Answer:
➡️Rice blast, caused by the hemibiotrophic fungus Magnaporthe oryzae, is one of the most potent threats to rice production and causing tremendous yield loss. In the present study, seventy-one M. oryzae isolates were collected from three states of eastern India. Based on colony color, the blast isolates were grouped in five; grayish (11), grayish black (9), grayish white (19), blackish (20) and white (12). Most of the isolates were smooth (60) and few were rough (11) in colony appearance. The blast isolates produced characteristic spindle shaped symptoms on susceptible plant.Five isolates were recorded as highly virulent, eight as moderately virulent isolates and only two isolates wereobserved as mild isolates. The sequence similarities among fifteen M. oryzae isolates varied from 78 to 98.8%. The phylogenetic analysis showed uniform distribution of 71 blast isolates into two clusters and indicated
