Resumen

ACOSTA GALLEGOS, Jorge Alberto et al. Flor de Mayo Eugenia, new bean cultivar for irrigated and rainfall conditions in Central Mexico. Rev. Mex. Cienc. Agríc [online]. 2010, vol.1, n.5, pp. 751-757. ISSN 2007-0934.

Within 'Flor de Mayo' bean type, the 'media oreja' subtype is becoming important in North-Central México; this last type has a mid-size elongated seed with showy pink color. A new bean cv. of 'media oreja' subtype is described: Flor de Mayo Eugenia (FME). FME was derived from an interracial cross between Flor de Mayo Anita (FMA) (Jalisco breed) and Rayado Rojo (Nueva Granada breed). The seed yield of FME under rainfall conditions varied from 0.8 to 2.0 t ha-1 and under irrigation the highest yield recorded was 3.8 t ha-1. The 100-seed weight of FME across different locations was significantly superior to the weight of FMA, 32 vs 26 g per 100 seeds under rainfall conditions and 35 vs 31 g per 100 seeds under irrigation conditions. In regard to seed quality, cooking time average of FME was 97 min, whereas the time of FMA was 109 min; protein content on dry weight basis was similar between both cultivars, 19%; as for iron content FME was superior to FMA with 6.1 vs 5 mg 100 g. FME is tolerant to the present races of rust in the Highland of Mexico, to antracnosis race 292 and tolerant to tizones common and the halo.
