Exploración de germoplasma nativo de maíz en Nuevo León, México

Abstract: En diversos estados del país, como Nuevo León, aún en la actualidad existe una considerable diversidad de variedades de maíz (Zea mays L.) que no han sido exploradas ni estudiadas suficientemente y cuya recolección es necesaria como fuente de germoplasma. El objetivo del presente trabajo fue realizar una recolecta de poblaciones nativas de maíz en las regiones de la Gran Llanura de Norteamérica, Llanura Costera del Golfo Norte y Sierra Madre Oriental, para su conservación ex situ, caracter… Show more

“…with Cónico Norteño, which had not been identified in previous collections (Acosta-Díaz et al, 2014;CONABIO, 2019). Conversely, this time the Tabloncillo and Olotillo landraces were not found, which had previously been reported in the studied zone (Acosta-Díaz et al, 2014;CONABIO, 2019). It is possible that a loss of germplasm has occurred in the last few years, but a more precise verification of this would be needed.…”

“…In this region maize constitutes 93% of the cultivated dryland surface, with a kernel yield that ranges between 0.34 and 1.1 t ha 1 (SIAP, 2019). Acosta-Díaz et al (2014) detected the presence of five races in this region: Cónico Norteño, Olotillo, Ratón, Tuxpeño, and Tuxpeño Norteño. But there are still unexplored zones in the region, such as the Gral.…”

“…Esta época coincide con el periodo de menor disponibilidad de forraje (15). El clima predominante es templado subhúmedo frío Cb (w1) (i') w", con lluvias en verano, una precipitación promedio anual de 600 a 800 mm y una temperatura media de 12 a 18ºC (16). El manejo de las cabras se realizó de acuerdo con un esquema de producción extensivo, donde el manejo sanitario se limita a la disponibilidad de recursos económicos del productor, el cual incluye solo el control de parásitos internos y externos cada seis meses.…”
