Description Full yield potential of any crop cannot be harnessed completely due to several
challenges such as biotic and abiotic, faced by the crops at various growth stages.
Biotic stresses caused by viruses, bacteria, fungi, pathogen, parasites, pests and
weeds pose major threat to sustainable productivity by reducing yield from 30% in
general to complete yield loss in some severe epidemic cases. Crop protection
measures for safe-guarding crops such as use of synthetic pesticides, weedicides, etc.
have largely beenlielpFul in curtailing the losses, however, their haphazard use have
caused adverse environmental and health hazards. Genetic alternatives such as
introgression/pyramiding of genes/auantitative trait loci associated with resistance
to target pest and diseases, on the otner hand, is much ecological and eco-friendly
approach. Although, there are several biotic stress agents for any crop, however, only
a few pests or diseases cause major yield loss. It is beyond the scope of this review to
cover all the pests and diseases affecting all the crops, thereby, focus has been given
on major pests and diseases of representative crops such as rice (cereal), chickpea
(legume) and tomato (vegetable). Special emphasis has been given on the current
status and future prospects of deploying modern breeding approaches for developing
improved cultivars with high resilience to major biotic stresses in order to achieve
maximum genetic yield potential in all the crops.
