A greenhouse method to screen brachiariagrass genotypes for aluminum resistance and root vigor

Autor: Wenzl, Peter Arango Vélez, Adriana Chavez, Alba L. Buitrago González, M.E. Patino, GM Miles, John W. Rao, Idupulapati M.

Brachiaria species are widely sown on the infertile and Al-toxic soils of neotropical savannas. Breeding programs seek to combine edaphic adaptation with other traits in interspecific hybrids. Edaphic adaptation is difficult to assess because it is only manifest in pasture persistence across seve...

Identificación morfológica y molecular de Prosapia simulans (Walker) (Hemiptera: Cercopidae), y selección y mecanismos de resistencia este salivazo en híbridos de brachiaria = Morphological and molecular identification of Prosapia simulans (Walker) (Hemiptera: Cercopidae), and screening and mechanisms of resistance to this spittlebug in Brachiaria hybrids

Autor: Castro, U. Cardona Mejía, César Vera Graziano, J Miles, John W. Garza García, Ramón

Prosapia simulans (Walker) es una especie de salivazo que ataca los pastos del género Brachiaria (Trin.) Griseb. desde México hasta Colombia y ocasiona pérdidas económicas a la industria ganadera. El desarrollo de cultivares resistentes es considerado el mejor método de control del salivazo. Este...

Independence of Resistance in Brachiaria spp. to Nymphs or to Adult Spittlebugs (Hemiptera: Cercopidae): Implications for Breeding for Resistance

Autor: Cardona Mejía, César Miles, John W. Zuniga, G Sotelo, G.

Both nymphal and adult spittlebugs (Hemiptera: Cercopidae) cause serious economic damage to susceptible brachiariagrass [genus Biachiaria (Trin.) Griseb], pastures in tropical America. Both life stages are xylem feeders: nymphs feed primarily on roots and stems, whereas the adults feed mainly on ...

Biological nitrification inhibition activity in a soil-grown biparental population of the forage grass, Brachiaria humidicola

Autor: Nuñez, Jonathan Arévalo, Ashly Karwat, Hannes Egenolf, Konrad Miles, John W. Chirinda, Ngonidzashe Cadisch, Georg Rasche, Frank Rao, Idupulapati M. Subbarao, Guntur Arango, Jacobo

Aim: Utilization of biological nitrification inhibition (BNI) strategy can reduce nitrogen losses in agricultural systems. This study is aimed at characterizing BNI activity in a plant-soil system using a biparental hybrid population of Brachiaria humidicola (Bh), a forage grass with high BNI pot...

Recurrent selection in a synthetic brachiariagrass population improves resistance to three spittlebug species

Autor: Miles, John W. Cardona Mejía, César Sotelo, Guillermo

Spittlebugs (Homoptera: Cercopidae) are important pests of forage grasses in the genus Brachiaria (Trin.) Griseb. throughout the neotropics. Results of recurrent selection on resistance to spittlebugs in a synthetic brachiariagrass population are reported. The population was synthesized by recomb...

Advances in improving tolerance to waterlogging in Brachiaria grasses

Autor: Cardoso Arango, Juan Andrés Jiménez, Juan Rincón, Joisse Dayana Guevara, Edward D. Hoek, Rein van der Jarvis, Andy Peters, Michael Miles, John W. Ayarza, Miguel Angel Cajas, Socorro Rincón, Álvaro Mateus, Henry Quiceno, Jaime Barragán, Wilson Lascano, Carlos E. Argel M., Pedro J. Mena Urbina, Martin A. Hertentains, Luis Rao, Idupulapati M.

Poor drainage is found on about 11.3% of agricultural land in Latin America where physiography promotes flooding, high groundwater tables, or stagnant surface water (waterlogging). Waterlogging drastically reduces oxygen diffusion into the soil causing hypoxia which is the main limitation that re...
