Walnut Genomics Implementation Group


The Walnut Genomics Implementation Group (WGIG) is a collaborative group of researchers working in the field of walnut genomics. The goal of the group is to facilitate information exchange and to foster creativity and innovation in genetic improvement of walnut scion and rootstock. They are using molecular tools to assist in the breeding process and achieve improvement in crop quality and yield, tree structure, and resistance to pests, disease and abiotic stress. They maintain repositories of walnut genetic material to ensure the future of this promising field of research.

The group was initially formed by Chuck Leslie, and is currently chaired by David Neale. Both are affiliated with the Department of Plant Sciences, University of California at Davis. WGIG membership includes scientists with University of California at Davis, the University of Connecticut, Johns Hopkins University and the US Department of Agriculture. This group is strongly supported by the California Walnut Board.

What's New

Dec. 9, 2015
UC Davis geneticists David Neale and Charles Langley have sequenced the genome of the Chandler walnut, the leading California variety. This represents the first reference genome sequence for a nut crop. Read the announcement by the Dept. of Plant Sciences, of this achievement. Interview on local TV station.
