TAMRUN OL07 PEANUT is a release of the high oleic (hi O/L) runner type peanuts from Texas AgriLife Research. The objective of releasing this variety was to provide producers with a peanut that has more resistance to tomato spotted wilt virus and Sclerotinia minor Jaggar than current varieties without sacrificing yield potential and affecting quality.
Plants of Tamrun OL07 are larger in general than Tamrun OL01, yet similar to Tamrun OL01 in that they are profusely branched near the base of the plant. Yields and grades vary across the peanut production areas of Texas but in general, Tamrun OL07 equals the most popular varieties in the absence of disease pressure and is superior in yield in the presence of Tomato spotted wilt virus and/or Sclerotinia minor. Seed size and 100 kernel weights for Tamrun OL07 fall between the larger Tamrun OL01 and the smaller Tamrun OL02.
It has been determined that a high oleic acid to linoleic acid ratio (O/L) in peanut imparts desirable traits into the peanut after it is roasted. Desirable attributes include longer shelf life of products, including peanut butter, peanut candies, and roasted peanuts in and out of the shell. Also, there are health benefits from eating more mono- and poly-unsaturated fat in the diet.
Application for Plant Variety Protection with the Title V option has been made and requires that the seed be sold in certified classes only. Foundation seed is available through Texas Foundation Seed Service through a non-exclusive royalty bearing licensing agreement. Licensees are also required to have on file a licensing agreement with the University of Florida Research Foundation, the holder of multiple patents for the High O/L gene contained in Tamrun OL07.
