Background: Developing new population types based on interspecific introgressions has been suggested by several authors to facilitate the discovery of novel allelic sources for traits of agronomic importance. Chromosome segment substitution lines from interspecific crosses represent a powerful an...

Rice sheath blight (ShB), caused by the soilborne pathogen Rhizoctonia solani, annually causes severe losses in yield and quality in many rice production areas worldwide. Jasmine 85 is an indica cultivar that has proven to have a high level of resistance to this pathogen. The objective of this st...

El añublo del arroz causado por Pyricularia grisea (Magnaporthe grisea) es el principal limitante de la producción en Colombia. La perdida de la resistencia ocurre en penodos de uno a tres años, con la excepción de los cultivares Oryzica Llanos 5 liberado en 1989 y Fedearroz 50 liberado en 1998. ...
