The present work was conducted to identify microsatellite markers linked to the rice blast resistance gene Pi-1(t) for a marker-assisted selection program. Twenty-four primer pairs corresponding to 19 microsatellite loci were selected from the Gramene database (www. gramene.org) considering their...

Panicle blight of rice, caused by Burkholderia glumae, has been a serious problem on rice in Japan since 1955. It has been reported from other rice-producing countries around the world and recently was reported on rice in the southern United States (2). A rice producer in Panama contacted us to v...

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...

Silicon (Si) has been shown to suppress diseases of rice such as blast when applied to Si-deficient soils. In 1995 and 1996, Si was applied at 1,000 kg ha-1 to at two locations in eastern Colombia to determine if Si combined with reduced rates of fungicide could be used to manage leaf and neck bl...

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...

Forty-five international races of Pyricularia grisea, representing all nine race groups, were identified in a "hot spot" breeding site (Santa Rosa) in Colombia, with the largest number included in the IA group. The international race system did not fully describe the virulence spectrum of the iso...
