years. The yellow was a crossbreed of the white and the orange. Flower anatomy and pollination test showed Armeniaca mume in Da'yi had a higher reproductive capacity and kept some characters of the wild species. Ecological analysis hinted that the Armeniaca mume in Da'yi could adapt to higher moisture.
