Abstract Fusarium head blight (FHB) is a disease of wheat (Triticum aestivum L.) that causes major yield losses in South America, as well as many other wheat growing regions around the world. FHB results in low quality, contaminated grain due to the production of mycotoxins such as deoxynivalenol (DON). In Brazil, FHB outbreaks are increasing in frequency and are currently controlled by fungicides which are costly and potentially harmful to the wider environment. To identify the genetic basis of resistance to FHB in Brazilian wheat, two mapping populations (Anahuac 75 × BR 18-Terena and BR 18-Terena × BRS 179) segregating for FHB resistance were phenotyped and quantitative trait loci (QTL) analysis was undertaken to identify genomic regions associated with FHB-related traits. A total of 14 QTL associated with FHB visual symptoms were identified, each of which explained 3.7?17.3% of the phenotypic variance. Two of these QTL were stable across environments. This suggests FHB resistance in Anahuac 75, BR 18-Terena and BRS 179 is controlled by multiple genetic loci that confer relatively minor differences in resistance. A major, novel QTL associated with DON accumulation was also identified on chromosome 4B (17.8% of the phenotypic variance), as well as a major QTL associated with thousand-grain weight on chromosome 6B (16.8% phenotypic variance). These QTL could be useful breeding targets, when pyramided with major sources of resistance such as Fhb1, to improve grain quality and reduce the reliance on fungicides in Brazil and other countries affected by FHB.

Por décadas, na hinterlândia amazônica, o uso de candeeiros, lampião e lamparinas com uso de combustól, iluminavam as habitações e caminhos na densa floresta ao som da fauna noturna. As comunicações percorriam longas distancias no motor da linha, barco do recreio, ou navegavam lentamente a força do remo e dos banzeiros dos rios. A partir da década de 2010, fez-se a luz na densa floresta, a hinterlândia iluminou-se, desde então, não se vislumbra a dança dos lampyridios, a televisão e o celular ocuparam o espaço-tempo das famílias. Na década de 2020, com a sindemia covídica, a conversa eletrônica entrou em ação, com mensagens mais rápidas, anuncia notícias tristes e alegres, convoca ações de trabalho em regime de ajuri (sistema de trabalho coletivo, social e solidário), as novidades da família nuclear e extensa, a oferta de produtos, preços e prazos de entregas. Nesse sentido, objetivou-se identificar as Tecnologias da Informação e Comunicação (TICs), utilizadas no espaço agrário do Distrito Agropecuário da Suframa (DAS), comunidade Unidos Venceremos - DAS/ZF4, zona rural da cidade de Manaus-AM, como garantia de trabalho e renda, bem como, a oferta de produtos da agricultura familiar aos consumidores urbanos. |
