Item IPR Alvorada – Dwarf Arabica coffee cultivar with high yield(Crop Breeding and Applied Biotechnology, 2024-09-25) Sera, Gustavo Hiroshi; Sera, Tumoru; Mariucci Junior, Valdir; Harumi, LucianaIPR Alvorada is a Coffea arabica cultivar with C. canephora introgression, developed from a cross between IAPAR 59 and Mundo Novo IAC 376-4. This cultivar has a dwarf-medium size, high yield, good cup quality, strong vegetative vigor, a medium fruit ripening cycle, and slight resistance to coffee leaf rust.Item Selection of Arabic coffee progenies with rust resistance(Crop Breeding and Applied Biotechnology, 2014-06) Shigueoka, Luciana Harumi; Sera, Gustavo Hiroshi; Sera, Tumoru; Fonseca, Inês Cristina de Batista; Mariucci Junior, ValdirThe aim of this study was to select high-yielding coffee progenies with resistance to coffee leaf rust for the State of Paraná (Brazil). Field experiments in a randomized block design were carried out in Itaguajé and Congonhinhas. Yield, vegetative vigor and rust resistance of nine progenies of Arabic coffee and three check cultivars were evaluated. Many genotypes derived from “Sarchi- mor” and “Catucaí” were susceptible. Three coffee genotypes of Sarchimor germplasm and the F 6 generation of genotype “Catuaí x (Catuaí 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.Item IPR 107 – Dwarf arabic coffee cultivar with resistance to coffee leaf rust(Crop Breeding and Applied Biotechnology, 2013-10) Sera, Tumoru; Sera, Gustavo Hiroshi‘IPR 107’ was derived from a cross between ‘IAPAR 59’ and ‘Mundo Novo IAC 376-4’. ‘IPR 107’ is a dwarf medium size plant with medium precocity in ripening and with complete resistance to rust races in this time. This cultivar presents superior quality and high yield in many coffee regions.
