Interpretive Summary: Soybean yields worldwide are limited by the soybean cyst nematode (SCN), a microscopic size roundworm attaching to the roots of plants. SCN feeds on the plant nutrients. Annual yield losses in the U.S. exceed one billion dollars. Resistant cultivars have been the most effective means of controlling the nematodes. A conventional soybean (non-GMO) line TN09-008 was developed and released by University of Tennessee Agricultural Research in 2017 as a cultivar in cooperation with USDA-ARS. The release is based on its high seed yield potential and resistance to multiple pathogens in Tennessee and the Southern region. Soybean TN09-008 was developed from the cross ‘Fowler’ x ‘Anand’. Both parents are resistant to multiple nematode populations additionally ‘Fowler’ soybean is high yielding. In 2013 tests TN09-008 produced 4338 Kg/ha compared to the test mean of 4338 Kg/ha and the check (AG5332) mean of 4486 Kg/ha. TN09-008 is highly resistant to SCN populations, race 2, 3, and 5. It is also resistant to stem canker, sudden death syndrome and frogeye leaf spot. With the renewed interest in high yielding conventional soybeans having resistance to multiple pathogens, growers can be highly benefitted by its adoption.

Technical Abstract: The conventional soybean line TN09-008 (Reg. No. CV- , PI ) was released by University of Tennessee Agricultural Research in 2017 as a cultivar, based on high seed yield potential in Tennessee and the southern region. Soybean cultivar TN09-008 is resistant to HG types 1.2.5.7, 5.7, and 2.5.7 (races 2, 3, and 5, respectively) of soybean cyst nematode (SCN, Heterodera glycines Ichinohe), resistant to stem canker Diaporthe phaseolorum var. meridionalis, and shows field tolerance to sudden death syndrome (SDS, caused by Fusarium solani f. sp. glycines), and frogeye leaf spot (Cercospora sojina K. Hara). TN09-008 is a maturity group V line with relative maturity of approximately 5.3. It will serve as an excellent parent line in breeding for broad resistance to SCN and several other important pathogens of soybean.
