| 0 | PI 667595 | HA-R9 | Helianthus annuus L. | North Dakota, United States | NC7 | | | 2013 | DEVELOPED | PRE 02/28/2013 | | | | | Breeding material | HA-R9 was selected for resistance to the most predominant and the most virulent North American races of rust (caused by Puccinia helainthi Schw.), 336 and 777. Inheritance studies indicated that the rust resistance was controlled by a single, dominant gene (R11), and molecular mapping indicated that the gene R11 is closely linked to the fertility restoration gene, Rf5, present in HA-R9. Plant height of HA-R9 was 115 cm compared to 110 cm for HA 89. HA-R9 flowers 77 days after planting compared to 74 days for HA 89 in the Fargo, ND, field nursery during the summer of 2011. The fertility restoration gene Rf5 is able to restore PET1 male sterile cytoplasm, but not PET2, MAX1, GIG1, GIG2, ANN2, ANN3, or RIGX. HA-R9 is a first sunflower line in which a rust resistance gene R11 is closely linked to a male fertility restoration gene Rf5 in the coupling phase. | 1908098 | PI 667595 |
