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.

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.Maíz-Zea maysapplication/pdfspa‎‎Corporación colombiana de investigación agropecuaria - AGROSAVIAhttp://revistacta.agrosavia.co/index.php/revista/article/view/357/347Attribution-NonCommercial-ShareAlike 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-sa/4.0/http://purl.org/coar/access_right/c_abf2Revista Ciencia y Tecnología Agropecuaria; Vol 15 No 2 (2014); 173-182Corpoica H5: the first high quality protein (QPM) hybrid maize for Colombian eastern plainsCorpoica H5: primer híbrido de maíz amarillo de alta calidad de proteína (QPM) para la altillanura plana colombianaZea maysInteracción genotipo ambienteHibridaciónIndustria alimentariaTransitorioshttp://aims.fao.org/aos/agrovoc/c_8504http://aims.fao.org/aos/agrovoc/c_24577http://aims.fao.org/aos/agrovoc/c_3706http://aims.fao.org/aos/agrovoc/c_3020articleArtículo científicohttp://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/resource_type/c_6501info:eu-repo/semantics/articlehttps://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85ORIGINALVer_Documento_35153.pdfVer_Documento_35153.pdfapplication/pdf409050https://repository.agrosavia.co/bitstream/20.500.12324/35153/1/Ver_Documento_35153.pdf82f773c7c343384177343213cfe0c685MD51open accessTHUMBNAILVer_Documento_35153.pdf.jpgVer_Documento_35153.pdf.jpgIM Thumbnailimage/jpeg12986https://repository.agrosavia.co/bitstream/20.500.12324/35153/2/Ver_Documento_35153.pdf.jpg69696205f56c5fecbb9aab3ea2726142MD52open access20.500.12324/35153oai:repository.agrosavia.co:20.500.12324/351532024-02-09 14:04:14.297open accessAgrosavia - Corporación colombiana de investigación agropecuariabac@agrosavia.co
