A genome-wide association study unveils key chromosome regions involved in determining sodium accumulation in wheat under conditions of low potassium supply
(Elsevier, 2022-05-30)Improving nutrient use efficiency is an important objective in modern breeding programs. In this work, we examined potassium utilization efficiency (KUtE) and traits potentially related to it in a formerly genotyped, ... -
Allelic variation of puroindolines genes in Iranian common wheat landraces
(MDPI, 2022-08-10)Wheat is one of the most widely grown crops in the world. One of the traits that defines wheat quality is grain hardness, which is determined by puroindolines (PINA and PINB) proteins encoded with Pina-D1 and Pinb-D1 genes. ... -

(EEA Oliveros, 2017)El objetivo de este trabajo fue analizar la evolución de la FET en la campaña 2016/17, en la EEA INTA Oliveros. Para ello, se utilizó una plataforma web de libre acceso y de uso sencillo, que permitió contrastar los valores ... -
Assessing Payne score accuracy through a bread wheat multi-genotype and multi-environment set from CIMMYT
(Elsevier, 2024-01-01)The Payne score is a prevalent strategy for assessing wheat quality by considering the distinct contributions of specific high-molecular-weight glutenin subunits. Despite its extensive use, the limited germplasm used in ... -
Calidad de la materia orgánica y disponibilidad de macro y micronutrientes por la inclusión de trigo como cultivo de cobertura
(2016-06)Los cultivos de cobertura aparecen como una opción que permite mejorar el balance de nutrientes y carbono en el suelo (C). El objetivo del presente trabajo fue determinar el efecto de la incorporación del trigo como cultivo ... -
Characterization of the repetitive DNA landscape in wheat homeologous group 4 chromosomes
(2015)Background: The number and complexity of repetitive elements varies between species, being in general most represented in those with larger genomes. Combining the flow-sorted chromosome arms approach to genome analysis ... -
Como planificar la siembra de trigo ante un escenario hídrico heterogéneo
(INTA, 2022-05-11)En un contexto general de déficit hídrico y la posibilidad de un invierno seco, especialistas del INTA detallan cómo se encuentran las zonas trigueras, de acuerdo a las últimas lluvias. Entre las recomendaciones ponen el ... -
Criterios de selección fenotípica en el mejoramiento vegetal: mirando debajo de la alfombra
(INTA, 2022-11-03)¿En qué punto nos encontramos? Creciente demanda mundial de alimentos. Necesidad de aumentar la productividad de los cultivos en forma sustentable. Contraste con los objetivos de la revolución verde del siglo XX: aumento ... -
Desarrollo y uso de sistemas de pronóstico de epidemias de la Fusariosis de la espiga de trigo (Triticum aestivum L.) para identificar situaciones sinópticas y predictores meteorológicos en diferentes escalas asociados a la enfermedad en la región pampeana
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2011-09)La fusariosis de la espiga de trigo (FET) causada por el hongo Fusarium graminearum constituye una amenaza multifacética al afectar tanto al rendimiento y calidad del trigo como a la salud humana por acción de micotoxinas. ... -
Down-regulation of catalase activity contributes to senescence induction in wheat leaves exposed to shading stress
(Springer, 2015-01)In shaded wheat (Triticum aestivum L.) leaves, the suppression of blue radiation (BR) triggers senescence. This phenomenon is correlated to an increase in oxidative stress symptoms and a decrease of catalase (CAT) activity, ... -
Efecto a corto plazo de la inclusión de vicia y trigo como cultivos de cobertura sobre el C, N y P en distintas fracciones de la materia orgánica, y la disponibilidad de macro y micronutrientes
(2018-08)La mayor participación de la soja entre los cultivos de verano sumada a los largos períodos de barbecho otoño-invernales han dado como resultado una importante reducción en el aporte de residuos y consecuentemente del ... -
Effect of the Hope FT-B1 Allele on wheat heading time and yield components
(2014-09)Precise regulation of flowering time is critical for plant reproductive success and, in cereals, to maximize grain yields. Seasonal cues including temperature and day length are integrated to regulate the timing of flowering. ... -
Effects of fertilizer type on nitrous oxide emission and ammonia volatilization in wheat and maize crops
(Wiley, 2022-01-28)About half of the applied nitrogen (N) is not consumed by crops, causing environmental and economic costs. This N can be lost as ammonia (NH3) volatilization, nitrous oxide (N2O) emission or leaching, among others. This ... -
Genetic and physical mapping of the earliness perse locus Eps - Am1 in Triticum monococcum identifies early flowering 3 (ELF3) as a candidate gene
(2016-07)Wheat cultivars exposed to optimal photoperiod and vernalization treatments still exhibit differences in heading time. This variation, known as earliness per se (Eps), is important for the fine-tuning of flowering and the ... -
Grain mineral composition of Argentinean-adapted wheat cultivars: a case study
(CSIRO, 2021-02-23)Abstract. Improvement of the nutritional quality of wheat (Triticum aestivum L.) has been quite challenging, due, in part, to the limited variation found in modern cultivars and the strong effect exerted by the environment, ... -
Has climate change opened new opportunities for wheat cropping in Argentina?
(Springer, 2013-03)As a result of climate change, and in particular rainfall changes, agricultural production is likely to change across the globe. Until now most research has focused on areas which will become unsustainable for agricultural ... -
