摘要：

The aim of this study was to select high-yielding coffee progenies with resistance to coffee leaf rust for the State of Parana (Brazil). Field experiments in a randomized block design were carried out in Itaguaje and Congonhinhas. Yield, vegetative vigor and rust resistance of nine progenies of Arabic coffee and three check cultivars were evaluated. Many genotypes derived from "Sarchimor" and "Catucai" were susceptible. Three coffee genotypes of Sarchimor germplasm and the F-6 generation of genotype "Catuai x (Catuai x BA-10 coffee)" were selected to advance generations and are promising to become new cultivars for being higher-yielding than 'IAPAR 59' and 'Tupi IAC 1669-33' and having a large number of plants with complete rust resistance.
