Brachiariagrass breeding programs are beginning to contribute to the array of available cultivars. In practical terms, the cultivars of koroniviagrass are easily distinguished from other brachiariagrass cultivars by their very strongly stoloniferous growth habit, narrow, wiry stems, and narrow, glabrous leaves. Apomictic reproduction and ploidy differences delayed the initiation of brachiariagrass breeding. The excellent adaptation of brachiariagrasses to low-fertility soils has encouraged their use for extensive, permanent pasture. Although several control methods are effective, host plant resistance is the only economically viable strategy owing to the large areas of brachiariagrass pastures and their low value per hectare. Growth pattern of the brachiariagrasses is cyclic and much or all forage tissue dies of natural senescence or insufficient water during the dry season. Production systems have intensified, particularly with the increasing use of agropastoral systems, leading to an increasing demand for higher quality forage grasses, even if they are more demanding of production inputs.
