Economic importance:

  • Gene sources: tertiary genetic relative of maxima pumpkin/squash   (xerophytic species as Cucurbita cordata have not produce hybrids with cultivated Cucurbita fide Evolution 18:555. 1964)
  • Gene sources: tertiary genetic relative of moschata pumpkin/squash   (based on sterile hybrids in crosses with Cucurbita moschata fide Syst Ecogeogr Stud 9:27. 1995)
  • Gene sources: tertiary genetic relative of pepo pumpkin/squash   (based on failed crosses with Cucurbita pepo fide Evolution 18:555. 1964)
  • Gene sources: tertiary genetic relative of cushaw   (based on failed crosses with Cucurbita argyrosperma fide Evolution 18:555. 1964)
  • Gene sources: tertiary genetic relative of fig-leaf gourd   (xerophytic species as Cucurbita cordata failed in tests for crossability with a few cultivated Cucurbita fide Evolution 18:555. 1995)
