Narrative
HA-R19 is an oilseed maintainer selection from KP199. A total of 58 cultivated oilseed sunflower lines including KP199 were introduced from the Agricultural Research Council, Grain Crops Institute, Potchefstroom, South Africa in 2012. Rust screening indicated that KP199 was resistant to rust races, 336 and 777, respectively, but was segregating for rust. The resistant seedlings (S0) identified from KP199 were transplanted and self-pollinated in the greenhouse. Interestingly, thirty-two of the S1 plants from a single S1 head (14-77-2) were all resistant to rust. To confirm the homozygous nature of the S1 plants, 11 S2 families (24 plants for each family) were tested using rust race 336. All S2 families exhibited homozygous resistance with no segregation. S3 seed selected from the homozygous resistant S2 families was planted in the summer field nursery in 2017, and the harvested S4 seed bulked to form the HA-R19 germplasm originally selected from KP199. Of the 11 rust races tested, HA-R19 exhibited resistant to nine including Prust races, 336 and 777. Inheritance studies indicated that the rust resistance was controlled by a single dominant gene in HA-R19 named R18 mapped to chromosome 13 within a large gene cluster. Plant height of HA-R18 was 189 cm compared to 183 cm for the standard check hybrid 894, and flowers in 70 days after planting compared to 69 days for hybrid 894 in the field nursery at Glyndon, MN during the summer of 2017.
