The genus Pyricularia includes species that are pathogenic on a wide range of monocot plants. For example, Pyricularia oryzae (sexual morph Magnaporthe oryzae), the causal agent of the rice blast disease, is one of the most widely distributed diseases of rice, and is highly destructive leading to up to 30% yield loss worldwide.

In the present study, twenty isolates of M. oryzae were categorized into three groups based on colony colour i.e., greyish blackish, greyish and white, and in two group based on the texture of the.

Pyricularia oryzae (Magnaporthe oryzae), a causal agent of blast diseases on staple gramineous crops, is a model organism listed as the most important economically and scientifically of the top 10 fungal pathogens by fungal molecular pathologists.
JIRCAS, through its project titled “Blast Research Network for Stable Rice Production,” has clarified the diversity of blast (Pyricularia oryzae Cavara) races and the genetic variation of resistance in rice (Oryza sativa L.) cultivars of Asia and Africa. To develop a durable protection system against blast disease, which has caused serious damage to rice production in all rice.

The fungus Pyricularia oryzae (syn: Magnaporthe oryzae) causes the highly destructive rice blast disease, which is found in at least 85 countries worldwide 3. The effects of the fungus are so severe with approximately 30% of rice production losses globally that it was placed first in a list of the top ten fungal plant pathogens 4.

Recent studies concerning comparative genomics reveal that parasexual recombination may play important role in the evolution of rice blast fungus. To observe the parasexualism of rice blast (Pyricularia oryzae) and crabgrass blast (Pyricularia grisea) fungus double inoculation and punch method were applied in this experiment.
Magnaporthe oryzae (anamorph: Pyricularia grisea) also known as rice blast fungus is an important plant pathogen isolated from rice and a variety of other rice field weeds. It affects all growth stages of the plant with severe damage during the seedling stage. This fungi generates spores that can easily be dispersed by wind and splashing rain.

H. K. Awla et al. 1078 1. Introduction Rice (Oryza sativa L.) is among the most important crops all over the world and it is consumed as a staple as well as primary source of energy and protein. Rice blast disease, caused by the fungus Pyricularia oryzae, is among the most significant diseases affecting rice cultivation, since it is prevalent in most rice growing regions.

The ascomycete fungus Pyricularia oryzae (teleomorph: Magnaporthe oryzae), is one of the most damaging rice diseases in the world and is able to cause a yield loss of up to 30% and infect more than 50 species of grasses, including wheat, barley, oat, and millet ().Resistant rice cultivars have been used to control blast disease, but they usually lose resistance within a few years of release.
