Interpretive Summary: Flor de Junio and Flor de Mayo represent unique dry bean market classes from Mexico. For de Junio seed has a red stripe on a cream background and Flor de Mayo seeds have speckled spots toward one side of an otherwise cream background. Few if any cultivars exist of these market classes for growing in the northern tier dry bean production states - CO, ID, MI, MN, MT, ND, NE, WA or WY. Desert Song and Gypsy Rose are new cultivars that were bred specifically for high yield and agronomic adaptation in the US. These cultivars will serve an expanding market for traditional Mexican dry bean market classes in U.S. due to the increasing Hispanic population from Mexico in the U.S.

Technical Abstract: ‘Desert Song’ Flor de Junio (FJ) common bean (Phaseolus vulgaris L.) (Reg. no. CV- , PI -) and ‘Gypsy Rose Flor de Mayo (FM) common bean (Reg. no. CV- , PI -) cultivars developed by Michigan State University AgBioResearch were released in 2014 as high-yielded yielding FJ and FM seed types adapted to northern production zones. Both cultivars were developed using pedigree breeding method to the F4 generation followed by pure line selection for disease, agronomic, seed and cooking traits. In 3-yr of field trials, Desert Song yielded 3522 kg ha-1, flowered in 41d and matured in 100 d on average. Plants averaged 48 cm in for canopy height, with lodging resistance score of 3.2 and seed weight of 36.2 g 100 seed-1. In the same 3-yr of field trials, Gypsy Rose yielded 3566 kg ha-1, flowered in 49 d and matured in 105 d on average.Plants averaged 49 cm in 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 necrosis virus (BCMNV) 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 in the respective Flor de Junio and Flor de Mayo seed classes.
