(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2013-03)La papa (Solanum tuberosum ssp. tuberosum) es el tercer cultivo más importante y la dicotiledónea de mayor importancia en la alimentación. El estrés hídrico es la mayor limitante de la producción. En respuesta a la sequía ... -
Cartografiado de QTL y genes candidatos asociados a metabolitos determinantes de la calidad de fruto en melocotón
(2013)Tradicionalmente los programas de mejora del melocotón (Prunus persica (L.) Batsch) se centraron fundamentalmente en la obtención de genotipos elite de alta productividad, resistentes a plagas y patógenos, adaptados a ... -
Dissecting genetic loci of yield, yield components, and protein content in bread wheat nested association mapping population
(Springer, 2023-05)In the last century wheat breeding programs have shown consistent yield increases, often associated with lower grain protein concentrations (GPC). A better understanding of the genetic basis of grain yield and grain protein ... -
Earliness per se variation in Argentine bread wheat varieties and mapping of QTLs in a recombinant inbred line population
(Springer, 2019-10)The occurrence of flowering time in wheat is affected not only by the vernalization and photoperiod response, but also by earliness per se (EPS). The effects of this trait facilitate the fine tunning of the life cycle for ... -
Estudio de la arquitectura genética del duraznero a través de la identificación de loci de caracteres cuantitativos utilizando análisis de genoma completo para múltiples caracteres agronómicos
(REDBIO Argentina, 2023-06)La disminución en los costos de secuenciación (Next Generation Sequencing) desplegó un amplio abanico de posibilidades en estudios genómicos. La identificación de marcadores moleculares (MM) asociados a caracteres de ... -
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 variation in fire recovery and other fire‑related traits in a global eucalypt species
(Springer, 2022-11-12)To understand the potential of forests to adapt to wildfire, we studied the genetic architecture of fire-related structural, damage and recovery traits in a globally important Australian forest tree species, Eucalyptus ... -
Identification and validation of QTL for spike fertile floret and fruiting efficiencies in hexaploid wheat (Triticum aestivum L.)
(Springer, 2020-06)The spike fruiting efficiency (FE—grains per unit spike dry weight at anthesis, GN/SDW) is a promising trait to improve wheat yield potential. It depends on fertile floret efficiency (fertile florets per unit SDW—FFE, ... -
Kernel weight in maize: genetic control of its physiological and compositional determinants in a dent × flint-caribbean RIL population
(Maydica-ist Sper Cerealicoltur, 2016-12)The genetic control of maize kernel weight (KW) determination could be studied through its physiological and/ or compositional determinants. Our objective was to dissect the genetic control of maize KW by analyzing its ... -
Maize Nitrogen Use Efficiency: QTL Mapping in a U.S. Dent x Argentine-Caribbean Flint RILs population
(2018-04)This study was aimed to identify quantitative trait loci (QTL) for nitrogen use efficiency (NUE) and related traits in a maize population derived from a cross between two lines with different genetic background (B100 and ... -
Mapeo de QTL asociados a caracteres de arquitectura de canopeo en maíz (Zea mays L.)
(2017-09)En condiciones de alta productividad el rendimiento en maíz es altamente dependiente de la presencia de una fuente fotosintética suficiente para la obtención de un alto número de granos por unidad de superficie y para el ... -
