THE GENETIC IMPROVEMENT OF PRAIRIE GRASS (Bromus catharticus Vahl) IN ARGENTINA: SYNTHESIS OF ACHIEVEMENTS AND ADVANCES

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