MAGDALENO-HERNANDEZ, Edgar et al. Traditional selection of creole maize seed. agric. soc. desarro [online]. 2016, vol.13, n.3, pp.437-447. ISSN 1870-5472.

This study had the purpose of understanding the method for maize (Zea mays L.) seed selection, Creole variety, and the physical characteristics of the corncob. The peasants of the community of Pueblo Nuevo located in Valle de Acambay, Estado de México. When choosing their seed, it was detected that they cultivate 100 %; they use Creole maize, of the conic type, for their sowing. A survey was carried out with 50 peasant heads of households. There is preference for selecting the corncob for seed after performing the harvest (92 %). Regarding the characteristics of the corncob, 70 % of the peasants selected their seed in function of the size, followed by thin stalks (18 %), health (8 %), and a color different from white maize (4 %). When selecting the seed they prefer to use the central (70 %) and basal (26 %) part of the corncob. The knowledge of the genetic origin of the maize that peasants in the zone manage is relevant for the study and the characterization of its phenotypical diversity, genetic improvement, and, above all, the maize's in situ conservation.
