In Brazil, milk production is practiced by more than one million farmers, mostly smallholders, who have the most important sources of feed for the herd in pasture and forage grass cropping for cut-and-carry. One of the major demands of farmers is on improved forage cultivars for cutting and grazing that can meet the nutritional needs of herds throughout the year. Elephantgrass, in addition to its superior performance in the establishment of cut-and-carry plantations (i.e. green chopped, hay, and silage) for yielding supplemental roughage during the dry season, has great potential for use in rotational grazing systems. The deficiencies of elephantgrass as a forage crop are, among others, vegetative propagation, difficulty of management under grazing management and susceptibility to spittlebugs. The objective of this project was to obtain improved cultivars of elephantgrass for grazing or cutting systems, propagated by seeds and adapted to different Brazilian soil and climatic conditions. The work carried out in the project was comprised of breeding of new genotypes, selection genotypes tolerant to biotic and abiotic stresses, and the National Network of Evaluating Elephantgrass (Renace). The project generated improved cultivars of elephantgrass for cutting and grazing (BRS Canará and BRS Kurumi), adapted to several Brazilian regions, contributing to stabilize the availability of good nutritional quality forage throughout the year, with favorable consequences on the reduction of production costs and on the increase of animal productivity. The partner institutions of the project were the Mato Grosso Company of Research, Assistance and Rural Extension; Agricultural Research Company of Rio Grande do Norte; Capixaba Institute for Research, Technical Assistance and Rural Extension; Company of Agricultural Research and Rural Extension of Santa Catarina; São Paulo Agribusiness Technology Agency; Agronomic Institute of Pernambuco; Federal University of Rio Grande do Norte; Federal University of Mato Grosso; Universidade Estadual do Norte Fluminense Darcy Ribeiro; Federal Rural University of Pernambuco and Vale do Rio Doce University.
