Montana Researchers Develop Spring wheat Cultivars Resistant to Orange Wheat Blossom Midge
August 6, 2010| |
Agronomists from the Montana State University (MSU) Research Centers (RC), together with MSU scientists, are currently working on spring wheat cultivars with resistance to orange wheat blossom midge (OWBM). The 2006 outbreak of OWBM costs wheat producers in Flathead County more than $1.5 million. They were able to harvest only two to three bushels per acre, instead of the expected 80 bushels per acre.
"OWBM is a problem in spring and winter wheat around the world, not just in Flathead County. An OWBM resistant cultivar will benefit many growers," said Bob Stougaard, agronomist from Northwestern RC who discovered that some spring wheat varieties were very susceptible to the pest, while others were less attractive to the adult female midges.
MSU molecular geneticist Jamie Sherman has identified molecular markers to screen and select genetic material carrying the gene for resistance to OWBM.
