0PI 638505'Southern Belle'Trifolium pratense L. Florida, United StatesW62005DEVELOPEDPRE 02/03/2005CultivarSuperior to all other known red clover cultivars in resistance to the several root-knot nematode species. In a greenhouse evaluation, Southern Belle had lower galling and egg mass scores than Cherokee. Also shows lower powdery mildew ratings. Equal to Cherokee in northern anthracnose susceptibility. Has annual and five year mean total seasonal dry matter yields not different from Cherokee, and similar to yield performance data. The primary yield advantage of both Southern Belle and Cherokee over other red clover cultivars when grown at more southern locations has been in first harvest yields, due to the non-dormancy (earlier spring growth) of Southern Belle and Cherokee. First harvest yields were approximately 1000 kg/ha greater than cultivars developed at more northern locations. Total seasonal yields at southeastern locations usually equal or exceed central and northern USA developed cultivars. At Gainesville, FL, over 70% of spaced plants flowered before plants of any cultivars developed at more northern locations.1671123PI 638505
