Merr.] line 'DT98-7553' with moderate resistance to charcoal rot disease caused by Macrophomina phaseolina (Tassi) Goidanich, was developed and released by the U.S. Department of Agriculture-Agricultural Research Service, Stoneville, Mississippi. Using colony-forming units, colony forming units index, root and stem severity scores and other rating methods, DT98-7553 was shown to have significantly lower levels of M. phaseolina infection than susceptible checks in field trials in Stoneville, MS and Jackson, TN. DT98-7553 was rated as resistant to southern stem canker, caused by Diaporthe phaseolorum in Stoneville, MS based on two years of screening using toothpicks infested with D. phaseolorum. In replicated field test tests conducted by the USDA-ARS in 7 trials over 2001 and 2002 at Stoneville, MS DT98-7553 produced a seed yield of 3222 kilograms/hectare (kg/ha). This was significantly greater than the check cultivar Hutcheson (2964 kg/ha), which was a parent to DT98-7553. DT98-7553 was 5 days later in maturity than Hutcheson. DT98-7553 had a height of 69 cm which was the same as Hutcheson. Mean lodging score was 2 for both DT98-7553 and Hutcheson. No protein or oil data is available from these trials. DT98-7553 has white flowers, tawny pubescence, segregating brown/tan pod wall, and a determinate growth habit. Seeds are yellow with brown hila. NOTE: The Notice of Release states that the hilum is black, but it is really brown. | 1931804 | PI 675995 |

DT99-16864 was susceptible to the root-knot nematodes Meloidogyne incognita (Kofoid and White) Chitwood and Meloidogyne arenaria (Neal) Chitwood. Based on two years of data in the Uniform Tests, DT99-16864 is resistant to southern stem canker [caused by Diaporthe. phaseolorum} and Soybean mosaic virus (strain G1). DT99-16864 produced an average seed yield of 2909 kilograms/hectare (kg/ha) in the Uniform Tests (2003-2004). Over the same 2-year period in the Uniform Tests, seed of DT99-16864 averaged 41.0 percent protein, 18.8 percent oil, and 14.2 grams/100 seed. DT99-16864 had a plant lodging score of 2.2 (where 1 = all plants upright and 5 = all plants prostrate), seed quality score of 1.8 (where 1 = excellent and 5 = poor) and height of 73 cm. DT99-16864 belongs to maturity group 5 with relative maturity 7 d after the cultivar 5002T.

In replicated field tests conducted by the USDA-ARS in 13 tests over 2002, 2003 and 2004 in Mississippi, DT99-17554 produced a seed yield of 3485 (kg/ha). This was not significantly different than the check cultivars Hutcheson (3422 kg/ha), Freedom (3427 kg/ha), or P9594 (3543 kg/ha). DT99-17554 is a relative maturity group V and was 1 day later in maturity than Hutcheson. DT99-17554 had a height of 72 cm. DT99-17554 had a mean lodging score of 2 (where 1 = all plants upright and 5 = all plants prostrate). No protein or oil data are available from these trials.

Merr. | Mississippi, United States | SOY |  | | 2006 | DEVELOPED | 02/01/2006 | | | | | Breeding material | DT97-4290 has an indeterminate growth habit, purple flowers, tawny pubescence, and tan pod walls. Seed are shiny yellow with black hila. DT97-4290 is classified as Maturity Group IV (relative maturity 4.8), and matures about 2 d earlier than `Manokin?. In three years of USDA Uniform tests, plant height of DT97-4290 averaged 91 cm compared to 75 cm for that of Manokin. The plant lodging score of 2.0 (where 1 all plants upright and 5 all plants prostrate) and seed quality score of 2.2 (where 1 excellent and 5 poor) of DT97-4290 were similar to those of Manokin. Seed weight of DT97-4290 averaged 144 mg/seed compared to 122 mg/seed for Manokin. Seed of DT97-4290 averaged 415 g/kg protein (zero moisture basis) and 197 g/kg oil (zero moisture basis), which is 11 g/kg more protein and 9 g/kg less oil than that of Manokin. DT97-4290 is moderately resistant to charcoal rot based on field evaluations from 2002 to 2004 in artificially infested sandy loam soil at Stoneville, MS. The severity of internal discoloration for stem and root was measured on a scale of 1-5 (where 1 = resistant, >1 to 2 = moderately resistant, >2 to <3 = moderately susceptible, and 3 to 5 = susceptible). The severity value for DT97-4290 over the three year study averaged 1.6, whereas susceptible check Manokin averaged 3.6. DT97-4290 is the first soybean germplasm line to be released specifically for its resistance to charcoal rot. It is a valuable source of resistance for soybean breeders and producers in areas experiencing yield losses due to charcoal rot. DT97-4290 is resistant to southern stem canker (similar to resistant check cultivar Manokin), soybean mosaic virus, and races 2, 4, and 10 of phytophthora rot [caused by Phytophthora sojae (M.J.Kaufmann and J.W. Gerdemann)]. DT97-4290 is also moderately resistant to frogeye leaf spot [caused by Cersospora sojina Hara]. | 1694792 | PI 642055 |
