As with our Northern varieties (see page 14), the majority of new players in the Southern soybean market are Roundup Ready. Divided by maturity group, these pureline variety choices move from early to mid- to late maturities within each group.
Note that all the varieties listed are Roundup Ready except, of course, those boxed and labeled as conventional. A few are also STS-resistant, but they will be identified.
Some common diseases mentioned are listed by abbreviation. They are: phytophthora root rot (PRR), soybean cyst nematode (SCN), sudden death syndrome (SDS), and brown stem rot (BSR). Iron deficiency chlorosis is shortened to IDC. Note, too, that protein and oil data are based at 13% moisture.
