Registration of ‘Tamrun OL11’ Peanut

Le résumé fourni par la source

‘Tamrun OL11’ (Reg. No. CV‐118, PI 665017) is a high‐yielding, high‐oleic, runner‐type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar that has resistance to Sclerotinia minor Jaggar) and improved grade attributes over previously released runner‐type cultivars that are resistant to S. minor. It was tested under the experimental designation Tx055308 and released by Texas AgriLife Research at College Station, TX on 21 July 2011. Tamrun OL11 was derived from a single cross between Tx977116 F2:8, which has a high oleic‐oil content and resistance to Tomato spotted wilt virus, and the cultivar Tamrun 98, which has a normal oleic‐oil content and a high percentage of total sound mature kernels (TSMKs). Early selections were practiced using the pedigree selection technique. Initial yield testing began in the F3:5 generation in 2006 and continued through 2009 for a total of 25 multiple location trials. Tamrun OL11 performed equally as well as Tamrun OL07, which is resistant to S. minor, and was superior to the widely grown Flavorunner 458 cultivar for yield and disease resistance under high incidence of S. minor. Tamrun OL11 also performed equally as well as Flavor Runner 458 and was superior to Tamrun OL07 for the percentage of TSMKs. The objective of releasing this line is to provide growers with a cultivar that will yield and grade the same as the currently grown Flavor Runner 458 cultivar while reducing grower risk by maintaining the level of resistance to S. minor that the recently released Tamrun OL07 cultivar provides.
