A inteligência digital, pelas mais variadas formas, chegou ao campo. O uso de tecnologias da informação e da comunicação (TIC) é realidade no meio rural brasileiro. Em maior ou menor grau, produtores rurais, assistentes técnicos e gestores de empresas do setor agrícola são usuários e demandam cada vez mais novos produtos e serviços que envolvem a integração digital. São partes desse segmento: canais online/plataformas para compra de insumos (sementes, fertilizantes agroquímicos, etc.), máquinas e equipamentos e de comercialização da produção; sistemas de planejamento e gestão financeira e de riscos dos empreendimentos rurais; e uso de ferramentas de Agricultura de Precisão. |

Stay-green maize genotypes have been associated with tolerance to biotic and abiotic stresses, including tolerance to drought, and to stalk and root lodging, but there is limited information on its inheritance. Thus, this research was conducted to study the inheritance of the stay-green trait using both conventional analysis and QTL mapping of the Design III in a tropical maize population developed from two inbred lines genetically divergent for this trait. Two-hundred and fifty F2 plants were genotyped with 177 microsatellite markers, and their backcrossed proge-nies to both parental inbreds were evaluated at three locations. Ten plants per plot were assessed 120 days after sowing and the plot means scores for stay-green, adjusted for days to silking emergence, were used for analysis. The additive variance was larger than the dominance variance, the genetic by location interaction variance presented a high magnitude, and the heritability coefficient on a plant-basis a low magnitude. Seventeen QTL were mapped, most of them were clustered on four chromosomes and accounted for by 73.08 % of the genetic variance. About half of the QTL interacted with location, and the average level of dominance was partial dominance. The additive effects were larger than the dominance effects; the latter were not unidirectional, so that heterosis could not be exploited in crosses. Procedures for marker-assisted selection to increase the level o fstay-green are discussed and an approach is suggested for using both stable and non-stable QTL in a marker-assisted backcross program.
