![]() ![]() This family can be used to produce a frame genetic map and identify water stress tolerance major genes. Controlled crosses were conducted in order to establish a pseudo-testcross population including 800 F1 individuals, with potential to be extended to 2000 ones. Two polymorphic cultivars with contrasting hydric-stress tolerance were selected. The aim of this work is the construction of an Ilex paraguariensis genetic map to be used in molecular breeding. In the commercial plantations, individuals show low growth efficiency, being a limited hydric stress tolerance one of the main limitations for primary production. The exploitation of Ilex paraguariensis has economical and strategic impact for several South-american countries, like Argentina, Brasil, Paraguay and Uruguay. It is widely used in the preparation of a tea-like regional infusion known as “mate” or “mate-tea”. Ilex paraguariensis Saint Hilaire is a species originary from South America. This collaboration was entirely granted by the National Institute of Yerba Mate (INYM). It was the fruit of cooperation between the Faculty of Agricultural Sciences, National University of Rosario and the Faculty of Agricultural Sciences, National North-East University-IBONE, CONICET. This development was carried out by doctors Olsina C, Cairo C, Pessino SCĭevelopment of an Ilex paraguariensis (yerba mate) core genetic map with molecular breeding purposesĬurrently, this project is in its final stage of implementation (4th stage out of 4 total stages). ![]() This genetic database is now used by the Rosario Stock Exchange to provide a genotype classification service. A subset of 20 highly-informative SSR markers was selected to achieve an effective discrimination of any databank accession by means of a simple and efficient procedure, in order to be used for rapid identification analysis and differentiation of new cultivars. It was aimed at developing a genetic database based on SSR (Simple Sequence Repeats, or Microsatellites) and AFLP (Amplified Fragment Length Polymorphisms) markers, to characterize the argentine soybean germplasm, allow cultivar identification and provide assistance to breeding. This work was the result of cooperation between the Rosario Stock Exchange (Bolsa de Comercio de Rosario) and the Faculty of Agricultural Sciences of the National University of Rosario (Facultad de Ciencias Agrarias de la Universidad Nacional de Rosario).
