Abstract:
Cucurbita pepo (pumpkin, squash, gourd) is an economically important species that is susceptible to the cucurbit powdery mildew fungus, Podosphaera xanthii (syn. Sphaerotheca fuliginea). 'True French', an open-pollinated cultivar of the Zucchini Group of C. pepo, was crossed with an unnamed powdery-mildew resistant straightneck-type accession, the resistance of which was apparently derived from an interspecific cross with a resistant wild species of Cucurbita, and resistant plants were selected in the F2 generation. This was followed by six cycles of backcross-pedigree selection for resistance, and resulted in the development of an accession true-breeding for resistance to powdery mildew and nearly isogenic to 'True French'. The resistant and susceptible near-isogenics were crossed and seeds of the filial and backcross generations were produced. Plants of the parental accessions and their progenies were grown together in a controlled-environment chamber, exposed to the pathogenic fungus, and scored as resistant, partially resistant, or susceptible 27-33 days after sowing. The results indicated that resistance is conferred by a single incompletely dominant gene, designated Pm-0.

Single-gene resistance to powdery mildew in zucchini squash (Cucurbita pepo)
Cucurbita pepo (pumpkin, squash, gourd) is an economically important species that is susceptible to the cucurbit powdery mildew fungus, Podosphaera xanthii (syn. Sphaerotheca fuliginea). 'True French', an open-pollinated cultivar of the Zucchini Group of C. pepo, was crossed with an unnamed powdery-mildew resistant straightneck-type accession, the resistance of which was apparently derived from an interspecific cross with a resistant wild species of Cucurbita, and resistant plants were selected in the F2 generation. This was followed by six cycles of backcross-pedigree selection for resistance, and resulted in the development of an accession true-breeding for resistance to powdery mildew and nearly isogenic to 'True French'. The resistant and susceptible near-isogenics were crossed and seeds of the filial and backcross generations were produced. Plants of the parental accessions and their progenies were grown together in a controlled-environment chamber, exposed to the pathogenic fungus, and scored as resistant, partially resistant, or susceptible 27-33 days after sowing.
