’Desert Song’ Flor de Junio (FJ) common bean (Phaseolus vulgaris L.) (Reg. No. CV-308, PI 673424) and ’Gypsy Rose’ Flor de Mayo (FM) common bean (Reg. No. CV-309, PI 673425) cultivars, developed by Michigan State University AgBioResearch, were released in 2014 as high-yielding FJ and FM seed types adapted to northern production zones. Both cultivars were developed using the pedigree breeding method to the F-4 generation followed by pure line selection for disease, agronomic, seed, and cooking traits. In 4 yr of field trials, Desert Song yielded 3468 kg ha(-1), flowered in 41 d, and matured in 100 d on average. Plants averaged 48 cm for canopy height, with lodging resistance score of 3.2 and seed weight of 36.2 g 100 seed(-1). In the same 4 yr of field trials, Gypsy Rose yielded 3761 kg ha(-1), flowered in 49 d, and matured in 105 d on average. Plants averaged 49 cm for canopy height, with lodging resistance score of 3.3 and seed weight of 30.4 g 100 seed(-1). Both cultivars combine high yield potential with adaptation to northern production areas. They possess resistance to Bean common mosaic virus and intermediate resistance to race 22: 2 of bean rust [incited by Uromyces appendiculatus (Pers.:Pers.) Unger]. Each cultivar produces seed that meets industry standards for packaging and canning in the respective FJ and FM seed classes.
