“…Hybridizations were made with two low‐16:0 lines and one low‐18:3 line developed by the USDA Soybean Genetics program at Raleigh, NC, with the intent to backcross the desirable fatty acid traits into higher‐yielding and improved agronomic genotypes. Adapted cultivars used as recurrent parents were Hagood (MG VII) (Shipe et al, 1992) and Maxcy (MG VIII) (Shipe et al, 1995). A cross of Dillon (MG VI) (Shipe et al, 1997) by a low 18:3 line was also made.…”

A primary focus for soybean [Glycine max (L.) Merr.] breeders recently has been the development of cultivars with improved oil qualities such as reduced palmitic acid (16:0) and linolenic acid (18:3). A backcross breeding program was used to develop five low 16:0, two low 16:0 + 18:3, and one low 18:3 modified fatty acid breeding lines (MFALs). Research objectives were (i) to determine planting date effects on fatty acid content in the eight MFALs and (ii) to compare the MFALs to parental cultivars for seed composition and agronomic traits. The eight MFALs and four control cultivars were evaluated at two planting dates at Clemson, SC, in 2001, 2003, and 2004. Planting dates were chosen to simulate full season and double crop planting dates for South Carolina soybean production. Agronomic traits including seed yield, plant height, lodging, maturity date, seed size, and seed quality were measured, and seeds were analyzed for protein, oil, and fatty acid levels. Planting date had a significant effect on all agronomic variables, as well as on protein, oil, and palmitic and linolenic acid. There was a decrease in palmitic acid at the late planting date, while the early planting date resulted in a decrease in linolenic acid levels. The effect of genotype was significant for all agronomic and seed composition variables measured when averaged across planting dates. It appears that planting date may be manipulated to reduce palmitic or linolenic acid of MFALs, although the extent of the reduction varies with genotype.

“…he intermediate yield trial was grown at two locations, in Florence, SC, and Blackville, SC. here was a total of 30 breeding lines and 3 commercial checks: 'Santee' (Shipe et al, 2003), 'Dillon' (Shipe et al, 1997), and 'Motte' (Shipe et al, 2000). Agustina yielded an average of 3114 kg ha -1 , which was 121 kg ha -1 higher than the test mean but 249 kg ha -1 less than the average yield of all three checks combined.…”

‘Agustina’ soybean [Glycine max (L.) Merr.] cultivar (Reg. No. CV‐524, PI 679941) was developed by the Clemson Pee Dee Research and Extension Center in Florence, SC. It was released in 2016 because of its ability to delay flowering under short‐day conditions and produce high yields, which is due in part to the long juvenile (LJ) trait. The LJ trait extends the period between germination and flowering under short‐day growing conditions. Thus, the latitude in which the cultivar is grown can have a large impact on maturity. When grown in Florence, SC, Agustina was tested as a maturity group (MG) VIII, high‐yielding, conventional (non‐genetically modified) cultivar. When tested ∼12° further south in Tampico, Mexico, Agustina was classified as a MG IX cultivar. In Tampico, (27° N), the furthest south it was tested, Agustina was the highest‐yielding line in the test, outyielding the highest‐yielding check by 222 kg ha−1. Agustina traces to a single plant selection in the F5 generation in 2010 from a cross between SC98‐1850 and ‘Manokin.’ Agustina exhibits white flowers, tawny pubescence, and an imperfect black hilum color. It has excellent resistance to soybean cyst nematode HG type 2.5.7 (race 1) and HG type 0 (race 3) and moderate resistance to HG type 2.5.7(race 5). Agustina is a highly versatile cultivar that performs well across multiple environments.
