Agronomic characterization of pigmented native corn populations (Zea mays L.)

Objective: To characterize agronomically 52 populations of pigmented native corn (Zea mays L.) from Coahuila, Mexico, in order to identify varieties with outstanding agronomic potential and establish an improvement program for grain yield, the ability adapt, superior nutritional bioactive content. Design/Methodology: Two experiments were evaluated through incomplete block design lattice alpha arrangement, two localities that are representative agricultural area southeastern Coahuila: a) Yellow populations, mostly Tuxpeño, Ratón Tuxpeño Norteño; b) Anthocyanin (blue, red purple), represented primarily by Cónico Norteño, Elotes Cónicos Ratón. Results: There is environmental effect contrasts between localities, differences yield up 78%; 25 days difference flowering, 53 cm plant height, seven plants without cobs. The response was product each locality. yellow due their expression both landraces Tuxpeño: COAH068, COAH089, COAH177 COAH215, Celaya: COAH075. anthocyanin Ratón: COAH23 COAH203; Cónicos: COAH246 COAH019; Occidentales: COAH021; addition, study found adapted a Conclusion: Among diversity there can be basis improving production, quality grain, therefore, its byproducts.
