O vírus do enrolamento da folha da batata (Potato leafroll virus, PLRV) e o vírus Y da batata (Potato virus Y, PVY) constituem as principais causas da degenerescência da batata-semente no Brasil. Com o objetivo de determinar, nas condições do Rio Grande do Sul, a resistência de campo de genótipos de batata à infecção por estes vírus, avaliaram-se, na presença de infectores, durante três plantios consecutivos de primavera, 20 cultivares e clones de batata. A detecção dos vírus foi efetuada por meio de testes sorológicos (DAS-ELISA). Pela análise de agrupamento os genótipos foram separados em três grupos para resistência ao PLRV (Elvira, Achat, Bintje, Monalisa, Monte Bonito, Panda e Araucária, resistentes; Baronesa, Asterix, Atlantic, 2CRI-1149-1-78, C-1226-35-80, Astrid, C-1714-7-94, A-1139-12-92, Macaca, Eliza e Santo Amor, suscetíveis; Catucha e Cristal, muito suscetíveis) e em quatro grupos para resistência ao PVY (Asterix, Astrid, Catucha, Cristal, Macaca, Monte Bonito, A-1139-12-92, C-1226-35-80 e C-1714-7-94, resistentes; Baronesa, Santo Amor, Monalisa, Panda e 2CRI-1149-1-78, resistentes intermediários; Bintje, Atlantic, Elvira e Araucária, suscetíveis; Achat e Eliza, muito suscetíveis).

Molecular markers within or close to genes of interest play essential roles in marker-assisted selection. PCR-based markers have been developed for numerous traits in different plant species including several genes conferring resistance to viruses in potato. In the present work, rapid and reliable approaches were developed for the simultaneous detection of Ryadg and Ry-fsto, Ns, and PLRV.1 genes conferring resistance to Potato virus Y, Potato virus S and Potato leafroll virus, respectively, on the basis of previously published and newly modified markers. The sequence characterized amplified region (SCAR) markers for Ryadg, Ns and PLRV1 and the newly modified cleaved amplified polymorphic sequences (CAPS) marker for Ry-fsto were amplified in one PCR reaction which could simply characterize Ryadg and PLRV.1 resistance. Additional digestion of amplicons with EcoRV and MfeI for genotyping the Ry-fsto and Ns resistance genes, respectively, was needed. The effectiveness of genotyping in triplex and tetraplex PCRs was tested on 35 potato varieties used for potato seed production and breeding programs.
