(76—90 days from transplant) Cucurbita pepo. Resistant Early Bush Acorn (REBA). Developed by Cornell University. Sweet REBA Acorn continues putting energy into developing fruit long after most squash varieties have succumbed to powdery mildew. This means that the critical stage of sugar production is not debilitated by the disease late in the season. Plants are small, compact plants and produce very high yields of squash. Average 4-5 per plant and are 1.5-2 lbs, very uniform, and round. Great storage variety.
