Registration of conventional soybean germplasm JTN-5110 with resistance to nematodes and fungal pathogens

More soybean [Glycine max (L.) Merr.] yield is lost to soybean cyst nematode (SCN; Heterodera glycines Ichinohe) in the United States each year than to any other soybean pathogen, causing estimated crop losses exceeding US$1 billion annually. Planting soybeans that resist infection by SCN and limit the reproduction of this pest is a time-tested management solution. JTN-5110 (Reg. no. GP-458, PI 678369) is a maturity group (MG) V soybean germplasm developed using molecular markers and released by the USDA-ARS in 2017 for its broad resistance to SCN as well as its resistance to reniform nematode (Rotylenchulus reniformis Linford & Oliveira), frogeye leaf spot (caused by Cercospora sojina Hara), and sudden death syndrome (caused by Fusarium virguliforme O'Donnell & T. Aoki). JTN-5110 is an F-3-derived line from the cross of experimental soybean J98-32 x 'Anand'. JTN-5110 is resistant to H. glycines (HG) types 1.2.5.7 (race 2) and 2.5.7 (race 5) as well as HG types 0, 5.7, and 7 (all corresponding to race 3). From 2010 to 2017, JTN-5110 was evaluated in 144 environments as part of 17 yield trials that included Uniform Soybean Tests and state variety trials in Arkansas and Tennessee. Seed yield of JTN-5110 was either not significantly different from or significantly higher than the trial mean in 16 of the 17 trials. JTN-5110 is an excellent choice for a MG V parent for developing soybean cultivars with durable resistance to SCN and other economically important diseases of soybean.
