Developing Aspergillus flavus-resistant peanut using seed coat biochemical markers

Area of inquiry: Varietal Development

Country focus: India, Niger 

Project length: Three years

Budget: $299,740

The project studies the development of the seed coat of peanut and whether increasing naturally occurring biochemicals in the seed coat can increase the resistance to A. flavus, the fungus that can produce aflatoxin.

The aim of the project is to fortify the seed coat with cell wall/antimicrobial compounds to confer pre- and post-harvest A. flavus resistance in peanut.

Specific objectives of the project are to:

1) discover seed coat biochemical(s) associated with A. flavus resistance,

2) develop biochemical Marker Assisted Selection (bMAS) pipeline for breeders in target countries, and

3) develop A. flavus resistant line(s) for field deployment in target countries.
