Earliness per se variation in Argentine bread wheat varieties and mapping of QTLs in a recombinant inbred line population
Lombardo, Lucio; Ghione, Celina Elena; Nisi, María Mercedes; Tranquilli, Gabriela; Helguera, Marcelo (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 ... -
Effect of allelic variation at the Glu-3 / Gli-1 loci on breadmaking quality parameters in hexaploid wheat [Triticum aestivum L.]
Bonafede, Marcos; Tranquilli, Gabriela; Pfluger, Laura Alicia; Peña, Roberto Javier; Dubcovsky, Jorge (2015-03)Low molecular weight glutenin subunits (LMW-GS) encoded by the Glu-3 loci are known to contribute to wheat breadmaking quality. However, the specific effect of individual Glu-3 alleles is not well understood due to their ... -
Effect of the Hope FT-B1 Allele on wheat heading time and yield components
Nitcher, Rebecca; Pearce, Stephen; Tranquilli, Gabriela; Xiaoqin, Zhang; Dubcovsky, Jorge (2014-09)Precise regulation of flowering time is critical for plant reproductive success and, in cereals, to maximize grain yields. Seasonal cues including temperature and day length are integrated to regulate the timing of flowering. ... -
Genetic and physical mapping of the earliness perse locus Eps - Am1 in Triticum monococcum identifies early flowering 3 (ELF3) as a candidate gene
Tranquilli, Gabriela; Lewis, Silvina; Kippes, Nestor; Dubcovsky, Jorge; Alvarez, María Alejandra (2016-07)Wheat cultivars exposed to optimal photoperiod and vernalization treatments still exhibit differences in heading time. This variation, known as earliness per se (Eps), is important for the fine-tuning of flowering and the ... -
How does post-flowering sources/sink manipulation affect grain weight and commercial quality in Argentinean bread wheat genotypes with different baking aptitude?
Arata, Agustín Francisco; Lázaro, Laura; Tranquilli, Gabriela; Arrigoni, Adriana C.; Martínez, Mauro; Rondanini, Deborah Paola (Elsevier, 2023-06-29)Context: Wheat is a crop of vital importance for food security. In contrast to the accumulated knowledge for yield determination, the effect of variations in the source/sink (S/S) ratio on grain quality, and its interaction ... -
Incidence of nitrogen fertilization and nitrogen/sulfur complementary fertilization on protein accumulation, yield, and end‑use quality of bread wheat cultivars
Arrigoni, Adriana Cecilia; Lazaro, Laura; Rogers, William John; Arata, Agustín Francisco; Tranquilli, Gabriela (Springer, 2025-08-09)Wheat quality is determined by genotype, environment, and genotype x environment interaction.
