ENHANCEMENT OF SCAB RESISTANT WHEAT CULTIVARS ADAPTED TO THE SOUTHEAST
Project Number: 0500-00053-003-03
Start Date: Jun 21, 2009
End Date: Jun 20, 2013
The most effective means to alleviate yield and quality losses of wheat is the development of wheat cultivars with good scab resistance. The objective of this project is to develop lines that have resistance equal to the level of Sumai 3 without the negative effect on grain yield.
Marker assisted backcrossing (MABC) of QTL from Sumai 3, Goldfield, and Ernie will be performed using high yielding and moderately resistant lines as recurrent parents. Pyramiding QTL will greatly facilitate development of cultivars that have more effective FHB resistance from active and exotic sources. Derived lines will be evaluated and validated for the presence of two major FHB resistant QTL on chromosome 3BS and 5AS among elite lines and backcross populations. Populations of BC1F2 and BC1F3 plants with AGS2000 as the current parent will be screened for markers.
