Breeding for resistance to these two pests using marker-assisted selection just got a new tool from a Texas A&M AgriLife Research study. Because genetics is the most economical strategy to minimize losses, AgriLife Research wheat geneticist Dr. Shuyu Liu began two years ago searching for breeder-friendly markers for those two insects. This step is a continuation of ongoing genetic… Read More →

New wheat streak mosaic virus resistance genetic markers developed

Advancement made in battle of major disease in the Great Plains Writer: Kay Ledbetter, 806-677-5608, skledbetter@ag.tamu.edu Contact: Dr. Shuyu Liu, 806-677-5600, SLiu@ag.tamu.edu Dr. Chor Tee Tan, 806-677-5600, chor_tee.tan@ag.tamu.edu AMARILLO – The Wsm2 gene is located on chromosome 3BS in wheat and most recently eight tightly linked flanking markers have been identified and mapped. To most, that means very little. To Texas A&M AgriLife Research geneticists and breeders, it’s the key to battling one of the most important biotic stresses affecting wheat.
