          Abstract

          RESUMEN La cebadilla criolla (Bromus catharticus Vahl) es la gramínea forrajera nativa anual/bianual de clima templado de mayor importancia y difusión en la Argentina. Varios autores han estudiado la variabilidad fenotípica en caracteres morfofisiológicos en cultivares y poblaciones nativas de cebadilla criolla. Las primeras variedades cultivadas comerciales de cebadilla criolla, eran poblaciones heterogéneas a las que se las consideraba de mejor adaptación a toda la región de cultivo. Con los estudios de caracterización genética, agronómica y molecular de las poblaciones base de selección y del germoplasma conservado en el banco activo de INTA Pergamino, se contribuyó a conocer y conservar la diversidad genética disponible y al mismo tiempo, disponer de variabilidad genética utilizable en programas de mejoramiento. Los cultivares públicos más representativos considerados en este trabajo fueron: Pergamino Martín Fierro MAG, Fierro Plus INTA, Bar INTA 200, Rosalía INTA e INTA Calvu, en los que se desarrollaron paquetes tecnológicos asociados a la utilización en producción animal.

          ABSTRACT The prairie grass (Bromus catharticus Vahl) is the annual/biennial native forage grass of temperate climates of most importance and diffusion in Argentina. Several authors have studied the phenotypic variability in morphophysiological characters in cultivars and native populations of prairie grass. The first commercial cultivars were heterogeneous populations that were considered the best adapted in the temperate region of Argentina. Genetic, agronomic and molecular characterization of the selection base populations and of the germplasm conserved in the active bank of INTA Pergamino, contributed to knowing and conserving the available genetic diversity and, at the same time, provided usable genetic variability in breeding. The most representative cultivars considered in this work were Pergamino Martín Fierro MAG; Fierro Plus INTA, Bar INTA 200, Rosalía INTA and INTA Calvu, in which technological packages associated with the utilization in animal production were developed.

          Metabolomics-assisted breeding: a viable option for crop improvement?

          Metabolomics approaches enable the parallel assessment of the levels of a broad range of metabolites and have been documented to have great value in both phenotyping and diagnostic analyses in plants. These tools have recently been turned to evaluation of the natural variance apparent in metabolite composition. Here, we describe exciting progress made in the identification of the genetic determinants of plant chemical composition, focussing on the application of metabolomics strategies and their integration with other high-throughput technologies. Metabolomics represents an important addition to the tools currently employed in genomics-assisted selection for crop improvement.
