Resistance to five important diseases was combined in summer squash. Some of these breeding lines segregated for resistance to one or more of the five diseases and were therefore self pollinated in order to develop summer squash uniform for multiple disease resistance and other traits. Winter squash and pumpkin were bred for resistance to the same diseases. Seed was produced for virus resistant pumpkin breeding lines that performed well in a variety trial, and that seed is available for trials in the coming season.
