PGRU Vegetable Crops: A Reservoir of Genetic Diversity

Monday, January 21, 2013 at 12:20pm to 1:10pm

Barton Hall NYSAES, A134 630 West North Street Geneva, New York

Seminar originates in A134 Barton Hall, Geneva. Available via Polycom in 404 Plant Science.
Part of the Department of Horticulture seminar series

At the PGRU gene bank more than 12,500 accessions (populations) of vegetable crop species and their wild relatives are conserved as seed. Our mission is to acquire, maintain, characterize, and distribute these genetic resources. My research focusses on molecular and population genetic characterization of the collections in order to estimate diversity and how it is partitioned. In addition, quantification of health beneficial traits has become of high priority. Genetic and phenotypic characterization of the collections can enhance their value by helping end users decide which accessions to incorporate into breeding programs. After introducing the National Plant Germplasm System (NPGS) and PGRU, I will present recent research results using examples from tomato. Future planned projects (in tomato, wild tomato, tomatillo, winter squash, onion) and outreach activities will also be briefly described.
