Three major soil borne pathogens namely
Phytophthora capsaici Leon causing root rot,
bacterium Ralastonia solanacearum causing bacterial
wilt and root- knot nematodes (Meloidogyne spp.) are
pervasive across the major pepper growing parts of
world mainly in the areas of repeated cultivation and
poly houses impeding production as these pathogens
are very difficult/ impossible to control. Repeated
application of chemicals is in practice among the
farmers and chemical management often leads to
environmental pollution and the presence of pesticide
residues in the fruits thus raises the concern of food
safety and reduces the export potential. Recently
grafting strategy using resistant root stock has been
proposed mainly for protected cultivation. Resistance
breeding through incorporating the resistant
genes/QTLs is the best advocated strategy to
circumvent these devastating soil-borne diseases which
aim at developing a variety/root stock having combined
and durable resistance.
Marker assisted backcross breeding is the best method
which ensures precise transfer of the resistant
genes/QTLs of interest from the donors to the recurrent
parent with accelerated recurrent parent genome
which requires thorough knowledge on the molecular
marker available for fore ground selection. This review
mainly emphasized on the molecular markers available
for breeding peppers for combined resistance to soil
borne pathogens
