Abstract: The Pollen grains of 10 cultivars of Mangifera indica were examined by light micro- scope (LM) and scanning electron microscope (SEM). Their shapes, sizes and exine sculptures were compared. The result showed that the pollen shapes and exine sculptures among cultivars are different in varying degrees, which can be used to differentiate various cultivars. Sannianmang, Yuanjian xiangya, Hubaoya, Hongxiangya, Maqiesu, Yexiangmang, Daqingpi and Huangpi-datoumang are similar in exine sculpture, which shows these cultivars have close rela-tionship. Sankelimang has different exine sculpture from above cativars. Huongguang No.6' sculp-ture is between Sankelimang and the above eight cultivars.
