Abstract:

En un análisis efectuado a aproximadamente 1,200 accesiones de maíz nativo colectadas en un proyecto financiado por CONABIO (Comisión Nacional para el Conocimiento y Uso de la Biodiversidad) en México, no se encontró evidencia de materiales genéticamente modificados. Los investigadores del CNRG trataron de amplificar el promotor 35S utilizado comúnmente en la modificación genética de maíz y no encontraron evidencia de este evento en ninguna de las muestras estudiadas.
En los archivos "Registro de Colecta", el número que se encuentra en la columna denominada "Material", corresponde a la ID (identificación individual de cada colecta) definida en la primera columna de la base de datos del proyecto global de maíces nativos de la CONABIO, la cual está disponible en formatos .mdb y .xls en la Liga http://www.biodiversidad.gob.mx/genes/proyectoMaices.html.

An analysis of approximately 1200 maize landraces collected under a CONABIO funded project in the 2000’s in Mexico did not find any evidence of genetically modified materials. Researchers at CNRG attempted to amplify the 35S promoter commonly used in the genetic modification of corn and did not find any evidence of this event in any of the samples tested.
In the “Registro de Colecta” files, the number in the column called “Material” corresponds with the collection ID defined in the first column of the database of the CONABIO Proyecto global de maíces nativos; “Base Maices nativos”, which is available in .mdb and .xls format from http://www.biodiversidad.gob.mx/genes/proyectoMaices.html.

Evaluation of Seeds of Discovery-MasAgro Biodiversidad Testcross Germplasm in 2011B in Tlaltizapán, Méxicoby Willcox, Martha; Guadarrama Espinoza, Armando ; Chepetla Calderon, Daniel ; Sanchez, Ciro; Burgueño, Juan
Abstract:

Testcrosses generated using accessions from the CIMMYT Maize Germplasm Bank were planted in soils with low and optimal levels of nitrogen, however several experimental factors may have affected the level of nitrogen available to the plants in the two fields. First, the low nitrogen field had only been subjected to three years of nitrogen depletion and the absolute level of nitrogen present in the soil was not measured. Second, stover from the previous season was left on the optimal nitrogen field but not the low nitrogen field. This stover may have contributed to the sequestration of nitrogen and may have reduced that amount available for the maize plants. Third, a foliar ferrous sulfate solution was applied to the low nitrogen materials but this application also contained seaweed agar. It may have introduced higher than expected levels of nitrogen to the low nitrogen experiment. In addition, there was some significant bird damage to some of the plots.

Based on the factors that interfered with the proper execution of a fully controlled experiment, the phenotypic results from this experiment do not represent the expected results for low nitrogen conditions and these data should be not be used to evaluate the low nitrogen adaptation of these materials.

The analyzed BLUPs from this trial are presented in this study.

Fenotipificación De Trigo Para La Identificación De Germoplasma Con Alto Potencial De Rendimiento Y Tolerancia A Sequía Y Calorby Saint Pierre, Carolina; Molero, Gemma; Cossani, Mariano; Sonder, Kai; Salinas, Gilberto
Abstract:

Propósito general de aprendizaje:
Al finalizar el taller, los participantes serán capaces de utilizar equipo científico, protocolos y aplicaciones informáticas modernas para fenotipificar germoplasma de trigo, con caracteres relevantes para su adaptación a sequía y calor y para aumentar el potencial de rendimiento de grano.
A través de un taller se fortalecerán capacidades en los participantes para que caractericen fenotípicamente germoplasma de trigo; para lo cual se utilizarán las técnicas didácticas: simulación y juego, exposiciones, paneles de discusión y aprendizaje basado en problemas. Se desarrollarán los siguientes ejes temáticos:
1. Cambio climático: caracteres prioritarios del trigo para México.
2. Fenotipificación de materiales de amplia base genética y en proceso de mejoramiento: bases conceptuales y metodológicas
3. Métodos y protocolos para la caracterización fenotípica de la tolerancia a sequía y calor y potencial de rendimiento de grano.
4. Registro de datos fenotípicos con la herramienta informática KDSmart
