Narrative
Botanical Characteristics. Tamrun OL12 is a runner peanut, with spreading growth habit, and lacking flowers on the mainstem. The main stem is highly prominent, more so than the check cultivars Florunner or Flavorunner 458. Quality Analyses. Tamrun OL12 was significantly more mature than Flavorunner 458 and Tamrun OL02 in all four years of testing, with an overall mean of 52.8 percent mature pods. Tamrun OL12 had from 17.4 (in 2007) to 28.0 (in 2006) percentage points more mature pods than Flavorunner 458, and from 26.1 (in 2009) to 35.7 (in 2008) percentage points more mature pods than Tamrun OL02. The fruity-fermented attribute mean of Tamrun OL12 (0.43) across years was significantly lower than for Florunner (0.88) (p=0.018). Other flavor attributes measured in 2008 or 2009 were similar between Tamrun OL12, Florunner, and Flavorunner 458. Gas chromatographic analysis of oil from plants increased at the Texas Tech Farm in 2010 demonstrated a mean oleic:linoleic ratio of 22.7:1, with oleic and linoleic proportions of 79.2% and 3.85% of total fatty acids. Tamrun OL12 had lower sugar contents (5.4% and 5.6%) in 2008 and 2009 than Flavorunner 458, Tamrun OL02, and Florunner. There was no significant difference in oil concentration between Tamrun OL12 and Flavorunner 458 and Tamrun OL02 in either year. There were no differences in blanchability among Tamrun OL12, Tamrun OL02, Flavorunner 458, or Florunner for seeds harvested from 2009 field plots. Agronomic Performance. Yield of Tamrun OL12 was similar to the check cultivars, with no significant differences in yield among entries by year or across years. Mean seed size of Tamrun OL12 was 65.6g across years, similar to Flavorunner 458. This seed size was smaller than the 71.1g of Tamrun OL02. Tamrun OL12 had a mean 73.9% total sound mature kernels. This was numerically less than Flavorunner 458, and numerically higher than Tamrun OL02, but differences were not significant statistically.

Pedigree
Description:
Tamrun OL12 was produced from a cross between BSS56 and Tx966025, made in 2000. BSS56 is a spanish landrace from West Africa. Individual seeds of breeding line Tx036925 were selected and planted in 2005. Replicated line tests were performed from 2006 to 2009 in West Texas. Tx966205 was a high-oleic runner breeding line, produced from a cross between SunOleic 95 and Tx935411. Tx935411 was derived from a selection of Tx92586, which resulted from a cross between Marc-1 and Southern Runner.
