The lines were derived from two cycles of mass selection. Plants of each original accession were fall planted at Pullman WA (786 m; 46.7247 N and 117.1355 W) and seed of surviving plants bulked for each cycle. Selection WSRC01 was derived from PI 544006 from Runan, in Zhumadian County, Henan, province, China, and WSRC02 was derived for PI 543995 originating from Jingxian County, Hebei Province, China. Original populations of WSRC01 and WSRC02 were observed to have a long rosette period under greenhouse conditions, typical of winter type safflower. The selection WSRC03 was derived from PI 544017 from Ruicheng County, Shanxi Province, China, and was reported to have winter hardiness by Professor Li Dajue working at the Beijing Botanical Garden. Seed oil for all the original populations is low, averaging 22%. All are linoleic fatty acid types with average values of 80% linoleic and 13.6% oleic fatty acids. All three original accessions had superior winter survival compared to spring type checks and other winter types. Spring type checks reportedly varying in cold tolerance did not survive winter conditions in eastern Washington locations. Variation within the original accessions was sufficient for successful mass selection. Selection increased winter survival and average of 5.2% for WSRC01, 25.8% for WSRC02 and 69.5% for WSRC03. Average winter survival for WCRC01 was 92%, for WCRC02 84% and for WCRC03 67%. All lines are facultative, in the sense that seed is produced when either spring or fall planted. Anthesis and maturity for fall planted lines occurred from 14 to 16 days earlier than when spring planted. In Eastern Washington, maturity of fall planted material was late July to early August at lower elevation (206 m) and 14 to 18 days later at higher elevations (786 m). All three lines are erect with branching on the upper two-thirds of the plant. Plant height of lines when winter planted averaged 86 cm, 9 cm more than when spring planted. Flower color when florets are dry is red and capitula spine density is light. | 1745446 | PI 651878 |
