RG603RR RG603RR provides a lot of flexibility for soybean producers and brings a solid mid-maturity performer to the Roughrider Genetics® brand. The yield potential of this variety puts it in the “offensive” class, but it also provides a great defensensive disease package, especially in terms of phytophthora resistance.  This variety has reasonably strong IDC tolerance and should perform very well under moderate to high IDC pressure.
