. Panel of sugarcane genotypes tested
Mosaic disease resistance was evaluated in 79 genotypes collected from different Brazilian Sugarcane breeding programs: 5 varieties from Centro de Tecnologia Canavieira (CTC and SP), 5 from Rede Interuniversitária para o Desenvolvimento do Setor Sucroenergético (RB varieties), 17 from Instituto Agronomico (IAC varieties), along with 50 IAC elite clones (Table 2). Stalks were collected from sugarcane stools without mosaic symptoms that had been maintained at the IAC Sugarcane Breeding Station, Ribeirão Preto, São Paulo, Brazil. Leaf samples of each stool were tested by PTA-ELISA (Plate Trapped Antibody-ELISA) to verify viable viral infection.
