F5 plant was harvested from selected rows. The seed quality was evaluated visually and seed of plants with superior seed quality were scarified and planted in two-row plots in 1984. Based upon the above criteria for height, maturity, lodging resistance, and seed quality, F5-derived lines were selected for agronomic evaluation. In 1986, selected lines, along with the check cultivars 'Century', 'Williams', 'Sparks', 'Essex', and D81-9776 (a recently developed Maturity Group V impermeable seed coat line) were grown at Beltsville and Queenstown, MD in four row plots with four replications in a randomized complete block experiment to evaluate agronomic and seed quality characteristics. Md84-2751 has an indeterminate growth habit and is an early Maturity Group III genotype maturing about 1 wk earlier than Williams and Sparks (Table 1). Despite the early maturity of Md84-2751, seed quality was equal or superior to any of the check cultivars. Md84-2751 and D81-9776 had impermeable seed percentages of 95 after 24 h of soaking. Seed of Md84-2751 will be maintained by the USDA-ARS, Beltsville Agricultural Research Center-West, Beltsville, MD 20705.
