The main insect pests and diseases associated with Brachiaria pastures are considered, with emphasis on spittlebugs, the most damaging pests in tropical America. Outbreaks of the polyphagous burrowing bugs of the genus Scaptocoris, both in Brazil and Colombia, are of concern. Other pests discusse...

Brachiaria grasses, especially R decumbens cv. Basilisk (signalgrass), are the most widely grown pastures in subhumid and humid tropics. When fertilized with nitrogen and well managed, these pastures have high forage quality (measured as digestibility). Animal production is therefore high and rel...


Lascano, Carlos E.Euclides, Valéria Pacheco Batista[Nutritional quality and animal production of Brachiaria pastures]Nutritional quality and animal production of Brachiaria pastures

Two essentials for breeding new cultivars of Brachiaria are germplasm diversity and information on basic biological aspects of major species. This paper reviews current knowledge on the cytological behavior, mode of reproduction and its inheritance, and crossing compatibility of different species...


Valle, Cacilda Borges doSavidan, Yves H.[Genetics, cytogenetics, and reproductive biology of Brachiaria]Genetics, cytogenetics, and reproductive biology of Brachiaria

Seed of six commercial Brachiaria species is extensively produced for pasture sowing. Production is restricted geographically and seasonally by photoperiodic flowering reactions. It also requires a prior control of vegetative tiller production, and therefore a reliable dry season. The necessary c...


Hopkinson, J.M.Souza, Francisco Humberto Dübbern de[Reproductive physiology, seed production, and seed quality of Brachiaria]Reproductive physiology, seed production, and seed quality of Brachiaria

Until 10 years ago, genetic improvement of Brachiaria species depended entirely on selection among naturally existing genotypes, genetic recombination being impossible because of prevailing apomictic reproduction. However, recent advances in understanding the genetics and cytogenetics of Brachiar...


Miles, John W.Valle, Cacilda Borges do[Manipulation of apomixis in Brachiaria breeding]Manipulation of apomixis in Brachiaria breeding

This paper reviews published and unpublished information on the physiological and agronomic characteristics associated with the widespread adaptation of Brachiaria species. Adaptation to shade, drought, flooding, rainfall, and defoliation are discussed. Strong regrowth under frequent defoliation ...


Fisher, Myles J.Kerridge, Peter C.[The agronomy and physiology of Brachiaria species]The agronomy and physiology of Brachiaria species

Brachiaria cultivars developed by forage research programs are delivered to commercial livestock producers through the vehicle of seed. Over the past 15-20 years, a large, dynamic industry has developed in Brazil for the production of Brachiaria seed. This paper describes the history of this indu...

Se presentan los resultados de las actividades de multiplicacion de semilla exptl. y basica de pastos tropicales en las regiones de Pucallpa, Tarapoto y Puerto Maldonado (Peru) durante 1987-88, y se explican los principales factores que impidieron el cumplimiento de los objetivos propuestos. Se e...

We reviewed 97 species of the genus Brachiaria, spanning the whole taxon. The species were arranged in groups according to perceived natural affinities. The morphology of the inflorescence, especially the spikelet, was examined in detail and found to be highly variable; accordingly, the number of...
