Abstract
The glyphosate-tolerant soybean [Glycine max (L.) Merr.] line ‘TN16-520R1’ (Reg. no. CV-560, PI 703273) was released as a high-yielding cultivar by University of Tennessee Agricultural Research in 2018. TN16-520R1 is a BC4F2 cultivar derived from the recurrent parent ‘Ellis’, with drought tolerance and a maturity group (MG) of V-early. It has white flowers, gray pubescence, tan podwall, and a determinate growth habit. The seed has buff hila, is yellow with smooth seed coat, and contains 40% protein and 22% oil on a dry weight basis. TN16-520R1 has good resistance to lodging and good seed quality (1.8 and 1.6, respectively, on 1–5 scale), and a seed size of 11.8 g per 100 seed. Like Ellis, TN16-520R1 has performed competitively throughout much of the mid-South United States over several years, with testing occurring over a 6-year period in 100 environments. Further, TN16-520R1 is remarkably like the recurrent parent Ellis for yield, maturity, lodging, height, protein, and oil. Also, like Ellis, TN16-520R1 is resistant to stem canker [caused by Diaporthe phaseolorum (Cooke & Ellis) Sacc. var. caulivora K.L. Athow & R.M. Caldwell] and southern root-knot nematode [Meloidogyne incognita (Kofoid and White) Chitwood] and has field tolerance to frogeye leafspot [caused by Cercospora sojina (Hara)]. This combination of beneficial traits and broad adaptability make TN16-520R1 an excellent choice as a soybean cultivar for producers or a crossing parent for breeders.
期刊介绍:
The Journal of Plant Registrations is an official publication of the Crop Science Society of America and the premier international venue for plant breeders, geneticists, and genome biologists to publish research describing new and novel plant cultivars, germplasms, parental lines, genetic stocks, and genomic mapping populations. In addition to biomedical, nutritional, and agricultural scientists, the intended audience includes policy makers, humanitarian organizations, and all facets of food, feed, fiber, bioenergy, and shelter industries. The scope of articles includes (1) cultivar, germplasm, parental line, genetic stock, and mapping population registration manuscripts, (2) short manuscripts characterizing accessions held within Plant Germplasm Collection Systems, and (3) descriptions of plant genetic materials that have made a major impact on agricultural security. Registration of plant genetic resources, item (1) above, requires deposit of plant genetic material into the USDA ARS National Plant Germplasm System prior to publication.
