| Abstract:
The USDA-ARS and Rutgers University (at Chatsworth, New Jersey) collectively house a significant collection of blueberry cultivated and wild germplasm. This collection of germplasm has been used to evaluate genotypes for resistance to Monilinia vaccini-corymbosii (mummy berry), Colletotrichum acutatum (anthracnose), Botryosphaeria dothidea (stem blight), Phomopsis vaccinii (twig blight), and blueberry scorch virus. These data have been compiled with similar information from other sources to produce a database that can be used for IPM recommendations, cultivar planting recommendations, and for breeding programs. Principal component analysis (PCA) can be used to compare cultivars across multiple diseases to optimize selection options. | |
