Cassava is the main staple crop in the tropics. It is vegetatively propagated by stem cuttings that maintain superior genotypes, but favors disease accumulation. In this report we present the results of the screening of the progeny and the second generation of the clone UnB 307 for apomixis using microsatellites. A total of 29 plants were screened, representing the maternal plant, its first and second generations, that were left to open pollination. About 20% of the offspring were rated as genetically identical plants. This result confirms the facultative apomictic nature of cassava, with high environment effect.
