Ear reproductive development components associated with kernel set in maize: breeding effects under contrasting environments
(Elsevier, 2023-12)Context or problem: Kernel number per ear (KNE) is the main driver of improved grain yield per ear (GYE) in maize (Zea mays L.). Under non-limiting conditions, KNE responded to variations in ear developmental traits such ... -
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 ... -
Efectos de diferentes estrategias de fertilización sobre los rendimientos, el balance de nutrientes y su disponibilidad en los suelos en el largo plazo
(IPNI, 2015-09)A nivel productivo, las deficiencias de nitrógeno (N), fósforo (P) y azufre (S) no ocurren de manera aislada sino que se combinan de diversas maneras, por lo que es necesario evaluar integralmente la respuesta a la ... -
Enhancement of late-sown maize production with immobilized bacteria in chitosan/starch beads in different crop management conditions
(Springer Nature, 2024-01)Immobilization of plant growth-promoting rhizobacteria in biodegradable polymeric matrices has the potential to improve crop yield and overcome rhizosphere challenges. Previously, we demonstrated that beads prepared from ... -
Environment affects starch composition and kernel hardness in temperate maize
(Wiley, 2022-03)BACKGROUND: Protein percentage and kernel weight affect the endosperm hardness of maize grains. However, changes in starch composition could also modify kernel hardness, which is often predicted through milling ratio. The ... -
Environment, management, and genetic contributions to maize kernel hardness and grain yield
(2017-09)Dry milling performance of maize (Zea mays L.) is directly related to kernel hardness. This study assessed the contribution of maize hybrid and crop growing condition on kernel hardness and grain yield. Three hybrids that ... -
Expressing the sunflower transcription factor HaHB11 in maize improves waterlogging and defoliation tolerance
(Oxford University Press, 2022-05)The sunflower (Helianthus annuus) transcription factor HaHB11 (H. annuus Homeobox 11) belongs to the homeodomain-leucine zipper family and confers improved yield to maize (Zea mays) hybrids (HiII × B73) and lines. Here we ... -
Fertilización en sorgo en el norte y centro-oeste de Buenos Aires : rendimiento y eficiencia comparada al maíz
(2013-12)En este trabajo se presentan los resultados de un ensayo de respuesta del cultivo de sorgo a la aplicación de nitrógeno (N), fósforo (P), azufre (S), zinc (Zn) y boro (B) realizado en Pergamino (Buenos Aires) en la ... -
Fertilizer vs. organic matter contributions to nitrogen leaching in cropping systems of the Pampas: 15N application in field lysimeters
(Springer, 2006-11-07)Nitrogen (N) export from soils to streams and groundwater under the intensifying cropping schemes of the Pampas is modest compared to intensively cultivated basins of Europe and North America; however, a slowNenrichment ... -
Gene action controlling stability and adaptability in maize
(2016)Limited knowledge about the genetic merit of maize landraces contributes to their little use in breeding, al-though some reports pointed them as a source of useful alleles. Repeated cultivation of landraces ... -
Genetic diversity and linkage disequilibrium in the Argentine public maize inbred line collection
(2017)Knowledge of linkage disequilibrium (LD) patterns is considered a prerequisite for effective association mapping studies. However, no LD analysis in the Argentine public temperate maize collection has been reported to date. ... -
Genetic gains in grain yield and related physiological attributes in Argentine maize hybrids
(Elsevier, 2006-02)Genetic gains in grain yield and related phenotypic attributes have been extensively documented in maize (Zea mays L.), but the effect of breeding on the physiological determinants of grain yield is yet poorly understood. ... -
Genetic variability within accessions of the B73 maize inbred line
(2014)The maize inbred line B73 has been extensively studied at the molecular level. Researchers now have access to the genome sequence of B73 as well as to databases of biallelic and multiallelic markers where functional ... -
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 ... -
Higher than expected N2O emissions from soybean crops in the Pampas Region of Argentina: Estimates from DayCent simulations and field measurements
(Elsevier, 2022-08)In developing countries, agriculture generally represents a large fraction of GHG emissions reported in National Inventories, and emissions are typically estimated using Tier 1 IPCC guidelines. However, field data and ... -
