ABSTRACT

The peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar DP-1 (Reg. No. CV-103, PI 633047) was developed by the University of Florida, Florida Agricultural Experiment Station and approved for release in 2002. Tested under the experimental designation UF97318, DP-1 has runner market-type seed and pod size with a runner growth habit. Under irrigation, it matures about 150 d after planting, which places it in the category of late relative maturity. Release of DP-1 was based on its resistance to spotted wilt caused by tomato spotted wilt tospovirus, white mold caused by Sclerotium rolfsii Sacc., and late leaf spot caused by Cercosporidium personatum (Berk. & M.A. Curtis) Deighton, as well as competitive pod yield and grade characteristics.
