Association mapping to identify molecular markers associated with resistance genes to stink bugs in soybean
(Springer, 2021-02)Damage generated by insects is one of main restricting factors for soybean production. Stink bugs are a great threat within pests because, by feeding mainly on pods, they cause direct and irreversible damage to developing ... -
Caracterización genética de germoplasma de maní cultivado [Arachis hypogaea L.] mediante el empleo de marcadores microsatélitales = Genetic characterization of cultivated peanut genetic resources (Arachis hypogaea L.) using microsatellite markers
(2014)El maní cultivado (Arachis hypogaea L.), es una especie de gran importancia económica, nativo de América del Sur. Se divide en dos subespecies y seis variedades botánicas. Genéticamente es alotetraploide, constituido por ... -
Detecção de genes de resistência a Septoria tritici Rob. em trigo [Triticum aestivum (L.)]
(Escola Superior de Agricultura Luiz de Queiroz, Universidade de Sao Pablo, 2002-06)A mancha foliar provocada por Septoria tritici Rob. é uma das principais doenças do trigo em mais de 50 países, sendo responsável por significativas reduções na produtividade desta cultura. Os objetivos do presente trabalho ... -
Diversidad genética en genotipos de alfalfa (Medicago sativa L.) mediante marcadores SSR y características agronómicas
(2018-11-11)La alfalfa es una leguminosa, perenne y autotetraploide (2n=4x=32). Los cultivares son poblaciones sintéticas obtenidas por tres o cuatro generaciones de panmixia a partir de un conjunto de varios parentales (Flajoulot et ... -
Fenotipado y genotipado con marcadores SSR de líneas endocriadas de girasol (Helianthus annuus L.), contrastantes para la tolerancia al estrés hìdrico
(2019-03-21)El girasol (Helianthus annuus var. macrocarpus) es el segundo cultivo oleaginoso más importante en la Argentina. Desde hace varios años, se vienen realizando diferentes estudios agronómicos, fisiológicos y genéticos con ... -
Genetic characterization of sunflower breeding resources from Argentina: assessing diversity in key open-pollinated and composite populations
(Cambridge University Press, 2013-03-25)Open-pollinated (OPs) and composite populations (CPs) represent a valuable resource for sunflower breeding programmes. However, little is known about the levels and distribution of genetic variation within each of these ... -
Genetic diversity among alfalfa genotypes [Medicago sativa L.] of nom-dormant cultivars using SSR markers and agronomic traits = Análisis de la diversidad genética en genotipos de alfalfa (Medicago sativa L.) sin dormición, mediante el uso de marcadores SSR y caracteres agronómicos
(2013)The aim of this study was to assess genetic diversity among 40 alfalfa (Medicago sativa L.) genotypes of different non-dormant (FD=8) cultivars. Biomass yield, regrowth speed and reaction to spring black stem, lepto leaf ... -
Identification of leaf rust resistance genes in selected Argentinean bread wheat cultivars by gene postulation and molecular markers
(Pontificia Universidad Católica de Valparaíso, 2011)Leaf rust, caused by Puccinia triticina Eriks. is a common and widespread disease of bread wheat (Triticum aestivum L.), in Argentina. Host resistance is the most economical, effective and ecologically sustainable method ... -
Molecular and mycotoxin characterization of Fusarium graminearum isolates obtained from wheat at a single field in Argentina
(2016-01)Fusarium graminearum is the primary causal agent of Fusarium head blight of wheat in Argentina. This disease affects yield losses and quality of grains, reducing the wheat end-use, also causing mycotoxin contamination. In ... -
RYR1 gene variability and effect on meat pH in Argentinean hybrids swines = Variabilidad del gen RYR1 y efecto en el pH de la carne en cerdos híbridos argentinos
(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2012)The RYR1 gene is the principal cause of the porcine stress syndrome (PSS) and the presence of pale, soft and exudative meat (PSE) in swine. In Argentina there are no reports about the variability of RYR1 gene in hybrid ... -
Selection of Contrasting Parents for Drought Tolerance in Sunfower (Helianthus Annuus L.)
(Research Square, 2021-12-20)The aim of this research was select the best combination of contrasting parents to develop a mapping population for drought tolerance, based on phenotypic and genotypic data. Phenotyping was conducted in a greenhouse during ... -
SSR markers linked to stem canker resistance in soybean Glycine max
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020)In this work, we studied 40 samples of Diaporthe phaseolorum var. meridionalis (Dpm), causal agent of stem canker in soybeans (SCS). In the susceptible genotype Golondrina65 the isolate RSF12 showed the highest percentage ... -
Uso de germoplasma exótico para el mejoramiento de la resistencia genética a factores bióticos que afectan el cultivo de soja en Argentina
(2014)En Argentina la ganancia genética lograda en soja entre los años 1980 y 2000 fue de 14,3 Kg/ha/año, lo que representa el 62 % del incremento en rendimiento logrado en este período. Esto fue posible debido al uso de pocos ...
