Metal cation concentrations improve understanding of controls on soil organic carbon across a precipitation by vegetation gradient in the Patagonian Andes
(Elsevier, 2023-12)Tephra-derived soils retain more organic carbon (C) than soils formed from any other parent material, but this C may be sensitive to changes in climate and land use. Here we evaluate the effects of precipitation, temperature, ... -
Methodological proposal for the characterization of accessions in Germplasm Banks using Generalized Procrustes Analysis applied to incomplete but connected trials
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2021-04)Characterization of plant material conserved in germplasm banks allows the study and analysis of the genetic variability within a collection. When germplasm banks have a large number of accessions, field evaluation should ... -
Mhc-B haplotypes in “Campero-Inta” chicken synthetic line
(Elsevier, 2019-11)The major histocompatibility complex-B (MHC-B) in chickens is a cluster of genes located on chromosome 16. The chicken MHC-B is known to be highly associated with resistance to numerous diseases caused by viruses, bacteria, ... -
MHC-B variation in maternal and paternal synthetic lines of the Argentinian Campero INTA chicken
(Elsevier, 2021-05)The Campero-INTA chicken of Argentina was developed to provide a robust bird that can survive under Argentinian pasture conditions with no significant additional nutrition, producing a source of animal protein for small ... -
Microstructural characteristics and physical properties of corn-based extrudates affected by the addition of millet, sorghum, quinoa and canary seed flour
(Elsevier, 2020-07)Corn flour blends including 25 % of pearl millet, red sorghum, quinoa or canary seed flours, not deeply studied in the extrusion process of corn-based products, were used for extrudates production. Several physical, ... -
Modeling economic-environmental decision making for agricultural land use in Argentinean Pampas
(2016-03)This research evaluates the economic and environmental impacts of land allocation to crops and extensive livestock production in the Argentine Pampas using compromise programming. Two economic indicators (gross margin, ... -
Modelling spatial trends in sorghum breeding field trials using a two-dimensional P-spline mixed model
(Springer, 2017-04)A flexible and user-friendly spatial method called SpATS performed comparably to more elaborate and trial-specific spatial models in a series of sorghum breeding trials. Adjustment for spatial trends in plant breeding field ... -
Molecular mapping of Asian soybean rust resistance in soybean landraces PI 594767A, PI 587905 and PI 416764
(Wiley, 2015-02)Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is one of the most serious diseases of soybean. The soybean landraces PI 594767A, PI 587905 and PI 416764 previously showed high levels of resistance to a wide ... -
Multi-Level approach for the analysis of water effects in corn flakes
(American Chemical Society, 2008-08)The purpose of this work was to analyze the effect of water on thermal transitions, mechanical properties, and molecular mobility in corn flakes (CF), and their relationships. Commercial common (CCF) and sugar-frosted (SCF) ... -
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. ... -
Multi-parental QTL mapping of resistance to white spot of maize (Zea mays) in southern Brazil and relationship to QTLs of other foliar diseases
(Wiley, 2021-10)Maize white spot (MWS) is one of the most important foliar diseases in Brazil causing significant yield losses. Breeding genotypes with MWS resistance is the most sustainable alternative for managing such losses; however, ... -
El nabo como recurso forrajero invernal en la producción de carne
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-08)El objetivo del trabajo fue evaluar la producción de carne con nabo forrajero (Brassica napus x B. oleracea cv Interval) en cultivo puro y en mezcla con avena bajo pastoreo con novillitos a fines del invierno. El experimento ... -
Nitrogen fertilization effects on forage production and nutritive value of 4 tropical grasses on alkaline soils in Argentina
(International Center for Tropical Agriculture (CIAT), 2023-09)This study evaluated effects of nitrogen (N) fertilization and gypsum application and their interactions on total pasture forage production and nutritive values of Chloris gayana cultivars ‘Santana’ and ‘Finecut’ and Panicum ... -
No Common Candidate Genes for Resistance to Fusarium graminearum, F. proliferatum, F. sporotrichioides, and F. subglutanins in Soybean (Glycine max L.) Accessions from Maturity Groups 0 and I: Findings from Genome-Wide Association Mapping
(The American Phytopathological Society, 2024-04)Seedling diseases and root rot, caused by species of Fusarium, can limit soybean (Glycine max L.) production in the United States. Currently, there are few commercially available cultivars resistant to Fusarium. This study ... -
Nutritional evaluation of dried tomato seeds
(Oxford Academic Press, 2003-01)Two samples of tomato seeds, a by-product of the tomato canning industry were evaluated to determine proximate analysis, amino acid content, and digestibility, TMEn, and protein efficiency ratio. Tomato seeds were also ... -
