Peanut Genomics

Translational Genomics to Reduce Pre-Harvest Aflatoxin Contamination of Peanut

Success of SNP: Genomics work one highlight of 2016
Researchers trace peanut crop back to its Bolivian roots

The goal of the project is to associate molecular variation with resistance to pre-harvest aflatoxin contamination on a genome-wide scale and to begin to utilize this information in breeding programs. To achieve the goal, both genotyping and highly replicated phenotyping of genetic resources and populations for aflatoxin contamination were pursued.

Genotyping with genome-wide SNP (single- nucleotide polymorphism) markers was enabled by peanut genome sequence information, both from cultivated tetraploid genotypes as well as diploid progenitors of the tetraploid.

Genetic populations were developed in India, Senegal and the USA. Phenotyping was done under controlled field conditions in Niger, Senegal and the US.
