Sheep fescue (Festuca ovina L. sensu lato) is distinguished for its ability to form sods on difficult sites (Dernoeden et al. 1994). This species is a persistent bunch grass that mixes well with wildflowers, without dominating them. For this reason sheep fescue can play an important role in the creation of landscape lawns. In the adaptation of this grass to extremely difficult sites, specific biological features of this grass are very important, especially water efficiency, drought tolerance, and low fertilizer requirements (Aronson et al. 1987; Brar and Palazzo, 1995).
The aim of this work was to …

Two strategies have been used in the breeding of Brachiaria (syn. Urochloa) to produce new cultivars. The first involves exploring the natural variability existing in nature, which is the selection of ecotypes, mostly apomicts, from the diversity in germplasm banks. This strategy proved efficient originally and the cultivars in use in Brazil were derived in this way, but progress with this strategy is limited in the medium to long term.

Pastures of Brachiaria decumbens cv. Basilisk radically changed the scenario of livestock production in central Brazil in the early 1970s and in fact, promoted the development of this vast region. However, despite the reasonable biomass yields and nutritional value when grown on these tropical acid soils, its susceptibility to grassland spittlebugs has limited its use. The breeding of B. decumbens in Brazil has been restricted to interspecific crosses using cv. Basilisk as a pollen donor due to the lack of compatible sexual ecotypes within this species. Recently, the successful chromosome duplication of a sexually reproducing diploid accession produced 3 successful …
