The latest Roundup Ready soybean release from the University of Arkansas breeding program—UA 5715GT—offers higher yields and a more upright plant structure than its predecessor.
As with UA 5414RR, growers can save seed for planting the following year and don’t have to pay a technology fee. That’s because both varieties from soybean breeder Pengyin Chen’s program feature the first generation of the Roundup Ready technology. Monsanto’s patent on that expired in 2015.
UA 5715GT is a late maturity group V soybean that averaged 60.8 bushels per acre in the university’s soybean performance trials, according to a news release. That is nearly 3 bushels per acre better than UA 5414RR.
The new soybean has upright plant growth and is taller than its predecessor. But it is highly resistant to lodging and shattering. In addition, it is adapted to a broad range of growing conditions across Arkansas.
UA 5715GT is resistant to stem canker and frogeye leaf spot, and is moderately resistant to reniform nematodes. It is susceptible to southern root-know nematode and soybean cyst nematode (races 1, 2, 3 and 5) and moderately susceptible to sudden death syndrome.
The university’s Foundation Seed Program is selling the new variety to licensed seed dealers this year, with the initial offering of 905 bags nearly sold out. Seed should be widely available to producers in 2017.
