Variation Among Winter-type Selections of Safflower1

Plants with a long-rosette period were identified in one of the local populations of safflower (Carthamus tinctorius L.) from northwestern Iran. Fifty-one lines developed from these plants showed considerable variation in winter hardiness, seed yield, oil content, oil yield per hectare, number of heads per plant, and 1,000-seed weight. The superior winterhardiness of rosette (winter) types over non-rosette (spring) types should permit fall seeding of safflower in areas where winter temperatures go as low as −15 C.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
