Conteúdo: | This study selected cowpea offspring with (i) white rugose coat seed characteristics that are accepted by markets and (ii) that present resistance to CPSMV (serotype I) and CABMV. The first selection of asymptomatic plants was carried out using seedlings from F3 seeds mechanically inoculated with a mixture of the two viruses. Offspring F3:4 went through a second selection process with two stages, one in the field (with natural inoculation), one in trays (with mechanical inoculation). In total, 40 F3:4 offspring were selected to evaluate agronomic traits in two field assays, one in Teresina, one in Tracuateua (states of Piauí and Pará, respectively) based on a randomized block design with four repetitions.
