Interpretive Summary: Producing NuSun sunflower hybrids with a mid-oleic (55-75%) level could be feasible by utilizing a mid-oleic female crossed with a mid-oleic male parent. Stability of oil with the oleic level within this level is in demand for frying purposes and this oil is a high priority of processors purchasing NuSun sunflower seed. The objective of this study was to observe oleic levels of seeds produced on hybrid plants created by crossing a mid-oleic female and a mid-oleic male parent. The oleic level was also determined from crosses of mid-oleic female parents and high linoleic male parents. The oleic level of the parents were also tested over a 1995 to 1999 period. Even utilizing the single-seed descent breeding methodology over 5 generations, the oleic concentration of both the female and male lines varied considerably. However the average of all plants of each line was mid-oleic. Hybrids produced by crossing the mid- oleic female lines with the mid-oleic male lines produced hybrid seed that averaged mid-oleic. However, the range of oleic concentration produced by some hybrids was quite wide. It appears that the restorer lines tested in this experiment possess different modifier genes affecting oleic concentration.

Technical Abstract: Producing NuSun sunflower (Helianthus annuus L.) hybrids with a mid-oleic (55-75%) level could be feasible by utilizing a mid-oleic female crossed with a mid-oleic male parent. Stability of oil with the oleic level within the 55-75% range is critical for frying oil quality characteristics and is a high priority of processors purchasing NuSun sunflower seed. The objective of this study was to observe oleic levels of seeds produced on hybrid plants created by crossing a mid-oleic female and a mid-oleic male parent. The oleic level was also determined from crosses of mid-oleic female parents and high linoleic male parents. The oleic level of the parents were also tested over a 1995 to 1999 period. Even utilizing the single-seed descent breeding methodology over 5 generations, the oleic concentration of both the female and male lines varied considerably. However the average of all plants of each line was mid-oleic. Hybrids produced by crossing the mid-oleic female lines with the mid-oleic male lines produced hybrid seed that averaged mid-oleic. However, the range of oleic concentration produced by some hybrids was quite wide. It appears that the restorer lines tested in this experiment possess different modifier genes affecting oleic concentration.
