Artificial selection for grain yield has increased net CO2 exchange of the ear leaf in maize crops
(Oxford University Press, 2021-03)Identifying the physiological traits indirectly selected during the search for high-yielding maize hybrids is useful for guiding further improvements. To investigate such traits, in this study we focused on the critical ... -
Assessing changes in enriched maize flour formulations after extrusionby means of FTIR, XRD, and chemometric analysis
(2018-10)Spectral analysis employing multivariate techniques was employed to differentiate plain maize flours from formulations containing maize with added milled chia or quinoa seeds for producing cereal breakfast extrudates. The ... -
Combining pedigree and genomic information to improve prediction quality : an example in sorghum
(Springer, 2019-07)Selection based on genome-wide markers has become an active breeding strategy in crops. Genomic prediction models can make use of pedigree information to account for the residual polygenic effects not captured by markers. ... -
Crop management affects dry-milling quality of flint maize kernels
(Elsevier, 2011-05)Dry-milling performance of maize (Zea mays, L.) kernels primarily depends on their hardness. The flint type is harder than the dent and semi-dent maize, yielding a higher proportion of big endosperm pieces in the mill. ... -
Edad de sacrificio y caracteres productivos a la faena en machos de un cruzamiento experimental de tres vías de pollo campero
(Facultad de Agronomía y Veterinaria, Universidad Nacional de Río Cuarto, 2018-05)El pollo campero es un tipo de ave de crecimiento lento, con un buen desarrollo de la pechuga, cuyo protocolo de certificación establece que debe ser faenado entre los 75 y los 90 días de edad. El objetivo de este trabajo ... -
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 ... -
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 ... -
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 ... -
Field-grown transgenic wheat expressing the sunflower gene HaHB4 significantly outyields the wild type
(2019-02)HaHB4 is a sunflower transcription factor belonging to the homeodomain-leucine zipper I family whose ectopic expression in Arabidopsis triggers drought tolerance. The use of PCR to clone the HaHB4 coding sequence for wheat ... -
Fruiting efficiency : an alternative trait to further rise wheat yield
(2015-07)Further improvements in wheat yields are critical, for which increases in grain number would be required. In the recent past, higher grain number was achieved through increased growth of the juvenile spikes before anthesis, ... -
Gaps between farmer and attainable yields across rainfed sunflower growing regions of Argentina
(Elsevier, 2013-03-01)We computed three estimators of attainable yield for each of between 5 and 8 rainfed sunflower-growing regions of Argentina using between 5 and 9 years of data over the 2000–2007 interval. The estimators were based on ... -
Genomic prediction of grain yield and drought-adaptation capacity in sorghum is enhanced by multi-trait analysis
(Swedish University of Agricultural Sciences, 2019-07)Grain yield and stay-green drought adaptation trait are important targets of selection in grain sorghum breeding for broad adaptation to a range of environments. Genomic prediction for these traits may be enhanced by joint ... -
Kernel number and kernel weight determination in dent and popcorn maize
(Elsevier, 2011-02)Yield formation in maize (Zea mays L.) dent hybrids has been directly linked to the rate of plant biomass accumulation and partitioning of assimilates to the developing grain. Maize popcorn genotypes have been studied less ... -
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 ... -
Líneas de girasol de la EEA Pergamino
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)Se analizaron tres grupos de líneas de girasol (Helianthus annuus) de la EEA Pergamino del INTA. Grupo 1: líneas derivadas de los compuestos P1, P2, P4, PGRK y KLM liberadas en la década del 90. Grupo 2: líneas GP logradas ... -
Maize genetic progress in the central Pampas of Argentina: effects of contrasting sowing dates
(Elsevier, 2022-05)Delayed sowing date of maize (Zea mays L.) has become a broadly adopted practice in the Pampas region of Argentina, because late-sown crops frequently experience a more favorable water balance around flowering and a reduction ... -
Mejores prácticas de manejo de la fertilización de trigo : dos experiencias de INTA 9 de Julio
(2013-03)Las mejores prácticas de manejo (MPM) de uso de fertilizantes involucran aplicar la fuente de nutriente correcta, en la dosis, el momento y el lugar correctos. Estas decisiones son críticas para alcanzar una óptima eficiencia ... -
Multi-parent QTL mapping reveals stable QTL conferring resistance to Gibberella ear rot in maize
(Springer, 2020-12)Maize production is on risk by Gibberella ear rot (GER) caused by Fusarium graminearum. This is one of the most important ear rot diseases in temperate zones as it leads to yield losses and production of harmful mycotoxins. ...
