Interpretive Summary: The Virginia State University, Agricultural Research Station and the U.S. Department of Agriculture, Agricultural Research Service developed and released a new vegetable soybean cultivar named Owens on May 8, 2003. This report describes the breading and characteristics of the new vegetable soybean cultivar. Vegetable soybean can be harvested at either of two stages: 1) green pod or 2) mature seed. When harvested at the green pod stage, the pods may be lightly cooked in salted, boiling water and the seeds then pressed from the pods with the fingers and ingested directly, or the beans may be shelled from the pod and added to stews, mixed vegetables, soups, casseroles, or stir-fry dishes. When harvested at the mature seed stage, seeds can be used for several soyfood products such as tofu, soymilk or roasted nuts. Vegetable soybeans offer the potential for expanding domestic and international soybean markets. Vegetable soybeans provide farmers, particularly organic vegetable producers, with another crop option to supplement farm income. Vegetable soybeans fit well into existing crop rotation patterns, provide a cash summer crop, and enable farmers to amend soils with green crop residue. Owens seeds have a high concentration of protein, oleic acid and sucrose. Oleic acid confers health benefits in reducing serum cholesterol levels. Owens provides growers with a vegetable soybean with large seed size. Owens is later in maturity than most vegetable soybean cultivars and therefore extends the season during which soybeans can be harvested.

Technical Abstract: The Virginia State University, Agricultural Research Station and the U.S. Department of Agriculture, Agricultural Research Service developed and released the vegetable soybean cultivar Owens. Owens is an F5 derived line from the cross PI417288 x T145. PI417288 is a vegetable-type soybean, MG V from Japan with moderate resistance to Mexican bean beetle defoliation. T145 is a glabrous mutant line found in Illini and maintained by the USDA at Urbana, IL. Owens has white flowers, tawny pubescence, and brown pod walls. Seeds have brown seed coats and brown hila. Plants have determinate growth habit. Owens is a maturity group V cultivar. At Tifton GA, the green pod yield for Owens was 6639 kg ha-1 compared to 4950 kg ha-1 for Moon Cake. At State College, PA Owens’ two-year average shelled green bean yield was 5930 kg/ha as compared to Moon Cake’s yield of 7406 kg/ha. At Virginia State University, the three-year average mature seed yield of Owens was 2209 kg ha-1 compared to 2513 kg ha-1 for Hutcheson. Mature seed composition of Owens averaged 441 g kg-1 protein and 181 g kg-1oil, with 24.2 % of the oil as oleic acid. The three-year dry seed weight for Owens in Virginia was 20 g per 100 seeds while Hutcheson seeds weighed 18 g 100 seeds. The three-year average seed shattering score for Owens was 3.5 compared to 1.0 for Hutcheson with 1 = no shattering and 5 = severe shattering. The three-year average plant height of Owens was 55 cm compared with 71 cm for Hutcheson. In tests at Jackson, TN, Owens was susceptible to race 14 of the soybean cyst nematode. In tests at West Lafayette, IN Owens was resistant to race 1 and 2, but susceptible to races 25 and 33 of the phytophthora root rot pathogen. In southern Indiana field tests, Owens was moderately resistant to sudden death syndrome and frogeye leaf spot.
