IA2008R and IA2022 are new soybean varieties that were developed by the Iowa State Agricultural Experiment Station and are released in Indiana. These two varieties are adapted to production in the northern half of Indiana. IA2008R is resistant to most races of a pathogen that causes Phytophthora rot, a potentially destructive disease in Indiana. This variety is also moderately resistant to brown stem rot, a disease that is becoming more prevalent in the state. IA2022 has been an exceptionally high-yielding variety in tests in Indiana. Technical Abstract: IA2008R and IA2022 are two new maturity Group II soybean varieties, each with unique traits, and adapted to production in the northern half of Indiana. IA2008R combines good yield potential with resistance to nearly every race of the pathogen causing Phytophthora rot that has been identified in Indiana, and is also moderately resistant to brown stem rot. IA2022 is a late Group II variety that has excellent yield potential, but does not have major gene resistance to Phytophthora rot. |
