In Vitro Selection and Molecular Markers for Early Screening of Fusarium Head Blight Resistance Wheat.

The breeding of FHB resistant wheat cultivars has been a slow and frustrating process due to the multigenic nature of resistance, numerous modes of resistance, and difficulties in obtaining reliable results from screening nurseries. The result has been that only a few moderately resistant cultivars have been registered in the United States (e.g., Alsen, Ernie, Glenn, Truman) and Canada (e.g., FT Action, FT Wonder, 5602PR) over the past decade. Two methods proposed for accelerating the rate of introgression from unadapted germplasm, and ultimately increasing the frequency of potential wheat cultivars, are molecular marker assisted selection (Somers et al., 2005) and in vitro selection (Eudes et al., 2007).
