Different fungi species of the Colletotrichum have been reported as causing disease in coffee crop in Brazil. The aim of this research was to estimate the correlation coeficient among Colletotrichum spp. incidence with some coffee agronomic traits. F2 progenies of 'IAPAR-59' x ("Icatu" x "Catuaí") and 'IAPAR-59' x 'Mundo Novo IAC 376-4' were evaluated at IAPAR´s experimental station at Londrina, Paraná State, Brazil, in experiment installed in may 1997, by using spacing 2,5 x 0,5 m. The experimental design used was randomized blocks with 56 treatments, two replications and 10 plants per plot. The vegetative vigor, fruits maturation and plant stature traits were evaluated in may 2000. The Colletotrichum spp. occurrence was evaluated in December 2001. Subjective scores performed these evaluations. The Colletotrichum spp. occurrence, fruits maturation and plant stature scores were attributed from 1 to 5, where 1 was given for no lesions, late maturation and small stature, respectively. The score for vegetative vigor ranged, from 1 to 10, and 10 was for the more vigorous plants. The genotypic correlations estimated between the Colletotrichum spp. and maturation precocity, plant stature and vegetative vigor were, respectively, +0,80, +0,89, -0,92. These results suggest that the Colletotrichum spp. occurrence is highest in coffee plants with early ripening, higher stature and low vegetative vigor.
