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...

A survey of the genetic diversity among the major cuban rice cultivars was conducted using isozyme, RAPD and AFLP markers. Polymorphisms were detected for esterases, peroxidases, alcohol dehydrogenases and polyphenoloxidases systems; 21 RAPD primers and four AFLP primer combinations. Heterozygosi...

The genetic structure of rice blast pathogen populations was studied using 149 and 107 monoconidial isolates from Los Palacios and Sur del Jíbaro rice production locations in the western and central regions of Cuba, respectively. These isolates were collected from 35 rice genotypes and total DNA ...

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. ...
