A green sprouting broccoli (Brassica oleracea L. var. italica), designated ‘Hi-Test’, has been released by the Agricultural Research Service of the U.S. Department of Agriculture, and a Plant Variety Protection Certificate has been applied for it. ‘Hi-Test’ is a self-compatible, inbred cultivar that yields high-quality, uniform seed, containing high levels of the glucosinolate glucoraphanin (GR). This variety has very uniform growth characteristics, plant size, seed yield, and chemical makeup of the seed. ‘Hi-Test’ was derived from a cross of two genetically different inbred lines of green sprouting broccoli maintained in the U.S. Vegetable Laboratory (USVL) collection at Charleston, SC.
