Rao, Idupulapati M.Miles, John W.Granobles, Juan Carlos[Differences in tolerance to infertile acid soil stress among germplasm accessions and genetic recombinants of the tropical forage grass genus, Brachiaria]Differences in tolerance to infertile acid soil stress among germplasm accessions and genetic recombinants of the tropical forage grass genus, Brachiaria

Several species and genera of spittlebugs (Homoptera: Cercopidae) are economic pests of grasses in tropical America. They have the potential to cause serious losses on millions of hectares of improved pastures based on cultivars of several species of Brachiaria. Most of the available commercial c...

Research aimed at developing various Stylosanthes species as forage crops in South America began with the collection of Brazilian germplasm in the 1960s. These efforts have intensified greatly in the past 25 years with the participation of a number of local, national and international institution...

La generación e identificación de híbridos de Brachiaria spp. con altos niveles de resistencia a Aeneolamia varia (F.) y la caracterización de los mecanismos de resistencia a otras especies de salivazo, son aspectos muy importantes en un programa de mejoramiento de forrajes que se basa en el sigu...

Up to 50% of Brachiaria production in the tropics is affected by foliar blight caused by Rhizoctonia spp. Monothallic isolates of Rhizoctonia (n = 147) were cultured from different Brachiaria genotypes in Colombia and morphologically characterized and evaluated in pathogenicity trials in the gree...

An inter-institutional and multi-disciplinary project to identify Brachiaria genotypes, which combine waterlogging tolerance with high forage yield and quality, for use in agricultural land in Latin America with poor drainage, is underway. The aim is to improve meat and milk production and mitiga...

Several genera and species of spittlebugs (Homoptera: Cercopidae) are economic pests of Brachiaria spp. grasses in tropical America. To support current breeding programs aimed at obtaining multiple spittlebug resistance, we undertook a series of studies on antibiosis and tolerance as possible mec...
