Interpretive Summary:

Technical Abstract: Thirty four elite breeding lines from breeding programs in the southeast region including 8 from Arkansas, 4 from North Carolina, 6 from Virginia, and 6 from University of Georgia were evaluated with Ernie and Coker 9835 as resistant and susceptible control respectively under misted conditions in Griffin-Campus, Georgia. Eleven lines showed similar level of resistance as the resistant control and 22 lines showed significantly higher severity than the resistant check, Ernie. A Virginia line, VA05W-500, from a cross of Roane / PIO 2684 // OH 552 showed the best and consistent resistance among all three replications in 36 lines. VA05W-500 showed significantly higher level of resistance than other lines including the resistant control. Many crosses have been made using Sumai3 or its derivatives as FHB resistant donors. However, FHB resistance could be enhanced significantly through combining the native resistance in soft red winter wheat germplasm. The negative yield drag associated with crosses including exotic germplasm such as Sumai3 or its derivatives could be avoided. Among the ten resistant lines, six lines, GA981621-5E34, GA98401-5E23, GA96693-4E16, AR 97124-4-3, VA05W-498, VA05W-500, and LA98090D34-4, were from crosses of native resistant germplasm, and four lines, AR 97002-2-1, ARGE97-1064-11-5, NC03-11465, NC04-27618, were from crosses of exotic resistant germplasm. Native resistant germplasm for FHB resistance should play an important role. Study on the native resistance for FHB is needed for more efficient accumulation of native resistance into local adaptive cultivars.
