Variación intra-racial de maíces nativos del altiplano de Puebla, México

Diversity among native maize populations in the highlands of the state of Puebla, Mexico has been studied through the association of those populations with some of the reported maize races; however, population variation within races has been little studied.

description_str_mv Diversity among native maize populations in the highlands of the state of Puebla, Mexico has been studied through the association of those populations with some of the reported maize races; however, population variation within races has been little studied. The aim of the study was to characterize morphologically populations of native maize from the highlands of the state of Puebla and to define relationships among and within races to which they belong. In 2012, 41 native maize populations from the valleys of Serdan, Libres-Huamantla and Puebla were evaluated; 19 representative-race popula- tions, two commercial and two experimental populations were included as controls in the trials. Forty morphological variables were recorded and an analysis of variance was applied, as well as multivariate techniques such as discriminant stepwise, principal component and cluster analyses. Statistical differences among populations for most of the variables were detected and it is considered as an indicator of diversity. Native populations were associated with Chalqueño, Conico, and Elotes Conicos races and with sub-race Elotes Chalqueños. Variation among and within groups was identified, suggesting that the environment and the dynamic process of selection from the farmers on native maize populations in the highlands of the state of Puebla, support an important variation among and within groups representative of the maize races in this area. On the basis of the identified variation, breeding and conservation in situ of maize races can be carried out.
En el altiplano del estado de Puebla, México, se ha estudiado la diversidad existente en poblaciones nativas de maíz a través de la asociación de éstas con alguna de las razas reportadas para valles altos; sin embargo, la variación de las poblaciones dentro de esas razas ha sido poco estudiada. El objetivo del estudio fue caracterizar morfológicamente a poblaciones de maíces nativos del altiplano del estado de Puebla y definir las relaciones existentes entre y dentro de las razas a las que pertenecen. En 2012 se evaluaron 41 poblaciones nativas de maíz procedentes de las regiones de los valles de Serdán, Libres-Huamantla y Puebla; se incluyeron 19 testigos raciales, dos testigos comerciales y dos variedades experimentales. Se registraron 40 variables morfológicas y se aplicó un análisis de varianza, además de técnicas multivariadas como el análisis discriminante stepwise, componentes principales y de conglomerados. Se detectaron diferencias estadísticas entre poblaciones para la mayoría de las variables, lo que se considera un indicador de diversidad. Las poblaciones nativas se asociaron con las razas Chalqueño, Cónico, Elotes Cónicos y con la sub-raza Elotes Chalqueños. Se identificó variación dentro de los grupos resultantes, lo que sugiere que el ambiente y el proceso dinámico de selección de los agricultores sobre las poblaciones nativas de maíz en el altiplano del estado de Puebla, favorecen una variación entre y dentro de grupos representativos de las razas en esta zona. La variación identificada puede ser la base para el mejoramiento y conservación in situ de razas de maíz.
