Description
Setaria sphacelata (Schumach.) Stapf & C.E. Hubb is a highly productive warm-season grass that has been eva-luated in Uruguay since the 1970s (Mas 2007). It is one of the most productive and promising subtropical grasses for the Uruguayan climatic conditions. Some of the most re-markable attributes of interest are its palatability, ease to establish from seed, highly persistent, adapted to a wide range of soils, and some frost tolerance. Cultivars ‘Narok’ and ‘Kazungula’ were the only materials evaluated and no genetic improvement was conducted in Uruguay. These cultivars present some limitations, such as low seed yields and quality, and susceptibility to low temperatures. Look-ing to overcome these limitations, a germplasm collection from the USDA was introduced to Uruguay to explore the genetic variability and start a breeding program.
