Interpretive Summary: Five sunflower maintainer germplasms (HA 429 to HA 433) were developed and released by the USDA-ARS, Fargo, ND, and the North Dakota Agricultural Experiment Station, Fargo, ND. HA 429 and HA 430 were derived from the cross between cultivated sunflower lines and a wild Helianthus paradoxus sunflower. The wild Helianthus paradoxus accession was collected near Fort Stockton, TX, in a habitat with saline soil conditions. Seed derived from the cross was tested for salt tolerance for seven generations. Final selections were made under stress environments as lines and in hybrid combinations and should provide soil salinity tolerance for use in the development of hybrids, parental lines, or improved germplasms. HA 431 was derived from a cross between a USDA line and a line obtained from Argentina. HA 432 and HA 433 were derived from a cross between a USDA line and lines obtained from France. These germplasm lines provide genetic diversity for yield, agronomic characteristics, and oil concentration. Hybrids with HA 431, HA 432, and HA 433 showed lodging resistance and the stay-green characteristic over three years of testing. These lines provide increased genetic diversity to sunflower industry and public improvement programs.

Technical Abstract: Five sunflower (Helianthus annuus L.) maintainer germplasms (HA 429 to HA 433) were developed and released by the USDA-ARS, Fargo, ND, and the North Dakota Agricultural Experiment Station, Fargo, ND. HA 429 and HA 430 were derived from the cross between cultivated sunflower lines and a wild Helianthus paradoxus Heiser sunflower. The wild Helianthus paradoxus accession was collected near Fort Stockton, TX, in a habitat with saline soil conditions. Seed derived from the cross was tested for salt tolerance for seven generations using a 15 g l-1 NaCl (2.470 Sm-1) solution. Final selections were made under stress environments as lines and in hybrid combinations and should provide soil salinity tolerance for use in the development of hybrids, parental lines, or improved germplasms. HA 431 was derived from a cross between a USDA line and a line obtained from Argentina. HA 432 and HA 433 were derived from a cross between a USDA line and lines obtained from France. These germplasm lines provide genetic diversity for yield, agronomic characteristics, and oil concentration. Hybrids with HA 431, HA 432, and HA 433 showed lodging resistance and the stay-green characteristic over three years of testing. These lines provide increased genetic diversity to sunflower industry and public improvement programs.
