Corpoica H5: the first high quality protein (QPM) hybrid maize for Colombian eastern plains

Colombia has an annual deficit of maize to meet the feed industry. In 2012, the country produced only 20.2% of the corn required by the industry; 1.0% of this production is obtained on the Colombian high plains (20,000 hectares); however, this region has an area of 500,000 hectares suitable for grow...

description	Colombia has an annual deficit of maize to meet the feed industry. In 2012, the country produced only 20.2% of the corn required by the industry; 1.0% of this production is obtained on the Colombian high plains (20,000 hectares); however, this region has an area of 500,000 hectares suitable for growing corn. To meet domestic demand, the government implemented the National Maize Plan (Plan País Maíz): a promoting and research strategy to assess and identify hybrids with yield and quality attributes that allow the competitiveness of this crop. In this context the present research was conducted, which identified the maize hybrid H5, with the following characteristics: high quality protein; grain yield of 5.05 t/ha, statistically similar to that obtained with commercial controls; male and female flowering of 56 and 57 days; period from planting to harvest of 112 days; plant height and cob of 185 and 94 cm,respectively; resistance to stem and root tumble, and to Cercospora sp. and Phaeosphaeria sp. Hybrid H5 showed per 100 g of protein, 4.10 g of lysine and 0.87 g of tryptophan; these values were higher by 1.7 and 2.0 times than those obtained by conventional maize (P30K73) having 2.32 g of lysine and 0.43 g of tryptophan. These characteristics of crystalline grain texture and high quality protein confer it commercial recommendation, because it is appropriate for the feed industry.

Colombia tiene un déficit anual de maíz para satisfacer la industria de alimentos balanceados; en el 2012, produjo solo 20,2% del maíz requerido por la industria, y 1,0% de esta producción se obtiene en la altillanura plana (20.000 hectáreas); no obstante, esta región tiene una extensión de 500 mil hectáreas aptas para el cultivo del maíz. Para satisfacer la demanda nacional, el gobierno implementó el Plan País Maíz, una estrategia de fomento e investigación para la evaluación e identificación de híbridos con atributos de rendimiento y calidad que permitan la competitividad de este cultivo. En ese contexto se realizó la presente investigación, que permitió identificar el híbrido de maíz H5 con las siguientes características: alta calidad proteínica; rendimiento de grano de 5,05 t/ha, estadísticamente igual al obtenido con los testigos comerciales; floración masculina y femenina de 56 y 57 días; período de siembra a cosecha de 112 días; altura de planta y de mazorca de 185 y 94 cm, respectivamente; y resistencia al volcamiento de tallo y raíz y a Cercospora sp. y Phaeosphaeria sp. El híbrido H5 presentó por cada 100 g de proteína 4,10 g de lisina y 0,87 g de triptófano; valores superiores en 1,7 y 2,0 veces al obtenido por el maíz convencional (P30K73) que presenta 2,32 g de lisina y 0,43 g de triptófano. Estas características de textura de grano cristalino y alta calidad proteínica le confieren recomendación comercial, por ser apropiado para la industria de alimentos balanceados.
