NC-Dilday is a non-GMO, high yielding, multi-environment, late maturing robust soybean cultivar suitable for production in the Southeastern United States. The cultivar produces higher levels of seed oil, lower protein content, and significantly higher crop yield than check cultivars. NC-Dilday also produces crop that is similar in seed shape and agronomic traits as check soybean cultivars. The introduction of yield enhancing genes has resulted in NC-Dilday being a high yielding Group VI cultivar derived from PI 416937.
NC-Dilday has been evaluated for five years using the NV Official Variety Test in 9 replicated environments and the USDA Southern Uniform Regional Tests in 42 replicated environments. Results from these trials showed that it averaged 2.6 bushels/acre better than early maturing check cultivar NC-Roy and averaged 3.3 bushels per acre greater than the commercial non-GMO cultivars. NC-Dilday has potential to serve as an additional high yielding, non-GMO cultivar for production and breeding in the Southeast.
