Candidate Gene Approach for Parasite Resistance in Sheep – Variation in Immune Pathway Genes and Association with Fecal Egg Count
(Plos One, 2014-02-12)Sheep chromosome 3 (Oar3) has the largest number of QTLs reported to be significantly associated with resistance to gastro-intestinal nematodes. This study aimed to identify single nucleotide polymorphisms (SNPs) within ... -
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 ... -
Diversidad genómica y mapeo por asociación para la resistencia a la podredumbre húmeda del capítulo causada por Sclerotinia sclerotiorum en girasol
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2015)Argentina tiene una larga tradición en el mejoramiento de girasol, siendo su germoplasma un recurso genético invaluable a nivel mundial. Nuestro país es el tercer exportador mundial de aceite crudo y segundo exportador de ... -
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 ... -
