EVALUATION OF SAFFLOWER LINES WITH LOW IODINE NUMBERS^ L. N. Leininger LNES of safflower, Carthamus tinctorius L., whose seed contain oil of low iodine number, were reported in Australia as early as 1949. These were introduced into the United States and analyzed by the Northern Utilization Research and Development Division at Peoria, Illinois. This analysis is compared with a commercial safflower variety (N-10) and olive oil (Table 1). Oil of the two introduced safflower lines closely resemble olive oil, while oil of N-10 variety is quite different. Variation in iodine number results from extreme differences in oleic and linoleic fatty acid constituents with little change in saturated fatty acids (primarily palmitic and stearic). The entire collection of safflower introductions was evaluated for iodine number in 1958 and 1959 and as a result, 9 additional lines whose oils showed iodine numbers of less than 120 were selected. Earlier work had resulted in six similar lines. This gave a total of 17 lines of varying ancestry but with iodine numbers varying from 87 to 119. No selection was practiced within lines carrying a plant
