GARZA-GARCIA, Ramón; JACINTO-HERNANDEZ, Carmen y GARZA-GARCIA, Dagoberto. Bayo Azteca, first improved bean variety with resistance to Apion godmani Wagner. Rev. Mex. Cienc. Agríc [online]. 2010, vol.1, n.5, pp.651-656. ISSN 2007-0934.
Bayo Azteca, the first improved bean variety (Phaseolus vulgaris L.), with resistance to an insect plague, has been obtained via multiple crossing by bean program of the Valley of Mexico Experimental Station (CEVAMEX), of the National Research Forestry, Agriculture and Livestock Institute (INIFAP), which required a long process of genetic improvement. Bayo Azteca is the first improved variety resistant to bean pod weevil (Apion godmani Wagner), which is a curculionidae that attacks beans in template zones of the Central Highlands of Mexico and causes 50-90% losses. Similar to other varieties, the Bayo Azteca is resistant to anthracnose [Colletotrichum lindemuthianum (Sacc & Magn.) Briosi & Cav.] and common blight [Xanthomonas campestris pv phaseoli (Smith) Dye]. The new variety was developed for Central Highlands of Mexico for an altitude that ranges from 1 800 to 2 300 masl. Its growth habit is type III non-determined, short guides, and white flower; its sheaths are of medium and large sizes with 5 or 6 medium size grains each, it has a high potential yield and phenological plasticity. In the Highlands, it is of intermediate earliness (it takes from 102 to 118 days to maturity); Bayo Azteca is also of fast cooking and rich in proteins.
