In the Fredrickson/Stander population, CIM analysis detected three major QTL for FHB resistance on chromosome 2(2H) (Fig.
To determine if the trait of lateral floret size was associated with FHB severity in this population, we analyzed the two-rowed subset of the population.
Two of the major FHB resistance QTL were coincident with QTL for low DON accumulation (Fig.
Paul 2000, all the effects for the major QTL (i.e., [alpha]) located on chromosome 2(2H) were negative for FHB resistance and ranged from -4.1 to -13.4%, indicating that the Fredrickson alleles reduced FHB severity (Table 4).
In addition to the major QTL for FHB resistance identified on chromosome 2(2H), additional minor QTL were also detected explaining between five and 12.2% of the variation per locus (Table 4).
The breeding population was scored only on field grown plants for FHB severity, DON accumulation, and heading date, and therefore only the major QTL primarily detected in the field were validated.
In this study, we identified three major QTL associated with FHB resistance all residing on chromosome 2(2H).
This method identified the FHB resistance QTL associated with the heading date QTL.
In barley, late heading is usually associated with low FHB severity (Steffenson et al., 1996).
The Vrs1 locus in barley is the primary determinant of spike type (two-rowed versus six-rowed), and in general two-rowed cultivars are more resistant to FHB than six-rowed cultivars (Steffenson et al., 1996).
Validation of FHB resistance QTL is important for verifying the magnitude of the QTL and the genomic location.
Our results showed that these two QTL for FHB resistance detected in the mapping population were also identified in the breeding population.
