Abstract: In this paper the meiosis of 9 species in genus Camellia were studied . C. chrysantha, C. impressinervis, C. pitardii var. pitardii, C. albovilosa and two population of C. saluenensis from Jindian of Kunming and Hekou of Baoshan, Yunnan formed 15 bivalents at metaphase I; C. pitardii var. yunnanica, c. yuhsienensis and five red-flowered populations of C. reticulata from Yunhua of Tengchong formed 45 bivalents at metaphase I. All of these species or populations mentioned above were pure, and might be used as the appropriate materials for purpose of breed-ing by crossing.
