| 0 | PI 642851 | 'TAMRUN OL07' | Arachis hypogaea L. subsp. hypogaea var. hypogaea | Texas, United States | PVPO | | Not Available | 2006 | DEVELOPED | 05/2006 | | | | | Cultivar | Tamrun OL07 is a runner market-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar with a high O/L ratio and having good yield potential. The new variety was tested as Tx033630 and was released by the Texas Agricultural Experiment Station in May 2006. Tamrun OL07 has a larger vine size than that of Tamrun OL 01. The mainstem height is, on average, 13.9cm taller than Tamrun OL 01 (p!\ 0.01) and the N+1 branch is 15.3cm longer (p!\ 0.01). The mainstem is apparent in most locations and seeding rates that we tested. The lateral branching is profuse like Tamrun OL 01 and the branching pattern is alternate, although not perfectly so. Leaf color is medium green, like Tamrun OL 01 (RHS 137A). Pods of Tamrun OL07 are mostly two seeded with a significantly smaller seed size than Tamrun OL 01 averaging 68.1 vs. 72.3g/100 seed (p!\ 0.05), across all locations. Pod constriction between the seeds is moderate and no differences were detected between the two varieties in analysis of pod measurements. Disease ratings indicate that Tamrun OL07 has more resistance to TSWV than Tamrun OL 01, Tamrun OL 02, and Flavorrunner 458. Yield test in a South Texas TSWV nursery showed Tamrun OL07 with a significantly lower infection rate of 28.3% as compared to Tamrun OL 01, Tamrun OL 02, and Flavorunner 458 with ratings of 58.8%, 55.0%, and 74.1% respectively (p!\ 0.01). The lower disease ratings were reflected in higher yields as Tamrun OL07 yielded 5447 Kg/ha as compared to 4160 Kg/ha for Tamrun OL 01, 3508 Kg/ha for Tamrun OL 02, and 2313 Kg/ha for Flavorrunner 458. Disease ratings for Tamrun OL07 in the Central Texas Sclerotina blight nursery indicate that Tamrun OL 07 has more resistance than the check varieties. Analysis of test ratings from 2002 through 2005 show that Tamrun OL07 has an average Sclerotinia infection rating of 34.1% compared to Tamrun OL 01 with 46.0%, Tamrun OL 02 with 50.1%, and Flavorrunner 458 with 60.7% (p!\ 0.01). Grades were not different (p!\0.05). | 1702690 | PI 642851 |
