Assessing the genetic diversity of Panicum coloratum var. makarikariense using agro‐morphological traits and microsatellite‐based markers
Armando, Lorena; Tomas, Maria Andrea; Garayalde, Antonio Francisco; Carrera, Alicia Delia (2015-11)Panicum coloratum var. makarikariense is a perennial C4 grass native to South Africa with relatively good forage production under limited‐resource conditions. Genetic characterisation and breeding efforts have been scant, ... -
Caracterización de germoplasma de Panicum coloratum L. VAR. coloratum para la tolerancia a la salinidad, alcalinidad y al frío
Pittaro, Gabriela (Edición del Autor, 2017-11)Los resultados demostraron que la población colectada de P. coloratum fue más tolerante a la salinidad que el cultivar comercial `Klein´. La variabilidad interna de esta población, en el crecimiento de los materiales en ... -
Collection and morphological characterization of Panicum coloratum L. in Argentina
Armando, Lorena; Carrera, Alicia Delia; Tomas, Maria Andrea (2013-06)Panicum coloratum (Poaceae) is a perennial grass native to South Africa, distributed all over the world, but poorly adopted by ranchers in Argentina. Adapted to a wide range of soil and climatic conditions, it constitutes ... -
Combined effect of salinity and hypoxia in seedlings of two varieties of Panicum coloratum: morphology, root system architecture, oxidative damage and antioxidant response
Lifschitz, Mauro Ezequiel; Tommasino, Exequiel Arturo; Zabala, Juan Marcelo; Grunberg, Karina; Ramos, Julio Cesar; Tomas, Maria Andrea (Wiley, 2021-09)The effect of the combination of salinity and waterlogging may be additive, or alternatively, more or less detrimental than effects of them separately. Our objective was to evaluate the effects of waterlogging, salinity ... -
Effect of pollination mode on progeny of Panicum coloratum var. makarikariense: Implications for conservation and breeding = Efecto del modo de polinización sobre la progenie de Panicum coloratum var. makarikariense: Implicaciones para conservación y fitomejoramiento
Armando, Lorena; Tomas, Maria Andrea; Garayalde, Antonio Francisco; Carrera, Alicia Delia (CIAT, 2017-09)Panicum coloratum var. makarikariense, a perennial grass native to Africa, is adapted to a wide range of soil and climatic conditions with potential to be used as forage in tropical and semi-arid regions around the world. ... -
Interacción genotipo x ambiente en familias de medios hermanos de Melilotus albus / Genotype-environment interaction in half-sib families of melilotus albus
Arolfo, Valeria; Tomas, Maria Andrea; Lavandera, Javier Eduardo; Re, Alejo Esteban; Acuña, Mariela Luciana; Lifschitz, Mauro Ezequiel; Odorizzi, Ariel (AAPA, 2016)El objetivo fue evaluar la interacción genotipo x ambiente (GxE) en familias de medios hermanos de una población de Melilotus albus y determinar la mejor estrategia de selección para la mejora genética de la población -
Panicum coloratum seed yield components in a farmer's field under diverse fertilization
Mattera, Juan; Tomas, Maria Andrea; Lifschitz, Mauro Ezequiel; Giordano, Mabel Cristina; Pacente, Ezequiel Martin (2019-05)Kleingrass (Panicum coloratum var. coloratum) is widely adapted to Argentinian Central La Pampa region, with desirable traits including persistence and high nutrition value. Despite this, Kleingrass utilization by growers ... -
Perception of factors affecting tropical forage grass seed production in Argentina
Tomas, Maria Andrea; Mattera, Juan (2019-05)In Argentina there is an extended region where tropical pastures have shown adaptation to diverse stresses and climate change. Despite their potential role in livestock systems tropical pastures have been underutilized, ... -
Phenotypic plasticity to drought in seedlings of the warm season grass Panicum coloratum is related to collection site
Giordano, Mabel Cristina; Grimoldi, Agustin Alberto; Tomas, Maria Andrea (Wiley, 2019-09)Phenotypic plasticity is the ability of organisms to modify their phenotype in response to environmental changes. We estimated and compared the amount of phenotypic plasticity in response to drought in seedlings of different ... -
Plasticidad fenotípica en Panicum coloratum: variabilidad genética, heredabilidad y expresión diferencial de la plasticidad
Giordano, Mabel Cristina (Facultad de Agronomía, Universidad de Buenos Aires, 2018-06)Plasticidad fenotípica es la capacidad de un genotipo de generar diferentes fenotipos cuando es expuesto a diferentes ambientes. Desde el punto de vista genético, en plantas de uso agronómico como las forrajeras megatérmicas, ... -
Pre-breeding studies in Panicum coloratum var. coloratum: Characterization using agro-morphological traits and molecular markers = Estudios de pre-mejoramiento genético en Panicum coloratum var. coloratum : caracterización usando marcadores moleculares y caracteres agro-morfológicos
Burgos, Estanislao; Thompson, Carolina Soledad; Giordano, Mabel Cristina; Tomas, Maria Andrea (CIAT, 2018)Panicum coloratum var. coloratum is a native African perennial C4 grass, introduced to Argentina. It is tolerant of salinity and cold and has good forage production. The scarce genotypic and phenotypic information about ... -
Producción de forraje y componentes estructurales en líneas experimentales de Melilotus albus
