Interpretive Summary: Worldwide soybean yields are primarily limited by a microscopic root worm called soybean cyst nematode (SCN). Annual yield losses caused by SCN alone to soybean growers in US Resistant cultivars have been an effective means of nematode control but also caused major shifts in nematode populations. Over time, these variable SCN populations have adapted to resistant cultivars and rendering them susceptible and continue to cause yield losses to growers. Soybean breeding for developing cultivars with durable resistance remains a constant challenge to soybean industry. We have developed and released a new soybean JTN-5203 in 2012 in cooperation with the University of Tennessee. This soybean has broad resistance to SCN populations (Race 2,5,14 and moderately resistant to Race3) as well as reniform nematodes, and several fungal diseases, combined with very high yield potential up to 56 bushels/acre. JTN-5203 was developed from a cross between two parental lines, Caviness and Anand. JTN-5203 has white flowers, gray pubescence, and a determinate growth habit and primarily adapted to Midsouth area. Seeds are yellow in color. Among major fungal pathogens, JTN-5203 is resistant to Frogeye leaf spot, Sudden death Syndrome, and Stem canker. JTN-5203 is an excellent conventional bean for producers in the Midsouth and Southeast regions of USA.

Technical Abstract: JTN-5203 soybean [Glycine max (L.) Merr.] (Reg. No. XX-XXX, PI 664903) was developed and released by USDA-ARS in collaboration with the University of Tennessee in 2012 for its broad resistance to soybean cyst nematode (SCN; Heterodera glycines Ichinohe), as well as reniform nematode (Rotylenchulus reniformis) and fungal diseases, combined with its high yield potential. JTN-5203 is an F6-derived line from the cross Caviness × Anand. The F1 plants were advanced to the F5 generation using single pod descent method in Costa Rica during 1997-99. Single F6 plants were harvested to produce progeny plant rows which were visually selected at Knoxville, TN for disease resistance and agronomic appeal. Selected plant rows and later generations were advanced and evaluated using bulk-row method. Selected plants were evaluated in the greenhouse bioassays for SCN resistance, and were confirmed using marker assisted selection. JTN-5203 was entered in the USDA Uniform Soybean Tests, Southern Region Preliminary V and Uniform V Tests for multiple years from 2005 to present. Further evaluations were conducted for Frog eye leaf spot (Cercospora sojina), reniform nematode, sudden death syndrome (SDS; caused by Fusarium solani f. sp. glycines), and stem canker (Diaporthe phaseolorum var. meridionalis). JTN-5203 was found resistant to these multiple pathogens. JTN-5203 will serve as an excellent parent material in breeding programs for providing durable resistance to multiple nematode populations, several fungal pathogens, while maintaining high yield potential for cultivar improvement. Germplasm line JTN-5203 could also serve as an excellent conventional soybean cultivar for producers in the Mid-South and Southeast regions of USA.
