Narrative
ReGen is a dormant variety with fall dormancy similar to the FD3 check. Its flower color is 93% purple and 7% variegated, and pod shape is 96% tightly coiled and 4% loosely coiled. ReGen has high resistance to Fusarium wilt [caused by Fusarium oxysporum Schlecht. f. sp. medicaginis (Weimer) Snyd. and Hans.], Verticillium wilt (caused by Verticillium albo-atrum Reinke and Berth.), and anthracnose (Race 1) (caused by Colletotrichum trifolii Bain and Essary); resistance to bacterial wilt [caused by Clavibacter michiganensis subsp. insidiosum (McCull.) Davis et al.] and Phytophthora root rot (caused by Phytophthora megasperma Drechs. f. sp. medicaginis Kuan and Erwin); and low resistance to Aphanomyces root rot (Race 1).

Pedigree
Description:
ReGen is the result of a three-way population cross. The initial cross was between two plant populations: Seedway 9558 and germplasm related to Iroquois, Saranac AR, Oneida VR, and Vertus, followed by phenotypic recurrent selection for multiple disease resistance and selection in the field for plant vigor, agronomic traits, and higher forage quality. Progenies of this population cross were crossed with a population derived from Magnum III after selection for resistance to multiple diseases.
