Description Cultivated groundnut or peanut (Arachis hypogaea), an allopolyploid oilseed crop with a large and complex genome,
is one of the most nutritious food. This crop is grown in more than 100 countries, and the low productivity has remained
the biggest challenge in the semiarid tropics. Recently, the groundnut research community has witnessed fast progress and
achieved several key milestones in genomics research including genome sequence assemblies of wild diploid progenitors,
wild tetraploid and both the subspecies of cultivated tetraploids, resequencing of diverse germplasm lines, genome-wide
transcriptome atlas and cost-effective high and low-density genotyping assays. These genomic resources have enabled
high-resolution trait mapping by using germplasm diversity panels and multi-parent genetic populations leading to precise
gene discovery and diagnostic marker development. Furthermore, development and deployment of diagnostic markers have
facilitated screening early generation populations as well as marker-assisted backcrossing breeding leading to development
and commercialization of some molecular breeding products in groundnut. Several new genomics applications/technologies
such as genomic selection, speed breeding, mid-density genotyping assay and genome editing are in pipeline. The integration
of these new technologies hold great promise for developing climate-smart, high yielding and more nutritious groundnut
varieties in the post-genome era.
