Partial resistance to fruit necrosis associated to Colletotrichum spp. among arabic coffee genotypes. Brazilian Archives of Biology and Technology, Curitiba, v. 50, n. 3, p. 395-402, may 2007.1678-4324https://doi.org/10.1590/S1516-89132007000300005sbicafe.ufv.br/handle-server/123456789/14857The aim of this study was to evaluate the resistance to fruit necrosis associated to Colletotrichum spp. in Coffea arabica L.. Twenty-two arabic coffee genotypes were performed in a randomized block design, with three replications and ten plants per plot. They were evaluated for the variables fruit necrosis, luminosity index inside of the plant canopy and fruits per productive nodes of the plants. There was genetic variability for the resistance to fruit necrosis. Different partial resistance levels, varying from highly susceptible (score = 3.89) to moderately resistant (score = 1.77) were observed. The genotypes that presented moderate resistance were the cultivars IPR-100, IPR-103, IPR-105 and IPR-108 and the coffee selection IAPAR-00023.pdfenOpen AccessAntracnosisCoffea arabicaCoffee breedingColletotrichum gloeosporioidesCultivarsFitossanidadePartial resistance to fruit necrosis associated to Colletotrichum spp. among arabic coffee genotypesArtigo
