Currently various pumpkin species are grown on 90,165 acres in the United States and on 219 acres of which are in Hawai’i. The primary pumpkin species marketed in Hawaii is C. maxima, but there is an opportunity to expand the market share of another species better adapted to tropical environments. This project explores genetic variability for traits related to quality and pest resistance within C. moschata. A BC1 mapping population was created between ‘Taina Dorada’ (popular culinary traits) and ‘Shima’ (locally adapted) with the F1 being backcrossed to ‘Shima’. The mapping population was grown on certified organic land using organic practices. This population showed variation for 12 different phenotypes. This population suggests that it may be possible to pyramid desirable agronomic traits with traits associated with good flavor for Hawaiian markets.
