Fred E Gouker    Research Geneticist (Plants) /ARSUserFiles/55045/FredGouker.jpg Grape Genetics Reseach Unit630 W. North St., Geneva, NY  14456315 787 2237 (office)Research Genetics **Overview** My research program focuses on pre-breeding, trait integration for development novel grapevine germplasm to meet the U.S. grape industry needs including rootstock, wine, table, juice, and/or raisin grapes. This work involves close collaboration with scientists in both public and private sectors to advance genetic and breeding knowledge of grapevines. My research is particularly interested in the development of a rapid-cycling breeding system to be used for the introgression of numerous identified disease resistance genes and fruit quality traits into single lines useful for further breeding and genetic improvement. **Education** **B.S.** Horticulture, Pennsylvania State University
