Abstract:
Septoria tritici blotch (STB) is a major foliar disease globally, which is notorious in the fast development of fungicide resistance, making host resistance an indispensable component in mitigating STB. CIMMYT wheat line Murga is well known for its high, durable, and broad-spectrum resistance against STB infection, and the purpose of this study was to investigate its resistance mechanism to facilitate its utilization in breeding. A recombinant inbred line population was derived from a cross between Murga and a STB susceptible line Huirivis#1, comprising 297 progenies. The population was evaluated for adult-plant STB resistance in Toluca, Mexico (from 2017 to 2019), and in La Estanzuela, Uruguay (from 2016 to 2018). Genotyping was performed with the DArTSeq platform. QTL mapping indicated a major and stable QTL on chromosome 3DL, explaining a phenotypic variation for STB of 41.2-62.5% in Mexico and 27.5-40.3% in Uruguay. This QTL was regarded as Stb16 based on comparison of its physical position, the possible origin from synthetic wheat, and its broad-spectrum resistance. Additional QTL with minor effects were identified on chromosomes 2B, 2D, 3A, 3B, and 5B. The one on 5BS was significant in four out of the six environments and must be new. Murga was the resistant donor for all QTL, except for those on 2B and 3A. Being an elite breeding line, the Stb16 carrier Murga could be used as a promising STB resistance donor. The rational employment of Stb16 could contribute to STB management yet avoid the rapid emergence of Stb16-virulent isolates. MenosAbstract:

Los productores familiares y sobre todo los dedicados a la horticultura, se han enfrentado en las últimas dos décadas a bajas importantes en los precios reales de los productos que venden, y a un aumento de los precios de los insumos y de la energía que necesitan para producir. Una forma de atenuar el impacto en los ingresos, de estos cambios en los mercados, ha sido producir más. |
