What is VitisGen?

VitisGen is a large, multi-disciplinary, collaborative project focused on decreasing the time, effort and cost involved in developing the next generation of grapes. Vitisgen incorporates cutting edge genomics technology and socioeconomic research into the traditional grape breeding and evaluation process, which will speed up the ability to identify important genes related consumer-valued traits like disease resistance, low temperature tolerance and enhanced fruit quality. Identifying these genes will help grape breeding programs from around the world to more rapidly develop new grape varieties that will appeal to a wide range of consumers, while also addressing grower and producer needs. Additionally, the scientific resources developed during the project will allow scientists and breeders to address other issues and needs that have regional significance, like salinity or drought tolerance.

Vitisgen represents a new model of scientific collaboration. The integration of the needs of multiple interests—breeders, growers, fruit processors and consumers—into a single outcome will result in novel grape varieties that are beneficial to producers, processors and consumers.

Industry Voices in Support of VitisGen

The Value of Powdery Mildew Resistance in Grapes:
Evidence from California

Members of VitisGen’s Trait Economics Team recently published an article on the value of incorporating resistance to powdery mildew into new grape varieties. Incorporating PM resistance into varieties used for raisin production, for example, could save over $36 million per year in vineyard costs for raisin growers alone. This article was originally published in the May/June 2014 issue of the Agricultural and Resource Economics Update published by UC-Davis.

VitisGen Voice newsletter, Issue 3 now available!

The new issue of the VitisGen Voice newsletter is available for download. This issue focuses on the work of the Low Temperature Response Team, which is working to better understand the genetic factors that influence how grapevines survive extreme winter temperatures, and the timing of when vines emerge from dormancy, which can determine whether they suffer early spring frosts or not.
