[Resistance of potato genotypes to Potato leafroll virus and to Potato virus Y]
Horticultura Brasileira 22 (3), 521-524
Abstract: Potato leafroll virus (PLRV) and Potato virus Y (PVY) are the main causes of degeneration of potato seeds in Brazil. The field resistance of potato genotypes to these viruses was evaluated in Rio Grande do Sul State, Brazil, of 20 clones and cultivars, during three consecutive spring cropping seasons. Virus detection was carried out by serological tests (DAS-ELISA). Using the grouping analysis, the genotypes were separated in three groups for PLRV resistance (Elvira, Achat, Bintje, Monalisa, Monte Bonito, Panda and Araucária, resistant; Baronesa, Asterix, Atlantic, 2CRI-1149-1-78, C-1226-35-80, Astrid, C-1714-7-94, A-1139-12-92, Macaca, Eliza and Santo Amor, susceptible; Catucha and Cristal, very susceptible) and in four groups for PVY resistance (Asterix, Astrid, Catucha, Cristal, Macaca, Monte Bonito, A-1139-12-92, C-1226-35-80 and C-1714-7-94, resistant; Baronesa, Santo Amor, Monalisa, Panda and 2CRI-1149-1-78, intermediate resistance; Bintje, Atlantic, Elvira and Araucária, susceptible; Achat and Eliza, very susceptible).
