Diversity: The Oregon Wolfe Barley (OWB) population is a resource for understanding the importance and uses of genetic diversity in plants. The population was launched at Oregon State University and we continue to coordinate and develop the resource for genetics research and instruction. Dr. Bob Wolfe developed the parents of the population by systematically crossing recessive alleles into one parent and dominant alleles into the other parent – the dominant and recessive marker stocks. The population consists of 175 barley doubled haploid progeny derived from the cross of dominant and recessive marker stocks. This website provides access to a variety of OWB resources, ranging from data to seed.
