NC-Dunphy is a non-GMO, high yielding, multi-environment, early maturing robust soybean cultivar that is suitable for production in the Southeastern United States. The cultivar has larger seeds, shorter plant stature, greater lodging resistance, and higher seed oil content than check cultivars. NC-Dunphy also produces crop that is similar in seed shape and agronomic traits to check soybean cultivars. The introduction of yield enhancing genes has resulted in NC-Dunphy being perhaps the highest yielding Group VI cultivar derived from PI 416937.
NC-Dunphy has been evaluated in the USDA Southern Uniform Regional Tests and it showed significantly higher yield than any other released check cultivars over 27 replicated environments. Results from these trials showed that it averaged 6.8 bushels/acre higher than early maturing check cultivar Dillion and averaged 4.5 bushels/acre greater than the commercial NC-Roy cultivars. NC-Dunphy has the potential to serve as an additional high yielding, non-GMO cultivar for production and breeding in the Southeast.
