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

Abstract

AbstractMore 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 F3‐derived line from the cross of experimental soybean J98‐32 × ‘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.
