%X Monoembryony was observed in polyembryonic mango cultivars Tu-mang, Carabao and Aroemanis, the frequencies of monoemhryony being 1.04%, 3.85% and 5.44%, respectively. Two- to 6-embryonic cultivars appeared in Tu-mang, and 2- to 8-embryonic cultivars in Aroemanis. The morphology of cotyledons and the location of radicles in polyembryonic seeds varied with the cultivars. Germination rate and seedling survival rate of polyembryonic cultivars were negatively related with the increase of the number of embryos. Somatic chromosome number ofpolyembryonic seedlings was 2n=40, and no change in chromosome number was observed. Peroxidase analysis showed that variation existed among polyembryonic seedlings from the same seed.
