摘要
草原草(Bromus catharticus Vahl)是阿根廷温带气候中最重要和最广泛的一年生/二年生原生牧草。对草原草品种和本地居群形态生理性状的表型变异进行了研究。第一批商业品种是异种种群,被认为是最适合阿根廷温带地区的。通过对选育基础群体和保存在INTA Pergamino活性库中的种质的遗传、农艺和分子特征的分析,有助于了解和保护可利用的遗传多样性,同时为育种提供可利用的遗传变异。本研究中最具代表性的品种为Pergamino Martín Fierro MAG;Fierro Plus INTA, Bar INTA 200, Rosalía INTA和INTA Calvu,其中开发了与动物生产利用相关的技术包。关键词:草原草,品种,种质,植物育种
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 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.
