Identificación de poblaciones de maíz grano como fuentes de tolerancia al frío para mejorar el maíz dulce

Abstract

[EN] One main problem for sweet corn adaptation lo the European Atlantic coast is that sweet corn germination and early development are poor under cold conditions. Field corn populations may be useful sources of cold tolerance for sweet corn. Our goal was to identify field corn populations as sources of favorable alleles for improving cold tolerance for sweet corn. Ten field corn populations were crossed to four sweet corn inbreds following a Design II mating design, and evaluated in cold chambers under average conditions of April at Pontevedra (Northwest of Spain). Combining ability, PTC and 1plμ‘ estimators of favorable alleles were calculated. Differences were significant for most traits within ail three groups: sweet corn inbreds, sweet corn hybrids and field corn populations, Sweet com inbred performance under cold conditions generally increased when crossed to field corn populations. The crosses of the sweet corn inbreds to the field corn populations were significantly different for proportion of emergence. The US Corn Bell Dent population ‘AS-3(HT)C3’ had the highest estimators of favorable alleles for proportion of emergence under cold conditions. The Spanish flint corn populations ‘Tuy’ and ‘EPS6(S)C2’ looked promising.

[ES] Uno de los principales problemas en la adaptación del maíz dulce a la costa atlántica europea es que la germinación y el desarrollo del maíz dulce son deficientes en condiciones de frío. Las poblaciones de maíz grano podrían ser útiles para mejorar la tolerancia del maíz dulce al frío. Nuestro objetivo era identificar poblaciones de maíz grano como fuentes de alelos favorables para mejorar la adaptación del maíz dulce. Diez poblaciones de maíz grano fueron cruzadas con cuatro líneas de maíz dulce siguiendo un diseño II de North Carolina, y evaluadas en cámaras frías en las condiciones medias de Abril en Pontevedra. Se calculó ACG, PTC y 1plµ`. Las diferencias fueron significativas para la mayoría de los caracteres entre líneas dulces, híbridos dulces y poblaciones dulces. La tolerancia al frío de las líneas dulces aumentó al cruzarse con poblaciones grano. Los cruzamientos entre líneas dulces y poblaciones grano difirieron significativamente para proporción de germinación. La población americana “AS—3(HT)C3” tuvo los mayores estimadores de alelos favorables para proporción de germinación en condiciones frías. Las poblaciones lisas españolas “Tuy" y “EPS6(S)C2“ resultaron prometedoras.
