Interpretive Summary: The interest in a mid-oleic level of sunflower oil has been greatly enhanced due to its potential use as a frying oil in the snack food industry as well as possibilities for use in the fast food industry. Benefits include low saturated fat content as well as longer life when used in deep fat frying. Little is known regarding creating a stable mid- oleic level in sunflower seed produced by the farmer. The objectives of this investigation were to study crosses between high oleic and low oleic parents as well as crosses between mid-oleic parents and their influence in creating hybrids with an acceptable fatty acid profile. Crosses between high oleic female lines and low oleic male lines produced F1 seed with oleic contents higher than 80%. One hybrid produced a mid-oleic level of F2 seed (64.4%). One cross between a low oleic female line and a high oleic male line produced both F1 and F2 seed in the mid-oleic range. The background of the female line may be extremely important with these results linked to modifier genes affecting the oleic fatty acid level. Mid-oleic female lines crossed with mid-oleic male lines produced F2 seed with acceptable mid-oleic fatty acid levels.

Technical Abstract: Previous studies have investigated the influence of the Ol and ml genes of high oleic levels of sunflower (Helianthus annuus L.) oil. Little is known regarding the influence of these germplasms on mid-oleic levels in various types of crosses. Therefore, the objectives of this investigation were to study crosses between high oleic and low oleic parents as well as crosses between mid-oleic parents and their influence in creating hybrids with an acceptable fatty acid profile. Crosses between high oleic female lines and low oleic male lines produced F1 seed with oleic contents higher than 80% in three of four crosses. One hybrid produced a mid-oleic level of F2 seed (64.4%). One cross between a low oleic female line (HA 89) and a high oleic male line produced both F1 and F2 seed in the mid-oleic range. The other two female lines tested (HA 821 and HA 372) produced F1 seed over 80% in oleic content. The background of these lines may be very important with these results linked to modifier genes affecting the oleic fatty acid level. Mid-oleic female lines crossed with mid-oleic male lines produced F2 seed with acceptable mid-oleic fatty acid levels.
