Interpretive Summary: Soybean cyst nematode is a threadlike microscopic worm that lives in the soil and feeds on soybean roots. Yearly losses caused by it in the United States amount to as high as $438 million. S99-3181 soybean Germplasm line was released because of its potential use in the natto market (edible) with shatter resistance, broad resistance to soybean cyst nematode and some resistance to other pests such as Southern root-knot nematode. Very few soybean germplasm lines, especially natto type, have this combination of high yield potential and broad nematode resistance. S99-3181 is expected to be used as a parent in breeding programs with a goal of producing nematode-resistant varieties to reduce soybean yield loss and the need for pesticides.
Technical Abstract: Soybean [Glycine max (L.) Merr.] germplasm line 'S99-3181' was developed at the Delta Research Center of the University of Missouri, Portageville, MO. This line has value as parent because of its good yield potential, its potential use in the natto market with shatter resistance, broad resistance to populations of soybean cyst nematode (SCN) [Heterodera glycines Ichinohe] and Southern root-knot nematode [Meloidogyne incognita (Kofoid and White)]. S99-3181 is an F5 single plant selection from the cross S93-1344 X 'Camp'. The F2 through the F5 generations were advanced by the bulk pod method. Only the smallest seed, those passing through a 3.6 mm round holed sieve, were selected and advanced. SCN resistant F6 plant rows were grown in the field at Portageville. S99-3181 was screened with individual SCN populations of HG Types 2-, 0-, and 1.3- (races 3, 5 and 14) at Portageville, Missouri and Jackson, Tennessee. S99-3181 is mid-group V maturity (RM 5.6), two days earlier in maturity than 'Hutcheson'. It was yield tested in Missouri in 10 environments from 2001-2002. Yields were similar to 'Hutcheson' on SCN non-infested loam soils and 20% more on SCN infested soils with a mean yield of 3113 kg ha versus 2938 kg ha for Hutcheson. S99-3181 has white flowers, gray pubescence and tan pods at maturity. Seeds are shiny yellow with buff hila averaging 93 mg compared to 130 mg seed for Hutcheson. Seed protein and oil content on a dry weight basis have averaged 405 g/kg and 200 g/kg, respectively versus 425 g/kg and 192 g/kg for B3. It is resistant to SCN HG types 2- (Race1), 1.2- (Race 2), 0- (Race 3), 2- (Race 5) and 1.3- (Race 14), and has moderate resistance to Southern root-knot nematode. Resistance to SCN traces to PI 437654 through Hartwig.
