Registration of ‘TN11‐5102’ Soybean Cultivar with High Yield and High Protein Meal

Abstract

The conventional (non‐genetically modified) soybean [Glycine max (L.) Merr.] line ‘TN11‐5102’ (Reg. No. CV‐526, PI 686908) was released by University of Tennessee Agricultural Research in 2017 as a cultivar because of its high seed yield potential in Tennessee and the southern US region. The objective of its development was to provide a new cultivar combining high seed yield with high protein soymeal. The rationale is that US soybeans bred for high yield typically lead to lower protein concentration. TN11‐5102 was developed from 1 of 653 F21 single plant selections within cultivar 5601T. Progeny rows were selected on the basis of adapted maturity, lodging resistance, disease resistance, and pod density. Selections were carried forward for yield testing. TN11‐5102 is resistant to southern root knot nematode and is resistant to stem canker. It has white flowers, gray pubescence, tan pod wall, and a determinate growth habit. The plants show good resistance to lodging. Averaged over 3 yr (2014–2016) of the USDA Southern Uniform Testing Program, TN11‐5102 had 421 g kg−1 protein on a dry weight basis and 216 g kg−1 oil on a dry weight basis, and it is capable of producing 490 g kg−1 protein in the soymeal. It will serve as an excellent parent line in breeding for high yield and improved protein.
