Registration of soybean cultivar ‘TN15‐5007’ with high meal protein

Abstract

AbstractSoybean [Glycine max (L.) Merr.] cultivar ‘TN15‐5007’ (Reg. no. CV‐535, PI 692131) is a conventional (non‐genetically modified) cultivar released by the Tennessee Agricultural Experiment Station in 2019 on the basis of high seed yield in Tennessee, the Mid‐South, and southeastern regions of the United States. It was developed to create a high‐yielding cultivar with high meal protein. TN15‐5007 was developed from 1 of 3,500 single plants. Progeny rows were selected using breeder's phenotypic score, which includes adapted maturity, lodging resistance, disease resistance, and pod density. TN15‐5007 was a selected line and was entered in yield tests in 2015–2018. TN15‐5007 has white flowers and gray pubescence. The plants have an upright growth habit with good resistance to lodging. The pods have a tan pod coat, and the seeds are yellow. The 100‐seed weight is approximately 12.7 g, which was equal to that of ‘Ellis’ in the 2018 USDA Uniform Test. In that test, TN15‐5007 matured 2 d earlier than Ellis, the same as ‘AG 46X7’, 1 d earlier than ‘AG 4835’, and 1 d later than ‘AG 4632’, indicating that the relative maturity of TN15‐5007 is approximately 4.7, which is highly desirable for producers in Tennessee and the Mid‐South region. TN15‐5007 is resistant to the disease stem canker. It produced 436 g kg−1 protein and 213 g kg−1 oil on a dry weight basis and produced a very high 505 g kg−1 meal protein in the 2018 Southern Uniform Test.
