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...

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...

Autor: Correa Victoria, Fernando J. Zeigler, Robert S.

Two sets of experiments were conducted to compare the relative stability of partial and complete resistance in rice to Pyricularia grisea (causal agent of the rice blast disease) in a disease hot spot in eastern Colombia. In the first set of experiments, 186 breeding lines selected at the site ...
