Finger millet a nutritionally rich underutilized crop requires
more attention of research community. One of the major
limitations of finger millet for wider agronomic acceptability
is because of its susceptibility to blast fungus Magnaporthe
grisea, which is also the causative agent of blast in rice. A
large amount of sequence data available in the public
domain has facilitated identification and isolation of novel
genes for blast resistance and other agronomically
important traits. Availability of such large genomic data
has made allele mining a viable approach for detecting
novel alleles for blast resistance in finger millet. However,
very scarce genomic information is available in finger millet,
being the major hurdle for such approaches. In the present
review, we have summarized different strategic approaches
suitable for allele mining of resistance gene analogs (RGAs)
in finger millet by utilizing the large sequence data available
for rice through comparative genomics. This paves the way
for transfer of blast alleles into high yielding, blast
susceptible and locally well adapted germplasm through
molecular breeding and genetic engineering approaches.
