Journal of Plant Registrations, Vol. 1, No. 2, September 2007 125 ‘Hull’ peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) (Reg. No. CV-98, PI 633048) cultivar was developed by the University of Florida Agricultural Experiment Station (FAES) and was approved for release in 2002. Hull is a medium-late maturity (approximately 145 d), runner market-type peanut cultivar with high-oleic (~80% C18:1) fatty acid oil chemistry in the seed. Hull has good resistance to spotted wilt caused by Tomato spotted wilt virus (TSWV), a Tospovirus. Tested experimentally as UF98326 (89xOL28-H0l-7-4-1-2-b3-B), Hull originates from a 1989 three-way cross made at the North Florida Research and Education Center (NFREC), Marianna, FL, between the F1 ‘Southern Runner’ (Gorbet et al., 1987) and the FAES high-oleic breeding line F435-HO (Norden et al., 1987), used as the female parent, and pollinated with the FAES unreleased breeding line UF81206. UF81206 is a selection from PI203396 × F427B-3-1-7-4-B and has good to excellent multiple disease resistance to late leafspot [Cercosporidium personatum (Berk. & M.A. Curtis) Deighton], stem rot (Sclerotium rolfsii Sacc.), rust (Puccinia arachidis Speg.), and TSWV (Gorbet and Shokes, 2002). The cross was made to provide material to select for high-oleic fatty acid oil chemistry with good pod and seed yields, good grades with medium to late maturity, and good multiple disease resistance. The main diseases selected for resistance were TSWV, late leaf spot, and stem rot or white mold (Gorbet, 2003). Hull originates from a single high-oleic seed from a F1 plant from the above-mentioned three-way cross. Hull was developed from an individual plant pedigree selection program conducted at the Marianna NFREC under unsprayed (leaf spot) management with irrigation and good fertility. Single plant selections were made in unsprayed (for leafspot control) fi eld tests in the F2 to F6. Selection focused on runner market types and good yields, with resistance to TSWV and late leaf spot. Hull was fi rst yield tested in F7 at Marianna in 1996 under unsprayed fi eld conditions (Gorbet, 2003). Registration of ‘Hull’ Peanut
