Of 63 local papaya varieties collected from Lai Chau, Dien Bien, Son La, Quang Ninh, Gia Lai, Tien Giang, and So Trang provinces, 10 varieties with some specious characteristics had been evaluated in Gialam- Hanoi during the period of 2008 - 2010. An F1 hybrid papaya variety (Hong Phi) was used as control variety. The study had evaluated a number of criteria as growth, yield, fruit quality of these local varieties and sexual expression at S12 autogamous population generation. The results showed that at S1 generation of autogamous population, hybridizations of hermaphrodite flower x hermaphrodite flower and female flower a hermaphrodite flower for autogamous population without male plants; hybridization of hermaphrodite flower a male flower expressed all types of plant.
