CucCAP scientists identify powdery mildew resistant pumpkin lines with good canning quality

Processing pumpkins grown for pie are susceptible to infection by cucurbit powdery mildew. CucCAP researchers at Cornell University sought to identify powdery mildew-resistant reeding lines with high canning quality by testing progeny derived from a cross between the susceptible industry standard and a resistant butternut squash. Two breeding lines identified with moderate and high levels of resistance were assessed for multiple canning quality traits in comparison with a store-bought commercial standard. These studies indicated that effective resistance has been bred into a commercially promising processing pumpkin background.
