Translational genomics to reduce pre-harvest aflatoxin contamination of peanut

Duration: 01/Nov/2013 - 30/Jul/2014

Locations: Asia / India

Project contact: Dr Rajeev K Varshney (R.K.Varshney@CGIAR.ORG)

Donor: Academic institute eg university or college,University of Georgia-USA

CGIAR Research Program: Grain Legumes

The primary aim of the project will be to associate molecular variation with resistance to pre-harvest aflatoxin contamination on a genome-wide scale. This goal will be enabled by the imminent release of a peanut genome sequence and affordability of re-sequencing methods for identifying diversity in peanut germplasm and populations. Selection for genetic resistance to PAC offers the most economical route to producing a quality peanut crop. PAC results from a complex interaction of plant host (peanut), fungal pathogen Aspergillus flavus, and the environment. The advent of peanut genomics will enable genome-wide characterization of genetic differences among diverse germplasm that can contribute to reduced PAC while breeding for increased yield potential and resistance to other pests and diseases.
