Description

Soybean aphid resistant varieties were first released commercially in 2010. Currently all commercially available resistant varieties incorporate the Rag1 (Resistance to Aphis glycines) gene. Research from the past three years have shown: Across multiple states and years, Rag1 containing-soybeans have fewer aphids than aphid-susceptible soybeans; When aphids are present in a field, Rag1 containing-soybeans are never aphid free (Mardorf et al. 2010); Rag1 does not limit yield (Kim and Diers 2009, Mardorf et al. 2010); and Combining Rag1 and Rag2 in a soybean line provides more resistance than Rag1 or Rag2 alone (Wiarda et al. 2011).
