The coffee is one of the most important products of the international market, however the time and money wasted in breeding programs are limiting factors for its improvement. However, the anther culture appears as a viable alternative for a short time period solution for this problem. This work aimed to obtain the double haploids production from anther cultures of the coffee plant (indirect androgenesis) aiming to optimize a protocol calluse induction. For this purpose, asseptic conditions of the flower budsand anthers were accomplished, folowed by inoculationin IC medium and the tissue were kept for eight weeks at 25ºC ± 1 in the dark. To induce callogenesis in anthers of the 'Acaiá Cerrado' there were tested 2,4-D (0, 1, 2 and 4 mg.L-1) x kinetin (0, 2, 4 and 8 mg.L-1) and 2,4-D (0; 0,5; 1 and 2mg.L-1) x AIB (0; 0,5; 1 and 2mg.-1) plus 2 iP (2 mg.L-1) concentrations and for the 'Rubi' 2,4-D (0, 1, 2 and 4 mg.L-1) x kinetin (0, 2, 4 and 8 mg.L-1) concentrations. It was observed that the highest percentage of callogenesis induction in anthers of the 'Acaiá Cerrado' was provenient from 2,4-D (2 mg.L-1) + kinetin (1,9 mg.L-1) and 2,4-D (0,86 mg.L-1) + AIB (1 mg.L-1)+ 2iP (2mg.L-1) combinations for 'Rubi' 2,4-D (1,9 mg.L-1) and kinetin (4 mg.L-1).
