| Abstract | This research aimed to identify the existence of genetic variability and demonstrate the influence of other variables for reaction to the cercosporiose through correlation and path analysis, searching variables for indirect selection. This study was carried out in an experiment constituted by progenies in selection for rust resistance, installed in Mococa, in randomized complete block design, 3 replications, 5 plants/plots. Evaluations for vegetative vigor (VV), production (Pr) and cercosporiose reaction (RC) were carried out before the harvest of 2006. Leaf nutritional analyses had been carried in each plot. The results indicated that vegetative vigour and yield should be considered in the selection of progenies that are more resistant to cercosporiose. The germoplasm "Catuai Sh3" and "Icatu x Catuai" can be important offspring of resistance or tolerance to cercosporiose. Stable and sufficient nutrition can cause induced resistance to cercosporiose. Key-word: genetic breeding, Cercospora coffeicola, indirect selection, induced resistance, vegetative vigour. |
