Genetic structure of Argentinean hexaploid wheat germplasm
(2013-05)The identification of genetically homogeneous groups of individuals is an ancient issue in population genetics and in the case of crops like wheat, it can be valuable information for breeding programs, genetic mapping and ... -
Identification and characterization of Rht25, a locus on chromosome arm 6AS affecting wheat plant height, heading time, and spike development
(2018)Understanding genes regulating wheat plant height is important to optimize harvest index and maximize grain yield. In modern wheat varieties grown under high-input conditions, the gibberellin-insensitive semi-dwarfing ... -
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, ... -
Identification of novel high molecular weight glutenin subunit mutants in bread wheat (Triticum aestivum L.)
(2017-07)Bread wheat (Triticum aestivum L.) is a staple food crop eaten in different ways like pan and other food products. High molecular weight glutenin subunits (HMW-GS) are major determinants of the different wheat end-use ... -
Incidencia de fusariosis de la espiga en cultivares de trigo pan durante 2012-13 en Marcos Juárez (Córdoba–Argentina)
(2015)En 2012 se caracterizaron cultivares de trigo frente a ataques severos de Fusariosis de la es-piga en Marcos Juárez en ensayos de RET y bajo infección artifi cial. Se determinó incidencia, severidad rendimiento de ... -
Influence of cultivar and environment on quality of Latin American wheats
(2012-09)Wheat consumption is growing, with processors asking for wheat-based products showing better and more consistent quality. Genotype, environment and their interaction (G × E) play an important role in the final expression ... -
Influencia de la freática sobre el rendimiento de trigo en la Región Sur de Córdoba
(Asociación Argentina de la Ciencia del Suelo (AACS), 2024-05-07)El beneficio de la capa freática está condicionado a la oscilación de la profundidad de la misma, por lo cual, es altamente importante comprender la relación entre la profundidad de la capa freática, el crecimiento del ... -
Influencia de la textura del grano de trigo (Triticum aestivum L.) sobre la calidad industrial de galletitas dulces y crackers
(2016-11-25)El sistema de comercialización de trigos establece una clasificación de los trigos hexaploides (Triticum aestivum L.) basada en la textura del endosperma que junto con la fuerza del gluten determinan sus potenciales usos ... -
An integrated dual strategy to control Fusarium graminearum sensu stricto by the biocontrol agent Streptomyces sp. RC 87B under field conditions. Reprint
(2017-03)Fusarium head blight (FHB) caused by species within the Fusarium graminearum complex is a devastating disease that causes extensive yield and quality losses to wheat in humid and semi-humid regions of the world. The disease ... -
