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 ... -
Germinación y residuos de plaguicida en semillas de coriandro (Coriandrum sativum L.) cultivadas con aplicación de glifosato y paraquat en precosecha = Germination and residue of pesticide in coriander seeds (Coriandrum sativum L.) cultivated with pre-harvest application of glyphosate and paraquat
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2017)Es conocida la aplicación de desecantes, para acelerar y uniformizar el secado del cultivo de coriandro y de las malezas, que facilitan la cosecha de semillas. Para conocer sus efectos sobre el poder germinativo y ... -
Germination and infection of Phakopsora pachyrhizi under simulated environment of the central area of Santa Fe, Argentina
(2016)Soybean asian rust (SAR) caused by the fungus Phakopsora pachyrhizi was confirmed in Argentina for the first time during the 2002-2003 growing season. Then, the disease spread to the Northern and Eastern provinces, reaching ... -
Glyphosate resistance in perennial ryegrass (Lolium perenne L.) is associated with a fitness penalty
(2016)The net selection effect of herbicides on herbicide-resistance traits in weeds is conditioned by the fitness benefits and costs associated with resistance alleles. Fitness costs play an important evolutionary role preventing ... -
Grain hordein content and malt quality as affected by foliar nitrogen fertilisation at heading
(Wiley, 2021-05)Nitrogen fertilisation at heading is a practice for increasing grain protein content in malting barley. The objective of this study was to assess the effects of fertilisation on grain protein, the content and composition ... -
Heredabilidad, correlaciones genéticas, análisis de sendero e índices de selección en una población de girasol (Helianthus annuus) de la EEA INTA Pergamino
(Ediciones INTA, 2021-08)El primer paso en un programa de desarrollo de cultivares es formar una población con variabilidad genética para los caracteres de interés. La selección de progenies provenientes de poblaciones constituye una valiosa ... -
Heterogeneity in agricultural land use decisions in Argentine Rolling Pampas : the effects on environmental and economic indicators
(Taylor & Francis Group, 2019-09)Argentine Pampas are one of the major regions in the world for agricultural production. There is a trend towards system simplification in this area, with soybeans being the predominant crop. One major concern of “soybeanization” ... -
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 ... -
