Rice blast caused by the filamentous ascomycete Magnaporthe grisea, is one of the most devastating diseases of cultivated rice. Blast disease is a major constraint in certain agro-ecological regions of India. Eastern India has the highest occurrence of blast, followed by North and South. This disease is also a serious problem in Gujarat, as rice is grown under irrigated and high fertilizers input conditions that are conducive to disease development. So the present investigation was taken up to identify blast resistance genes in local and improved cultivars from Gujarat along with IRRI...

Bacterial Leaf Blight caused by the bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo) limits rice yield in all major rice growing regions of the world, especially in irrigated lowland and rainfed conditions where predisposition factors favour disease development to epidemic proportions. Since bacterial pathogens are difficult to manage, development of host plant resistance is the most effective means of disease management.To combat the problem of resistance breakdown, pyramiding of resistance genes into different cultivars is being carried out. The present book deals with the gene...
