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. ...

Dinámicas campesinas y fitomejoramiento participativo: el caso de los sorgos blancos (Sorghum bicolor, L. Moench) en la región norte de Nicaragua. En las regiones secas de Nicaragua, los sorgos blancos representan un grano básico cada vez más importante para las familias campesinas pobres. Desde ...

Common bacterial blight (CBB) is the most serious bacterial disease of common bean in Uganda. It causes severe yield losses of up to 62%. Genetic resistance is the most effective option for controlling CBB in smallholder common bean production systems. This study was carried out to determine the ...

Postharvest root deterioration or vascular streaking of cassava clones (accessions and breeding lines) was evaluated with harvests at different ages (8 and 12 mo.), seasons (beginning and end of wet season), and locations (CIAT-Palmira, Carimagua, and Caribia in Colombia) to assess the effect of ...

The genetic improvement of drought resistance is essential for stable and adequate crop production in drought-prone areas1. Here we demonstrate that alteration of root system architecture improves drought avoidance through the cloning and characterization of DEEPER ROOTING 1 (DRO1), a rice quanti...
