Hypothesis of the exclusion of lineages as an alternative for the development of rice cultivars with durable resistance to Pyricularia grisea (Sacc) in Colombia



Hypothesis of the exclusion of lineages as an alternative for the development of rice cultivars with durable resistance to Pyricularia grisea (Sacc) in Colombia



Fitopatologia Colombiana 23(1/2): 54-58



Rice blast caused by the fungus Pyricularia grisea is the most important disease of rice crops throughout the world. The development of resistant varieties is the method preferred for the control of the disease; however, varieties tend to become susceptible in periods ranging from one to two years after their deployment. The great variability of the pathogen is mentioned as the cause of the breaking down of the resistance.
