Genetic analysis of F₂ population from crosses between Pongsu Seribu 2 and MR264 on blast disease / Norain Mohd Nor

Rice blast caused by Magnaporthe oryzae is one of the most destructive diseases in rice production. Significant yield losses and decreasing rice productivity have become a major concern in rice breeding. Plant host disease is the most strategic and economical approach to control this disease. Crosses between Pongsu Seribu 2, a traditional resistant variety and MR264, a high yielding but susceptible to blast disease was developed to improvise new lines. About 157 SSR markers were used to identify the polymorphism between parental lines.
