# CV for John Bamberg

Updated Feb 14, 2007

1\. [John Bamberg]{.underline}

USDA/ARS Geneticist, Plants (since 1989)

Project Leader, US Potato Genebank - NRSP-6 (since 1989)

Professor, Dept. Horticulture (since April 2002)

> Bamberg is Project Leader of the US Potato Genebank located on the UW
> Peninsular Agricultural Research Station near Sturgeon Bay. NRSP-6 is
> the US genebank for tuber-bearing *Solanum* species (potatoes) and is
> part of the USDA National Plant Germplasm System. It is supported by
> all SAES with off-the-top funds from USDA/CSREES, USDA/ARS and UW. The
> genebank's mission is to facilitate the improvement of potato through
> acquisition, classification, preservation, distribution, and
> evaluation of wild and cultivated potato germplasm. The Project
> provides a ready source of *Solanum* germplasm for US and foreign
> potato breeders and scientists. It coordinates evaluation of stocks by
> specialists around the US, and technology, germplasm and research
> cooperation with other potato genebanks around the world. It also has
> a strong program of on-site evaluation and characterization associated
> with *Solanum* taxonomy, genetics, physiology, genebank technology and
> other disciplines through which the exploitation of the germplasm is
> facilitated. One of the emphases of Bamberg's program has been
> collection and research on wild potatoes native to the southwest USA.
> All these physical and informational resources are cataloged and
> advertised.

2\. [Appointment]{.underline}: Genebank Administration/Service: 80%,
Research: 20%

*Research*:

EVALUATION AND GENETICS OF: Late blight, frost tolerance, hormone and
reproductive mutants, seed germination, root mass, tuber calcium,
nutritionals, apomixis, sugar-end disorder.

STATUS AND DYNAMICS OF GENETIC DIVERSITY IN THE GENEBANK:

How do our protocols affect diversity within and among genebanks? Can
diversity in the wild be predicted and how does it compare to that in
genebanks? Focus is within species.

GENEBANK TECHNOLOGY. Gather information to maximizing seed germination,
growth and reproduction, field tuberization of wild species, etc.

COLLECTING: Wild potatoes of the southwest USA and associated research
