Map overlapping of QTL for resistance to Fusarium ear rot and associated traits in maize
(Springer, 2021-04)Mapping QTL for disease resistance and associated traits is important to develop maize (Zea mays L.) hybrids less susceptible to ear rots. A biparental mapping population of 298 F5 recombinant inbreds (RIs), obtained from ... -
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 ... -
Yield determinants, root distribution and soil water uptake in maize (Zea mays) hybrids differing in canopy senescence under post-silking drought
(CSIRO Publishing, 2021-05)Delayed canopy senescence or ‘stay-green’ (SG) trait in maize (Zea mays L.) could improve drought tolerance. Two field trials comparing four to six maize hybrids with different senescence rate were carried out at Buenos ... -
Assessment of phenotypic variability among EEA INTA Pergamino sunflower lines: Its relationship with the grain yield and oil content
(2021-05)The aims of the present study were to assess the phenotypic diversity among 221 sunflower accessions of INTA Pergamino Sunflower Breeding Program, to obtain discriminant functions that allow the classification of new ... -
Prospects for plant productivity: from the canopy to the nucleus
(Oxford University Press, 2021-05)Population growth has been closely associated with agricultural production, since the first famine predicted by Malthus (1798) up to the Green Revolution of the past century. Today, we continue to face increasing demand ... -
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 ... -
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 ... -
Evaluación del tizón foliar y la mancha púrpura en semilla de soja en Argentina = Evaluation of leaf blight and purple seed stain in soybean in Argentina
(Universidad de Costa Rica, 2021-05)El tizón foliar por Cercospora y la mancha púrpura de la semilla son enfermedades endémicas de la soja en Argentina. Objetivo. Evaluar la prevalencia, la incidencia y la severidad del tizón foliar por Cercospora y de la ... -
A practical guide to estimating the light extinction coefficient with nonlinear models—a case study on maize
(Springer Nature, 2021-06-12)The fraction of intercepted photosynthetically active radiation (fPARi) is typically described with a non-linear function of leaf area index (LAI) and k, the light extinction coefficient. The parameter k is used to make ... -
Junglerice (Echinochloa colonaL.) seedling emergence model as a tool to optimize pre-emergent herbicide application
(Italian Society for Agronomy, 2021-07)Junglerice (Echinochloa colona), one of the worst and most problematic weeds globally, causes significant economic losses due to yield loss and control cost increase. Taking into account that this weed emerges in approximately ... -
Wheat yield progress and stability during the last five decades in Argentina
(Elsevier, 2021-07)Improvement of grain yield (GY) at farm level, which is closely related to GY potential, seems to be the main alternative to increase wheat (Triticum aestivum L) production. The aim of current research was to assess the ... -
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 ... -
Relative performance of cluster algorithms and validation indices in maize genome-wide structure patterns
(Springer Nature, 2021-09)A number of clustering algorithms are available to depict population genetic structure (PGS) with genomic data; however, there is no consensus on which methods are the best performing ones. We conducted a simulation study ... -
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, ... -
Capacity and Intensity Indicators to evaluate the effect of different crop sequences and cover crops on soil physical quality of two different textured soils from Pampas Region
(Elsevier, 2021-11)Soil physical degradation is a current problem in Molisols of the Pampas Region under no-tillage (NT), that has been related to over-simplified agricultural systems with scarce or no rotations and long winter bare fallows. ... -
