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 ... -
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 ... -
Fin de las reservas de fertilizantes fosfatados: ¿realidad o restricciones geopolíticas?
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2022-08-30)El fósforo (P) es un elemento fundamental para toda la vida en la tierra, y no presenta un sustituto en la producción de alimentos. El suministro de P desde las reservas de rocas fosfóricas está concentrado en unos pocos ... -
First report of spot lesion of wheat caused by Pyrenophora teres f. sp maculata observed in Argentina
(2019-08)Pyrenophora tritici-repentis, causal agent of tan spot, is the species commonly associated with leaf spotting symptoms on wheat (Triticum aestivum L.) worldwide and in Argentina. On the other hand, P. teres is a major ... -
Fracciones de fósforo edáfico bajo diferentes manejos = Phosphorus fractions under different managements
(Asociación Argentina de la Ciencia del Suelo, 2022-12)El fósforo (P) es uno de los nutrientes que más limita la producción agrícola. A nivel mundial, la región pampeana presenta los mayores déficits de P edáfico. Como su existencia en el suelo varía desde iones en solución a ... -
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, ... -
FT-IR and untargeted chemometric analysis for adulterant detection in chia and sesame oils
(Elsevier, 2019-05)Chia (Salvia hispanica L.) and sesame (Sesamum indicum L.) oils are valorized for their health benefits and both are extensively used as ingredients in different food formulations and/or processes. Their retail prices are ... -
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 ... -
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 relatedness and population structure within the public Argentinean collection of maize inbred lines
(2014)Genetic diversity of an Argentinean public temperate inbred maize collection has not been previously assessed. This collection includes mainly locally developed orange flint germplasm and a group of temperate inbred lines ... -
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 ... -
Genomic prediction for broad and specific adaptation in sorghum accommodating differential variances of SNP effects
(American Society of Agronomy, 2020-05)This paper reports a first study exploring genomic prediction for adaptation of sorghum [Sorghum bicolor (L.) Moench] to drought‐stress (D‐ET) and non‐stress (W‐ET) environment types. The objective was to evaluate the ... -
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 ... -
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 ... -
