Description:
WSRC01, WSRC02, and WSRC03 (Carthamus tinctorius L.) were selected from PI 544006, PI 543995, and PI 544017, respectively. Two cycles of recurrent mass selection were completed on each of those original populations. Plots were established in the fall of 2002 for the first cycle and 2003 for the second cycle at Pullman WA (786 m elevation; 46.7247 N and 117.1355 W). Winter survival was the percentage of plants that emerged and survived to the spring count. Seed from surviving plants of PI 544006, PI 543995, and PI 544017 were harvested and bulked, and WSRC01, WSRC02, and WSRC03 produced after the second cycle of selection.
