Abstract

Rice production is constrained by diseases of fungal, bacterial and viral origin. In this paper, we have discussed the various pathological symptoms in Oryza sps. Among them, Xanthomonas oryzae, Magnaporthe grisea, Rice Yellow Mottle Virus (RYMV), and brown planthopper cause high yield losses. Usage of pesticides is costly and environmentally undesirable. The genes combined with markers are close together on a same chromosome; they combine to stay together for a lot of generations. The number of disease resistance genes is identified, and they are screened by the Simple Sequence Repeats (SSR), Randomly amplified polymorphic DNA (RAPD), and Restriction Fragment Length Polymorphisms (RFLP) analysis. An attempt has been made for the development of Bph 1 linked markers using RAPD analysis.
