Evaluación comparativa de distintas estrategias de análisis de datos para la caracterización y ordenamiento de la variabilidad genética de poblaciones locales de maíz (Zea mays L.)
(Universidad Nacional de Rosario, 2017-08)El maíz, siendo un cereal originario de América, presenta a lo largo de este continente una amplia variabilidad de tipos y formas. Sin embargo dicha variabilidad es muy poco utilizada por los fitomejoradores, por desconocimiento ... -

(Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2003-03)El objetivo de este trabajo fue estudiar la segregación de los caracteres de interés agronómico en la generación F2 de los híbridos provenientes de un cruzamiento dentro de L. esculentum var. esculentum, y un cruzamiento ... -
Evaluación de la variabilidad agromorfológica de poblaciones nativas de maíz de Misiones, Argentina
(Facultad de Ciencias Exactas, Químicas y Naturales, Universidad Nacional de Misiones, 2020-06)Las variedades locales de maíz presentan una gran relevancia socioeconómica en los sistemas agrícolas familiares de la provincia de Misiones. La pérdida de costumbres y tradiciones asociadas a su uso ponen en riesgo su ... -
Evidence of genetic diversity within Solanum Lycopersicum L. ‘Platense’ landrace and identification of various subpopulations
(Springer Nature, 2020-06-14)Local varieties and landraces are traditional crops that have evolved over time through adaptation to their natural and cultural environment. They are presently regarded as a valuable genetic reservoir, given that most of ... -
Exploiting genetic and physiological variation of the native forage grass Trichloris crinita for revegetation in arid and semi‐arid regions: An integrative review
(2018-06)In arid, semi‐arid and dry subhumid regions, which represent ~ 41% of the Earth's land surface, desertification and soil degradation are very frequent, leading to low soil fertility and productivity. In these regions, ... -
Fruit flesh volatile and carotenoid profile analysis within the Cucumis melo L. species reveals unexploited variability for future genetic breeding
(2018-08)Aroma profile and carotenoids content of melon flesh are two important aspects influencing the quality of this fruit that have been characterized using only selected genotypes. However, the extant variability of the whole ... -
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 and linkage disequilibrium in the Argentine public maize inbred line collection
(2017)Knowledge of linkage disequilibrium (LD) patterns is considered a prerequisite for effective association mapping studies. However, no LD analysis in the Argentine public temperate maize collection has been reported to date. ... -
Genetic diversity and patterns of population structure in Creole goats from the Americas
(Wiley, 2017)Biodiversity studies are more efficient when large numbers of breeds belonging to several countries are involved, as they allow for an in-depth analysis of the within- and between-breed components of genetic diversity. A ... -
Genetic diversity and population structure in Nothofagus pumilio, a foundation species of Patagonian forests: defining priority conservation areas and management
(Springer Nature, 2020-11)Patagonian forests are the southernmost temperate forests in the world, and Nothofagus pumilio is one of their most ecologically important tree species (i.e., a foundation species). It presents great adaptability and a ... -
Genetic diversity near the DGAT1-2 gene for high oleic acid content and kernel trait variation in a maize breeding collection
(2018-08)Previous studies in maize have identified three quantitative trait loci (QTLs) coding for high oleic acid content (HOAC) (QTLs oleic6-1, oleic6-2, and oleic6-3) at bins 6.04–6.05, proximal to the DGAT1-2 gene. The aims of ... -
Genetic diversity of GH1 and LEP genes in Argentine llama [Lama glama] populations
(2014)Compared to other domestic species, little is known about variability of genes related to energetic metabolism and growth in camelids. Here, we have analyzed leptin (LEP) and growth hormone (GH1) genes and characterized ... -
Genetic diversity of squash landraces (Cucurbita maxima) collected in Andean Valleys of Argentina = Diversidad genética de poblaciones de zapallo (Cucurbita maxima) colectadas en los valles andinos de la Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020-06)Squash landraces (Cucurbita maxima) are maintained by small farmers as a major nutritional food. Twenty seven of these landraces were collected in Argentinian Andean Valleys and morphologically characterized. Genetic ... -
Genetic relatedness and population structure within the public Argentinean collection of maize inbred lines
(2014)Genetic diversity of an Argentinean public temperate inbred maize collection has not been previously assessed. This collection includes mainly locally developed orange flint germplasm and a group of temperate inbred lines ... -
Genetic structure and domestication of carrot (Daucus carota subsp. sativus) (Apiaceae)
(2013-05)• Premise of the study: Analyses of genetic structure and phylogenetic relationships illuminate the origin and domestication of modern crops. Despite being an important worldwide vegetable, the genetic structure and ... -
Genetic variability for leaf growth rate and duration under water deficit in sunflower: analysis of responses at cell, organ, and plant level
(Oxford Academic Press, 2008-05)Plants under water deficit reduce leaf growth, thereby reducing transpiration rate at the expense of reduced photosynthesis. The objective of this work was to analyse the response of leaf growth to water deficit in several ... -
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 ... -
