Fig. 2. A principal component analysis of stearic acid versus oleic and linoleic acid contents in the F3 seed generation obtained from F2 segregant plants resulting from crosses
of high stearic sunflower with different oleic/linoleic backgrounds. Points represent the composition of individual seeds from two different lines (1 and 2). The contents of
fatty acids other than oleic, linoleic or stearic were virtually the same in all the seeds of a given line. Higher contents of stearic acid were observed in the clusters of seeds
containing higher levels of linoleic acid (cluster B), than in seeds with high levels of oleic acid (cluster A)
