Ninety-five strains of fluorescent (presumed to be Pseudomonas spp.) and nonfluorescent pathogens of rice causing grain and sheath rot, dirty panicle, and manchado de grano, and 21 strains of nonpathogenic fluorescent pseudomonads isolated from rice grain and sheaths from 22 countries were compar...

We determined DNA fingerprints and pathotypes on international differentials for 151 isolates of the rice blast fungus Pyricularia grisea that were collected from 15 rice cultivars at a blast disease breeding nursery in Santa Rosa, Colombia. The pathogen population expressed an extraordinarily hi...

Many types of symptoms associated with discolored grain have been observed on rice (Oryza sativa) sheaths, leaves, and grain in Mexico, Guatemala, Panama, Surinam, Colombia, Peru, and Brazil. These include brown necrotic lesions ranging from small specks to large brown to maroon sheath blotches. ...

Crosses were made between Fanny (highly susceptible to blast) and 11 cultivars differing in blast resistance. Using the pedigree method (PM) segregating generations were evaluated and selected for blast resistance. Via anther culture (AC), doubled-haploids were obtained from F1 plants and from F2...

The inheritance of the ability of Sogatodes oryzicola to support replication of the rice hoja blanca virus (RHBV) was studied by following the segregation of progeny of crosses between insects of known pedigree and known ability to support virus replication and transmission. Virus transmission to...
