Artificial selection for grain yield has increased net CO2 exchange of the ear leaf in maize crops
(Oxford University Press, 2021-03)Identifying the physiological traits indirectly selected during the search for high-yielding maize hybrids is useful for guiding further improvements. To investigate such traits, in this study we focused on the critical ... -
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 ... -
Evaluación del rendimiento y otros atributos agronómicos en el germoplasma comercial de girasol argentino (1986-2006)
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-12)El mejoramiento genético de girasol en la Argentina resultó en un progreso genético constante para rendimiento en todas las regiones de cultivo de esta especie. En este trabajo, se aplicaron análisis de modelos lineales ... -
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 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 ... -
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 ... -
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 ... -
Líneas de girasol de la EEA Pergamino
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)Se analizaron tres grupos de líneas de girasol (Helianthus annuus) de la EEA Pergamino del INTA. Grupo 1: líneas derivadas de los compuestos P1, P2, P4, PGRK y KLM liberadas en la década del 90. Grupo 2: líneas GP logradas ... -
Maize genetic progress in the central Pampas of Argentina: effects of contrasting sowing dates
(Elsevier, 2022-05)Delayed sowing date of maize (Zea mays L.) has become a broadly adopted practice in the Pampas region of Argentina, because late-sown crops frequently experience a more favorable water balance around flowering and a reduction ... -
El mejoramiento genético de cebadilla criolla (Bromus catharticus Vahl) en Argentina : síntesis de los logros y avances = The genetic improvement of prairie grass (Bromus catharticus Vahl) in Argentina : synthesis of achievements and advances
(Sociedad Argentina de Genética, 2023-07)La cebadilla criolla (Bromus catharticus Vahl) es la gramínea forrajera nativa anual/bianual de clima templado de mayor importancia y difusión en la Argentina. Varios autores han estudiado la variabilidad fenotípica en ... -
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 ... -
On-farm soybean genetic progress and yield stability during the early 21st century: A case study of a commercial breeding program in Argentina and Brazil
(Elsevier, 2024-03)CONTEXT: Most studies assessing the genetic progress in soybean have traditionally focused on retrospectives approaches, where commercial genotypes released over an extended period are tested in a limited number of ...
