Narrative

HA-R18 is an oilseed maintainer selection from KP193. A total of 58 cultivated oilseed sunflower lines including KP193 introduced from the Agricultural Research Council, Grain Crops Institute, Potchefstroom, South Africa in 2012 were tested for their reaction to rust infection. The results indicated that KP193 had resistance to rust races, 336 and 777, respectively, but was segregating. The resistant seedlings (S0) selected from KP193 were transplanted and self-pollinated in the greenhouse. Of 32 plants from a single S1 head (14-76-1), four S1 plants were susceptible, while 24 S1 plants were resistant to rust and advanced to the S2 generation. Homozygous plants were selected from 24 S2 families tested using rust race 336. S3 seed selected from the homozygous resistant S2 families was planted in the summer field nursery in 2017, and the harvested S4 seed was bulked to form the germplasm HA-R18 originally selected from KP193. Of 11 rust races tested, HA-R18 exhibited resistant to eight including rust races, 336 and 777. Inheritance studies indicated that the rust resistance was controlled by a single dominant gene in HA-R18 named R17 mapped to chromosome 13 within a large gene cluster. Plant height of HA-R18 was 191 cm compared to 183 cm for the standard check hybrid 894, and flowers in 76 days after planting compared to 69 days for hybrid 894 in the field nursery at Glyndon, MN during the summer of 2017.
