Aporte a resistencia a enfermedades, calidad industrial y resistencia a herbicidas de distintos orígenes de germoplasma de girasol en tres períodos de mejoramiento
(Ediciones INTA, 2019-04)La Estación Experimental Agropecuaria Pergamino de INTA conduce un programa de mejoramiento de Girasol desde 1939. A través de los años el mejoramiento produjo modificaciones en el germoplasma para lograr adaptación a los ... -
Assessment of physiological races of Exserohilum turcicum isolates from maize in Argentina and Brazil
(Springer, 2021-02)Northern corn leaf blight (NCLB) is one of the most important diseases in maize worldwide. It is caused by the fungus Exserohilum turcicum, which exhibits a high genetic variability for virulence, and hence physiological ... -
Caracterización de nuevos aislados de Drechslera tritici-repentis y su efecto sobre el comportamiento de cultivares de trigo
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2015-04)Actualmente, se conocen en el mundo ocho razas de Drechslera tritici-repentis (Died) (teleomorfo Pyrenophora tritici-repentis, Died) determinadas sobre líneas diferenciales de trigo; sin embargo muchos investigadores ... -
Detecting sources of resistance to multiple diseases in Argentine maize (Zea mays L.) germplasm
(Springer Nature, 2022-04)Maize (Zea mays L.), an important cereal for human and animal nutrition, is usually affected by multiple co-occurring pathogens that reduce production. Argentina is the fourth maize producer worldwide, with common rust ... -
Evaluación de genotipos de maíz para la resistencia frente al estriado foliar bacteriano causado por xanthomonas vasicola pv. vasculorum
(2023-09)La estría foliar bacteriana causada por Xanthomonas vasicola pv. vasculorum (Xvv) que afecta al cultivo de maíz, causa grandes pérdidas económicas. El objetivo del trabajo fue evaluar un grupo de 60 líneas endocriadas de ... -
Genomics-assisted breeding for quantitative disease resistances in small-grain cereals and maize
(MDPI, 2020-12-19)Generating genomics-driven knowledge opens a way to accelerate the resistance breeding process by family or population mapping and genomic selection. Important prerequisites are large populations that are genomically ... -
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 ... -
Metaanálisis de transcriptomas de maíz (Zea Mays L.) en respuesta a fusarium verticillioides, f. graminearum y ustilago maydis
(Asociación de Ingenieros Agrónomos del Norte de la Provincia de Buenos Aires, 2022-11)Maize (Zea mays L.) ears are affected by several pathogens that impact grain yield and quality, such as Fusarium verticillioides (necrotroph), F. graminearum (hemibiotroph) and Ustilago maydis (biotroph). Even though there ... -
Molecular mapping of Asian soybean rust resistance in soybean landraces PI 594767A, PI 587905 and PI 416764
(Wiley, 2015-02)Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is one of the most serious diseases of soybean. The soybean landraces PI 594767A, PI 587905 and PI 416764 previously showed high levels of resistance to a wide ... -
Multi-parental QTL mapping of resistance to white spot of maize (Zea mays) in southern Brazil and relationship to QTLs of other foliar diseases
(Wiley, 2021-10)Maize white spot (MWS) is one of the most important foliar diseases in Brazil causing significant yield losses. Breeding genotypes with MWS resistance is the most sustainable alternative for managing such losses; however, ... -
No Common Candidate Genes for Resistance to Fusarium graminearum, F. proliferatum, F. sporotrichioides, and F. subglutanins in Soybean (Glycine max L.) Accessions from Maturity Groups 0 and I: Findings from Genome-Wide Association Mapping
(The American Phytopathological Society, 2024-04)Seedling diseases and root rot, caused by species of Fusarium, can limit soybean (Glycine max L.) production in the United States. Currently, there are few commercially available cultivars resistant to Fusarium. This study ... -
Las poblaciones locales de maíz como fuente para la resistencia a enfermedades
(Ediciones INTA, 2018-12)Las poblaciones locales de maíz pueden aportar atributos génicos originales para la resistencia a enfermedades. Obtener esa información conlleva un proceso arduo y sistemático de evaluación de los materiales. En el presente ... -
Respuesta hormonal del maíz (Zea mays L.) durante la interacción con el patógeno Xanthomonas vasicola pv. vasculorum
(2023-09)La interacción entre el maíz (Zea mays L.) y Xanthomonas vasicola pv. vasculorum (Xvv), causante del rayado foliar bacteriano emergente en Argentina, ha sido poco explorada. Las hormonas juegan un rol crucial en la defensa ... -
Transcriptional and metabolic changes associated to the infection by Fusarium verticillioides in maize inbreds with contrasting ear rot resistance
