Abstract

The reactions of 50 cultivars and breeding lines of muskmelon (Cucumis melo L.) to inoculation with a pathogenic strain of Myrothecium roridum Tode ex Fries were evaluated using detached leaf tissues from greenhouse plants and immature fruits from field-grown plants. Leaf susceptibility was characterized by chlorosis, necrosis, and extensive fungus sporulation, whereas fruit susceptibility was evidenced by host tissue decay and fungus sporulation. Differences in reactions among muskmelon cultigens using detached leaves were consistent among tests and correlated well with susceptibility of young, immature fruits. Tolerance appeared to decrease with increasing physiological age of the immature fruits. ‘Hales Best’ exhibited the greatest tolerance, whereas ‘Summet’ was very susceptible.
