The UC Davis grape breeding program is shifting its approach to developing new
rootstock and scion cultivars. Historically, grape breeding has been largely
focused on incorporating single-gene traits related to disease resistance, and
fruit and wine quality. However, multi-gene phenotypes such as drought and heat
tolerance, fruit yield, soil adaptation, and virus tolerance, are complex and
challenging to improve, requiring a gradual increase of small-effect, beneficial
alleles. In this talk, I will discuss our efforts to integrate novel phenomics and
genomics tools to enhance the breeding of rootstocks and wine grape materials,
particularly for complex, quantitative traits that will be crucial for addressing
future climate change challenges.
