The traditional coffee breeding is a long process, due to the plant long life-cycle and it takes, in average, 25-30 years to create a new cultivar. Androgenesis allows the obtainment of new cultivars in one generation and the establishment of homozygous lines in a short period of time. In coffee, for instance, those periods could be reduced to 4 and 8-10 years. At Coffee Rusts Research Center (CIFC), the process of androgenesis in cultivars susceptible to coffee main diseases was optimized, namely in cvs Catuai and Cuturra. Further, it was applied to some progenies of Catimor and Sarchimor which presented some resistance to coffee leaf rust (Hemileia vastatrix) and to coffee berry disease (Colletotrichum kahawae). Some results concerning the culture of anthers/microspores of cvs Catuai and Catimor will be presented and discussed
