Description:
Derived from the cross of D3-6-B23 (a line identified and selected during prior QTL mapping, contains a major resistance gene for barley stripe rust on chromosome 7H) with Baronesse. F1 progeny of this cross proceeded to go through three generations of MAS and five generations of selfing to create the iBISON 7H. This line was then backcrossed twice to Baronesse, and progeny underwent two generations of selfing and MAS screening for the target allele. Baronesse/D3-6-B23, F1//2*Baronesse
