Description:
HA-R11 is a BC4F3-derived BC4F4 restorer selection from the cross CONFSCLR5*5/HA-R3. CONFSCLR5 is a confection restorer line and HA-R3 (PI 650754) is an oilseed maintainer line resistant to rust (caused by Puccinia helianthi Schw.). Both were released by USDA and the North Dakota Agricultural Experiment Station in 2006 and 1985, respectively. The backcross and pedigree breeding method were used to develop HA-R11 with selection in each generation for rust resistance.
