Eighteen progenies in the F5 generation of the H 419 hybrid were studied, proceeding from the crossing between the Híbrido deTimor (UFV 445-46) and the IAC 30 Catuaí Amarelo (UFV 2143), 5 progenies in the F5 generation of the H 516 hybrid, proceeding from the crossing between the Híbrido deTimor (UFV 446-08) and the IAC 86 Catuaí Amarelo (UFV 2154) and the IAC 44 the red Catuaí (UFV 2144) as control, with and without rust control. Regarding the production of cherry coffee by plant and with the rust attack, the H419-3-1-1-14 and the H516-2-1-1-18, progenies were the ones that showed greater productivity and rust resistance (grade 0), followed by the H419-6-3-6-12, but with partial rust resistance . These progenies were, also, the ones that showed greater length of the plagiotrophycal spreads, where influenciated in 37.73% (R²) at production of cherry coffee by plant. The plagiotrophycal spread's length, fust diameter and plants height were the most correlated attributes r = 0.5977, r = 0.3316 and r = 0.2848, p < 0.01 respectively, with these progenies productivity, according results obtained by Dhaliwal (1968). Regarding to the Hemileia vastatrix Berk. et Br. fungus resistance, the progenies showed herdability on the wide-high way (h a² = 0,80 between and h a² = 0,96 between and inside the progenies), pointing them as resistant and with a high genetic variability for selection of resistant material to the coffee rust.
