Identification of new sources of resistance to RHBV- rice hoja blanca virus
With the aim to find new sources of resistance to rice hoja blanca (white leaf) disease, transmitted by the insect Tagosodes orizicolus, 660 genotypes were evaluated under greenhouse and field conditions. Seven resistant genotypes were identified, and genomic studies were performed to demonstrate th...

| description | With the aim to find new sources of resistance to rice hoja blanca (white leaf) disease, transmitted by the insect Tagosodes orizicolus, 660 genotypes were evaluated under greenhouse and field conditions. Seven resistant genotypes were identified, and genomic studies were performed to demonstrate that the resistance in these sources is genetically different from that of Fedearroz 2000, which is currently the variety with the most resistance to hoja blanca. These new resistance sources constitute a resource that can be used to sustainably extend hoja blanca disease management throughout all of the rice-growing regions of tropical America. This is the first report of hoja blanca resistance in indica rice and different from that of Fedearroz 2000. |

Con el objetivo de encontrar nuevas fuentes de resistencia a la enfermedad de la hoja blanca del arroz, transmitida por el insecto Tagosodes orizicolus, se evaluaron 660 genotipos en condiciones de invernadero y campo. Se identificaron siete genotipos con resistencia a la enfermedad y se realizaron estudios del genoma para evidenciar que eran genéticamente diferentes a Fedearroz 2000, la variedad de mejor comportamiento ante el virus, en el momento. Estas nuevas fuentes de resistencia constituyen un recurso que puede utilizarse para extender un manejo sostenible de la enfermedad, en todas las regiones productoras de arroz en América tropical. Este es el primer reporte de fuentes de resistencia, tipo indica, diferentes a Fedearroz 2000. 2018 2018-05-25T20:00:02Z 2018-05-25T20:00:02Z Journal Article https://hdl.handle.net/10568/92927 en Open Access Universidad Nacional de Colombia Cruz-Gallego, Maribel, Rebolledo, Maria Camila, Cuasquer, Juan, Cruz, Daniel, Peña-Fernández, Alexandra Lorena, Quintero, Constanza, Silva-Córdoba, Alexander, Alvarez, María Fernanda, Jojoa-Cruz, Sebastián, Lorieux, Mathias, Stuart, Jeffrey J., Correa, Fernando.
