What two squash varieties were crossed to develop the Carnival squash hybrid in 1991?

Answer

Sweet dumpling and acorn

The Carnival squash is identified as a relatively recent hybrid, having been first developed in the year 1991. This development involved the cross-pollination or crossing of two specific existing squash types: the sweet dumpling variety and the acorn variety. This hybridization process is what conferred the resulting squash with its distinctive mottled appearance and its specific flavor profile that marries sweetness with mild nuttiness.
