Ecophysiological traits in maize hybrids and their parental inbred lines: Phenotyping of responses to contrasting nitrogen supply levels
(Elsevier, 2009-10)Maize (Zea mays L.) breeding based primarily on final grain yield has been successful in improving this trait since the introduction of hybrids. Contrarily, understanding of the variation in ecophysiological processes ... -
Efecto del secado y manejo agronómico sobre propiedades físicas asociadas a la dureza del grano en híbridos de maíz
(Universidad Tecnológica Nacional, Argentina, 2022-06-22)Se evaluó el efecto de distintos tratamientos de secado (natural, 50 y 70 °C) y manejo agronómico (sin y con re-fertilización en pre-floración) sobre la dureza endospérmica en cuatro híbridos de maíz (AW 190, NK 940, Cóndor ... -
Evaluación del rendimiento y otros atributos agronómicos en el germoplasma comercial de girasol argentino (1986-2006)
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-12)El mejoramiento genético de girasol en la Argentina resultó en un progreso genético constante para rendimiento en todas las regiones de cultivo de esta especie. En este trabajo, se aplicaron análisis de modelos lineales ... -
Kernel weight responses to the photo-thermal environment in maize dent × flint and flint × flint hybrids
(American Society of Agronomy, 2021-02)Maize (Zea mays, L.) grain yield is assumed to be source limited during the flowering period but sink limited during grain growth; however, environmental restrictions during active grain filling may strongly affect final ... -
Phenotypic plasticity for biomass partitioning in maize : genotype effects across a range of environments
(Elsevier, 2020-10)El rendimiento en grano de maíz está determinado por el genotipo (G), el ambiente (E) y los efectos de la interacción G × E que influyen en la expresión de los rasgos a lo largo del ciclo del cultivo. Líneas endocriadas e ... -
Responses to N Deficiency in Stay Green and Non-Stay Green Argentinean Hybrids of Maize
(2016-06)Breeding has developed better yielding maize hybrids for low N environments, which also have delayed leaf senescence (‘stay green’ trait, SG). Here, we studied whether the SG trait can further improve yield of modern hybrids ... -
Severity of Fusarium ear rot and concentration of fumonisin in grain of Argentinian maize hybrids
(Elsevier, 2007-06)Fusarium ear rot severity and fumonisin concentration in grain of 16 Argentinian maize hybrids were assessed after inoculation with Fusarium verticillioides. Differences among hybrids for both traits indicate that field ... -
Source-sink relations and kernel weight in maize inbred lines and hybrids : responses to contrasting nitrogen supply levels
(Elsevier, 2019-01)Maize (Zea mays, L.) kernel weight (KW) is regulated by the source-sink relationship at the early grain-filling period, when potential kernel size is defined, and at the effective grain-filling period, when final KW is ... -
Water and radiation use efficiencies in maize: breeding effects on single-cross Argentine hybrids released between 1980 and 2012
(Elsevier, 2019-11)Water deficit has been signaled as an important determinant of grain yield (GY) gaps between potential and actual GYs. Breeding for improved water as well as solar radiation productivities is a sustainable means to reduce ...
