    Resistance to bacterial halo blight in Arabica coffee lines derivative from the genotype C1195-5-6-2 under natural infection conditions
    (Crop Breeding and Applied Biotechnology, 2018) Andreazi, Elder; Sera, Gustavo Hiroshi; Sera, Tumoru; Fonseca, Inês Cristina de Batista; Shigueoka, Luciana Harumi; Santos, Willian Gabriel dos; Pereira, Carlos Theodoro Motta
    The aim of this study was to identify resistance to bacterial halo blight in Arabica coffee lines carrying Coffea racemosa genes. Eighteen Arabica coffee lines derivative from the genotype C1195-5-6-2, and the cultivars IAPAR 59 and IPR 99 were evaluated for resistance to bacterial halo blight in two trials carried out in field conditions, in Londrina, PR, Brazil. The cultivars Mundo Novo IAC 376-4 and Catuaí Vermelho IAC 81 were included as susceptible controls. Ten lines and the cultivar IAPAR 59 showed resistance to bacterial halo blight. The cultivar IPR 99 presented intermediate reaction, and the controls were very susceptible. This is the first study to show that lines derivative from the genotype C1195-5-6-2, which has C. racemosa genes, could be a source of resistance to bacterial halo blight in coffee breeding programs.

    IPR 106: new Arabica coffee cultivar, resistant to some Meloidogyne paranaensis and M. incognita nematode populations of Paraná
    (Crop Breeding and Applied Biotechnology, 2020) Sera, Gustavo Hiroshi; Machado, Andressa Cristina Zamboni; Ito, Dhalton Shiguer; Shigueoka, Luciana Harumi; Silva, Santino Aleandro da; Sera, Tumoru
    Cultivar IPR 106 resulted from a spontaneous hybridization between “Icatu IAC 925” and an unknow dwarf plant. It is a dwarf cultivar with high rusticity, late ripening cycle, large grains, excellent cup quality and resistance to some populations of the nematodes Meloidogyne paranaensis and M. incognita found in the state of Paraná.

    IPR 103 – Rustic dwarf arabic coffee cultivar more adapted to hot regions and poor soils
    (Crop Breeding and Applied Biotechnology, 2013-03) Sera, Tumoru; Sera, Gustavo Hiroshi; Fazuoli, Luiz Carlos
    ‘IPR 103’ was derived from a cross between “Catuaí” and “Icatu”. ‘IPR 103’ is a medium size dwarf cultivar with high rusticity, partially resistant to coffee leaf rust with late ripening. This cultivar is more adapted to hot regions and poor soils. It presents partial resistance to necrosis and mummification of young fruits on field conditions. Key words: Breeding, Coffea arabica, partial rust resistance.
