`Butterbowl' (NE-RBN-4) is a novel, small-sized (0.8 to 1.36 kg), flavorful (sweet), early maturing (90–95 days), near-oblate butternut type winter squash variety (Cucurbita moschata Duch. Ex Poir). No Butternut squash variety is similar in shape to `Butterbowl'. `Butterbowl' (S6) was derived from selfing a near-oblate open-pollinated S4 line derived from a cross of two true breeding crookneck lines (allelic test) NE-BNCR-67-1-7 (mutant out of `Butternut 23') X golden Cushaw (Agway Co.). Total fruit yield and fruit weight of `Butterbowl' were nearly similar to Butternut `Ponca'. The total fruit weight of'Waltham' was greater than `Butterbowl' in two out of four trials. The vining habit of `Butterbowl' (1.7 to 2.0 m) is more compact than `Waltham' or `Ponca'. `Butterbowl' is suitable for small gardens with limited space due to its compact plant habit. No crookneck fruit developed in `Butterbowl' in all tests. `Butterbowl' is resistant to bacterial spot, black fruit rot, and vine borer while it is moderately susceptible to powdery mildew. `Butterbowl' fruit should be used for consumption up to 45 to 55 days after harvest because slight fruit shriveling occurs at that time due to moisture loss. The fruit cooks uniformally in a microwave oven due to its more uniform flesh thickness.
