Project Number: 5430-21000-005-28
Project Type: Specific C/A

Start Date: Sep 09, 2004
End Date: Aug 31, 2009

Objective:
1. To make crosses between KB resistant germplasm and elite adapted breeding lines from regional wheat breeding programs. The primary focus will be to develop KB resistant hard winter wheat varieties suitable for the Great Plains, but we will also make some crosses targeting other regions. The first, second, and third target priorities of TAMU will be Texas, Colorado, and the hard spring wheat region. 2. To advance the KB resistant germplasm in the field and greenhouse and begin selection for agronomic type.

Approach:
Resistant varieties will be an important component of an integrated strategy to control KB. The use of resistant varieties is the most economical, sustainable, and long lasting means of control. There is variation in reaction in existing varieties and breeding lines, but the level of resistance is low. Since we do not have enough resistance in our adapted germplasm, we need to obtain it from exotic sources. The wheat breeding programs at USDA-ARS, KSU, OSU, and TAMU have made single and three-parent crosses with KB resistant material from India and CIMMYT. F2 and F3 generations of these populations are now being grown and we will begin to derive lines this season. Resources are needed to expand the crossing program and do initial field evaluations for agronomic type.
