PROJECT 1 ABSTRACTArs Agreement • March 15th, 2016
Contract Type FiledMarch 15th, 2016There is a need for new varieties that are agronomically competitive, have acceptable malting quality, improved resistance to FHB, and lower DON. The levels of resistance have improved steadily in advanced breeding lines in our program and the variety Quest with lower DON is available to growers. However, higher levels of resistance in high yielding lines are needed to reduce the overall risk of FHB to barley in the U.S. Increased need by industry for two-rowed barley will require additional breeding effort. Breeding to enhance resistance to FHB has resulted in steady progress. Many current breeding lines in our program exhibit modest levels of resistance ~50 % (or less) levels of DON compared to Robust. These lines trace back to multiple exotic sources of resistance and crossing among them should provide continued improvement in disease resistance. We have recently adopted genomic selection to select lines in early generations (F2, F3) based on predictions for DON, yield and some qual
