Cultivation of resistant varieties with chemical control is highly effective against blast pathogens.Īli MA, Teli GN, Bhat GA, Parry, Wani SA. Knowledge on the virulence of the rice blast and host resistant is essential for managing the disease. grisea should be taken into account when screening blast resistant rice genotypes through morphological analysis, pathogenicity and molecular characterization. Rice breeders now have a number of resistant genes however, most of the breeding programs emphasized upon monogenic resistance. Only through pathogenicity research the pathotypes can be determined using a collection of different rice varieties that are usually different carrying various resistance genes. The virulent pathotypes cause severe disease incidence. During sexual hybridization, pathogenic changes may provide evidence of pathogenic variation found at the asexual stage of the fungus. The principal cause of resistance breakdown in rice against rice blast disease is pathogenic variability. Susceptible cultivars cause huge rice production loss in yield. The disease's occurrence and symptoms vary from country to country. The disease outbreak depends on the weather and climatic conditions of the various regions. Economically relevance with 60 percent of total population of world depending on rice as the main source of calories, may have destructive effects of the disease, however, this pathogen has developed into a pioneering model system for researching host-pathogen interactions. ![]() Rice blast caused by Magnaporthe grisea is the major damaging disease in nearly all rice growing nations. ![]()
