GOMEZ MONTIEL, Noel Orlando et al. Improved blue corn variety ‘V-239AZ’ for the regions semi-warm of Guerrero. Rev. Mex. Cienc. Agríc [online]. 2017, vol.8, n.8, pp.1905-1910. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v8i8.714.

The INIFAP Genetic Improvement Program, based in Iguala of the Independencia, Guerrero, has released the first improved creole variety of blue maize ‘V-239AZ’ with adaptation to the semi-warm regions of the states of Guerrero, Oaxaca and Puebla. After five cycles of convergent - divergent mass selection that gave origin to this variety, it was possible to reduce the agronomic problems of the original creole, such as higher plant height and ear, susceptibility to lodging, high asynchrony between its blooms and uninform grain color, giving place in 2016 to its liberation.

Palabras llave : adaptation; genetic variability; improved maize; yield.
