Genetic inheritance analysis of the resistance to a virulent isolate of Colletotrichum acutatum in strawberry based on an octoploid model = Análisis de la herencia genética de la resistencia a un aislado virulento de Colletotrichum acutatum en frutilla basado en un modelo octoploide
(Facultad de Agronomía y Zootecnia, Universidad Nacional de Tucumán, 2017-12)In the present work we propose a hypothesis to explain the mechanism of the genetic control of resistance to anthracnose and we show an experimental model that may support our hypothesis. The inheritance of the strawberry ... -
Genetics and mapping of a new anthracnose resistance locus in Andean common bean Paloma

Híbridos de girasol con resistencia a Mildiu
(EEA Reconquista, 2018-06)El Mildiu del girasol (Plasmopara halstedii) es un patógeno que requiere un suelo húmedo y frío para prosperar, situaciones que no siempre se dan en la fecha de siembra óptima para nuestra región (entre el 15 de agosto ... -
Identification of leaf rust resistance genes in selected Argentinean bread wheat cultivars by gene postulation and molecular markers
(Pontificia Universidad Católica de Valparaíso, 2011)Leaf rust, caused by Puccinia triticina Eriks. is a common and widespread disease of bread wheat (Triticum aestivum L.), in Argentina. Host resistance is the most economical, effective and ecologically sustainable method ... -
In vivo and in vitro screening for resistance against Penicillium allii in garlic accessions
(Springer, 2019-11-14)Garlic blue mold disease, caused by Penicillium allii, is responsible for important economic losses produced yearly in garlic field crops and in postharvest storage. The identification of genetic resistance sources may ... -
Individual precocity, temporal persistence, and task-specialization of hygienic bees from selected colonies of apis mellifera
(2016)Hygienic behaviour is a complex trait that gives Apis mellifera L. resistance against brood diseases. Variability in the expression of hygienic behaviour is evidenced at the colonylevel and is explained by the proportion ... -
Influence of Fusarium spp. isolate and inoculum density on resistance screening tests in onion
(Brazilian Phytopathological Society, 2014)Fusarium basal rot (FBR), which is caused predominantly by Fusarium oxysporum and F. proliferatum, is the main limiting factor of onion crops. Resistant cultivars obtained in other countries do not behave as such in ... -
Integrating technologies for the sustainable control of gastrointestinal parasites in sheep : The Argentinean case
(FAO, 2023)Gastrointestinal nematode infections in sheep are a major concern among breeders due to the economic losses they cause in terms of a reduction in both productivity and viability of animals. The situation worsens in face ... -
Interacción diferencial entre cepas de Xanthomonas axonopodis y diversas rutaceas
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2007-12-18)Se caracterizaron cepas de los grupos B y C de Xanthomonas axonopodis (Xa) causantes de cancrosis tipo B y C en citrus. Se demostró diferencias en la patogenicidad y la falta de justificación para mantenerlas en un mismo ... -
Introgresión de fuentes de resistencia a roya común y tizón foliar en líneas endocriadas de maíz (Zea mays l.)
(Asociación de Ingenieros Agrónomos del Norte de la Provincia de Buenos Aires, 2022-11)Maize (Zea mays L.) is one of the most important crops worldwide and is affected by several pathogens that put productivity and grain quality at risk. Common rust (Puccinia sorghi) and northern corn leaf blight (Exserohilum ... -
Lipoxygenase activation in peanut seed cultivars resistant and susceptible to Aspergillus parasiticus colonization
(American Phytopathological Society, 2014-12)Accumulative evidence indicates that the lipoxygenase (LOX) pathway plays a significant role in the Aspergillus–seed interaction, such as interfering with activities of endogenous fungal oxylipins or producing antimicrobial ... -
