Dissecting genetic loci of yield, yield components, and protein content in bread wheat nested association mapping population
Donaire, Guillermo Manuel; Vanzetti, Leonardo Sebastian; Conde, María Belén; Bainotti, Carlos Tomas; Mir, Leticia Raquel; Borrás, Lucas; Chicaiza, Oswaldo; Helguera, Marcelo (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
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 high molecular weight glutenins and rye translocations on soft wheat flour cookie quality
Moiraghi, Malena; Vanzetti, Leonardo Sebastian; Pfluger, Laura Alicia; Helguera, Marcelo; Pérez, GabrielaTeresa (2013-11)The influence of high molecular weight glutenin subunits (HMW-GS) on wheat breadmaking quality has been extensively studied but the effect of different Glu-1 alleles on cookie quality is still poorly understood. This study ... -
Effect of Vrn-1, Ppd-1 genes and earliness per se on heading time in Argentinean bread wheat cultivars
Gomez, Dionisio Tomas; Vanzetti, Leonardo Sebastian; Helguera, Marcelo; Lombardo, Lucio; Fraschina, Jorge Alberto; Miralles, D.J. (2014-03)Predicting phenology, in particular heading time, is crucial to avoid and/or minimize risk of damage of frost, drought and high temperatures during grain filling. Although some of the major genes controlling development, ... -
Evaluación fenotípica y molecular de alelos de los genes Ppd-1 en una población biparental de trigo pan
Lombardo, Lucio; Nisi, María Mercedes; Ghione, Celina Elena; Fisore, G.D.; Helguera, Marcelo (2017-11)El constante incremento de las temperaturas –como consecuencia del cambio climático– en las regiones donde se cultiva trigo, exige ajustar el ciclo del cultivo a períodos más cortos para evitar o disminuir los estreses ... -
Genetic structure of Argentinean hexaploid wheat germplasm
Vanzetti, Leonardo Sebastian; Yerkovich, Nadia; Chialvo, Eugenia; Lombardo, Lucio; Vaschetto, Luis; Helguera, Marcelo (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
Youngjun Mo; Vanzetti, Leonardo Sebastian; Hale, Iago; Spagnolo, Emiliano J.; Guidobaldi, Fabio; Al-Oboudi, Jassim; Odle, Natalie; Pearce, Stephen; Helguera, Marcelo; Dubcovsky, Jorge (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 of leaf rust resistance genes in selected Argentinean bread wheat cultivars by gene postulation and molecular markers
Vanzetti, Leonardo Sebastian; Campos, Pablo Eduardo; Demichelis, Melina; Lombardo, Lucio; Aurelia, Paola Romina; Vaschetto, Luis María; Bainotti, Carlos Tomas; Helguera, Marcelo (Pontificia Universidad Católica de Valparaíso, 2011)Leaf rust, caused by Puccinia triticina Eriks. is a common and widespread disease of bread wheat (Triticum aestivum L.), in Argentina. Host resistance is the most economical, effective and ecologically sustainable method ... -
Identification of novel high molecular weight glutenin subunit mutants in bread wheat (Triticum aestivum L.)
Lombardo, Lucio; Nisi, María Mercedes; Salines, Nicolas; Ghione, Celina Elena; Helguera, Marcelo (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 ... -
MITE Tracker : an accurate approach to identify miniature inverted-repeat transposable elements in large genomes
Crescente, Juan Manuel; Zavallo, Diego; Helguera, Marcelo; Vanzetti, Leonardo Sebastian (BioMed Central, 2018)Background: Miniature inverted-repeat transposable elements (MITEs) are short, non-autonomous class II transposable elements present in a high number of conserved copies in eukaryote genomes. An accurate identification ... -
MS INTA 416 : a new Argentinean wheat cultivar carrying Fhb1 and Lr47 resistance genes
Bainotti, Carlos Tomas; Lewis, Silvina; Campos, Pablo Eduardo; Alberione, Enrique Javier; Salines, Nicolas; Gomez, Dionisio Tomas; Fraschina, Jorge Alberto; Salines, Jose Hector; Formica, Maria Beatriz; Donaire, Guillermo Manuel; Vanzetti, Leonardo Sebastian; Lombardo, Lucio; Nisi, María Mercedes; Cuniberti, Martha Beatriz; Mir, Leticia Raquel; Conde, María Belén; Helguera, Marcelo (2017-09)MS INTA 416 is a hard red winter wheat selected for high yield potential and good bread-making quality, combined with moderate resistance to Fusarium-head-blight and high resistance to leaf-rust, due mainly to presence of ... -
