The peanut genome has been sequenced and analyzed as part of the International Peanut Genome Initiative, in order to accelerate breeding progress and get more productive, disease-resistant, stress-tolerant varieties to farmers. The two diploid progenitors have been sequenced and are available, along with predicted genes and descriptions. The genomes of the diploid progenitors have been used to help identify and assemble the similar chromosomes in cultivated peanut.

Cultivated peanut, Arachis hypogaea, is an allotetraploid (2n=4x=40) that contains two complete genomes, labeled the A and B genomes. A. duranensis (2n=2x=20) has likely contributed the A genome, and A. ipaensis has likely contributed the B genome.

This resource is being developed for U.S. and international peanut researchers and breeders, with support from The Peanut Foundation.
