Korea Releases Tasty New Pest-Proof Rice

December 23, 2010

The continuing research collaboration between Korea Rural Development Authority and the International Rice Research Institute (IRRI) has released another product – the Anmi japonica rice. Anmi is a high quality medium grain rice typically grown in temperate countries. It is highly resistant to a destructive rice pest,  the brown planthopper (BPH), and also to blast, bacterial blight, and rice stripe virus.

The BPH resistance of the variety was developed through genetic research led by IRRI plant breeder Dr. Kshirod Jena. He said, "In 2004, we had a significant breakthrough when we were able to locate the gene Bph18 for BPH resistance. We were then able to add this gene to a BPH-susceptible elite japonica rice variety successfully employing the modern rice-breeding technique called marker-assisted breeding for the first time ever in japonica rice." 

Anmi, besides containing multiple resistance to pests is also high yielding, at more than 5.8 tons per hectare, 11% more yield than the best japonica check variety in Korea, Hwaseongbyeo.
