Abstract
cultivar was based on mass selection over 5 years, followed by evaluation of environmental adaptation in pure stands and in mixed pastures in the western Brazilian Amazon. During the evaluation process, selection was performed to improve speed of establishment, dry matter yield, nutritive value and seed production. Evaluations also occurred under rotational grazing in mixed pastures with Cynodon nlemfuensis, Brachiaria brizantha and B. humidicola, in intensive systems. The new cultivar was registered with the Ministry of Agriculture, Livestock and Food Supply of Brazil in 2008 and its protection process was finalized in 2011, after conducting tests for distinctness, homogeneity and stability. While developing the cultivar, the semi-mechanized seed production system of forage peanut was also established (Assis et al. 2011) .
Highlights
Forage peanut (Arachis pintoi) is a forage legume of relatively recent use in beef and dairy cattle feeding
In the state of Acre, western Brazilian Amazon, 137,000 ha are cultivated with forage peanut, cv
Despite the success achieved in mixed pastures with forage peanut, expansion of the area sown has been relatively slow because vegetative propagation using stolons is labor-intensive and requires large quantities of limited vegetative material
Summary
Forage peanut (Arachis pintoi) is a forage legume of relatively recent use in beef and dairy cattle feeding. Forage peanut has a great number of favorable attributes for establishing grass-legume mixtures, which guarantee the persistence and high yields of high quality forage in cultivated pastures. Studies with this species have intensified in many tropical regions of the world (Assis and Valentim 2009). In Brazil, Embrapa has coordinated the development of new forage peanut cultivars and their evaluation in different biomes. The objective of this work is to present a new cultivar of forage peanut propagated by seeds, developed by Embrapa for use in tropical regions, in partnership with Unipasto (Association for Promotion of Forage Breeding Research)
