Resistance to Hemileia vastatrix in an Icatu population



Resistance to Hemileia vastatrix in an Icatu population



Garcia de Orta, Estudos Agronomicos 6(1/2): 19-24



Three Coffea arabica varieties and a C. canephora autotetraploid were the immediate ancestors of a diverse population designated Icatu, which showed great variability in morphology, agronomic characters and resistance to pests and diseases, including Hemileia vastatrix. Among 194 F2 and F3 plants from backcrosses to C. arabica varieties were 44 which were resistant to all 26 physiological races of H. vastatrix which were available for testing.
