0PI 699124'TN14-5021'Glycine max (L.) Merr. Tennessee, United StatesNLGRPNot Available2021DEVELOPEDCultivarTN14-5021 is a late-maturity group IV (relative maturity 4.9) determinate conventional soybean [Glycine max (L.) Merr.] cultivar with multiple race resistance to soybean cyst nematode (SCN). It was developed and released by the University of Tennessee soybean breeding program. Soybean cultivars with resistance to soybean cyst nematode (SCN) Race 2 are rare, yet Race 2 is becoming a predominant SCN population infecting farmers’ fields in regions of the Southeast and Mid-South. TN14-5021 also conveys resistance to stem canker, caused by Diaporthe phaseolorum (Cooke & Ellis) Sacc. var. caulivora K.L. Athow & R.M. Caldwell and strong resistance to SCN races 3 and 5. In replicated trials across 70 environments from the Mid-South to the Southeast, TN-5021 showed high yield potential and adaptation to a broad range of growing conditions. TN14-5021 has white flowers and gray pubescence. The pods have a tan pod coat, and the seeds are yellow with smooth seed coats. Across 48 environments over a four-year period, with testing locations from Kansas to Alabama, TN14-5021 averaged 406 g kg-1 and 226 g kg-1 protein and oil content, respectively. In comparison, the average protein and oil content of commercial cultivars grown in the same tests averaged 397 g kg-1 and 224 g kg-1, respectively. Its high yield coupled with elevated seed protein concentration and nematode resistance package make TN14-5021 a valuable cultivar for Tennessee and the Mid-South region.2120522PI 699124
