TAMSPAN 90 - was developed and released by the Texas Agricultural Experiment Station and the USDA in 1990. It was derived by mass selection from a population of the cross Toalson X UF73422 made in 1975. Tamspan 90 is a Spanish type peanut with good resistance to pod rot and Sclerotinia blight. It is very similar in growth and appearance to the variety Starr and is higher yielding, especially when Sclerotinia blight is present.

TAMRUN 96 - was developed and released by the Texas Agricultural Experiment Station. It yielded 14.3% better than Florunner in 33 irrigated tests in Texas from 1990-1995. It yielded 17% better than Florunner in nine regional tests in the Southwest and Southeast U.S. The shelling percentage and grade tends to be slightly lower for Tamrun 96 compared to Florunner. However, the average difference in grade is less than 1%, which is more than offset by the increased yield. The seed size of Tamrun 96 is slightly larger than Florunner. Compared to Florunner, Tamrun 96 appears to exhibit better performance under pressure from several diseases including tomato spotted wilt, southern blight, sclerotinia, and pod rot. Chemical properties of Tamrun 96 are similar to Florunner. This variety is protected under PVP title V.

FLORUNNER - is a runner-type peanut released by the Florida Agricultural Experiment Station and is adapted primarily to the long growing season conditions such as those in Florida and Georgia. Its plant growth is more prostrate, foliage less dense, and its seed matures more uniformly than Early Runner. Pods are concentrated near the central branches or tap root. Seedling vigor and leafspot disease ratings of Florunner are similar to those of Early Runner. The incidence of pod rot has been slightly less for Florunner. Florunner has a high percentage of sound mature kernels, desirable oil quality characteristics, and good processing characteristics.

NemaTAM - is a runner peanut that has excellent resistance to the root-knot nematode species Meloidogyne arenaria and Meloidogyne javanica. The line was derived from a backcrossing program using Florunner as the recurrent parent, so the line is essentially Florunner with the nematode resistance gene(s) incorporated.

The plants look very much like Florunner and have much the same phenotypic characters. Leaflet size and color, mainstem height, lateral branch length, pod shape and size, and seed shape and size are almost identical to Florunner. The pods of NemaTAM are mostly two seeded, but occasional three seeded pods occur. NemaTAM has the typical Florunner growth habit and life span. It has mostly alternate branching pattern, but with some sequential. It has an occasional flower on the mainstem, and plant color is the same as Florunner. The chemical analyses of NemaTAM are essentially the same as Florunner, and yields and grades are equal to Florunner except under root-knot nematode pressure, in which case yields of NemaTAM will be much higher than Florunner, depending upon the level on nematode infestation.

NemaTAM was officially released in March of 2002 and application for Plant Variety Protection with Title V has been filed. This seed may be sold in certified classes only. Seed is available for 2002 from the Texas Foundation Seed Service through a non-exclusive licensing agreement.

Tamrun OL 01 - The new peanut line named Tamrun OL 01 is a runner type peanut with large vines and a dark green color. The plants are not as large as Tamrun 96, but are larger than Florunner. In a thick planting (more than 2 seed per foot of row) the main stem is not highly prominent, but is visible. The plant color is a slightly darker green than Florunner, but is only discernable when the varieties are growing side by side. There is less than ¼ of 1% variegated plants and less than ½ of 1% has an erect appearance in a thick planting. The pods and seed are much larger than Florunner and a little larger than Tamrun 96. The seed weigh approximately 70g per 100 seed. The data on oil analyses indicates that the line has a high O/L ratio. Average O/L to date and run about 27:1. Maturity range is approximately equal to Florunner. Occasional seed which have a split seed coat are present, <1%. Disease resistances have been near equal to Tamrun 96.

Tamrun OL 01 was released in March of 2002. Application for Plant Variety Protection with the Title V option has been filed and requires that the seed be sold in certified classes only. Seed will be available through the Texas Foundation Seed Service through a non-exclusive royalty bearing licensing agreement. Licensees will also be 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 OL 01.

OLin - OLin is named for the late TAES Peanut Breeder Olin Smith. Dr. Smith was very instrumental in the development of many new peanut varieties adapted to the Southwest U.S. OLin is a Spanish peanut that has an elevated O/L FFA (free fatty acid) content. OLin has an erect growth habit with sequential branching and flowers on the mainstem. Mature plants will have main secondary lateral branches (9+), originating at the basal nodes. The leaf size and plant color are similar to Tamspan 90, but slightly smaller in overall height. This is difficult to determine without side-by-side comparisons. Pod and seed size are slightly smaller than Tamspan 90, and occasional three seeded pods occur. The yield of OLin will be slightly less than Tamspan 90, but grades (TSMK) will be slightly higher.

OLin was released in March of 2002. Application for Plant Variety Protection with the Title V option has been filed and requires that the seed be sold in certified classes only. Seed will be available from the Texas Foundation Seed Service through a non-exclusive royalty bearing licensing agreement. Licensees will also be 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 OLin.

Tamrun OL02 is a high O/L runner peanut that has excellent yield and grade potential and some of the disease tolerance that is found in Tamrun 96. Tamrun OL02 is a sister line to Tamrun OL01 (Tx977006) but it has a smaller seed that is more typical of currently grown runner cultivars such as Tamrun 96. Tamrun OL02 also has lower sugar content than Tamrun OL01. The objective in releasing Tamrun OL02 is to provide the peanut growers of Texas, and especially West Texas, a runner variety which has high O/L and some ability to withstand effects of soil borne diseases and tomato spotted wilt virus, but with a smaller seed size and lower sugar content than Tamrun OL01.

It has been determined that a high oleic acid to linoleic acid ratio (O/L) in peanut (and other crops) imparts desirable traits into the peanut (and other crops) after it is roasted. Desirable attributes include longer shelf live of products, including peanut butter, peanut candies, and roasted peanuts in and out of the shell. Also, there are definite health benefits from eating such products, i.e., more mono- and poly-unsaturated fat in the diet.

Limited quantities of Foundation Seed were available for spring planting 2003, and Certified Seed should be commercially available for spring planting in 2004. Application for Plant Variety Protection with the Title V option has been filed and requires that the seed be sold in certified classes only. Seed will be available through the Texas Foundation Seed Service through a non-exclusive royalty bearing licensing agreement. Licensees will also be 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 OL02.
