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.
