MARQUEZ SANCHEZ, Fidel. Alternatives for mass selection and combined selection of half families in maize. Rev. Mex. Cienc. Agríc [online]. 2011, vol.2, n.2, pp.289-292. ISSN 2007-0934.

In this work alternative methods to carry out bulk and family selection in corn are described. The aim of mass selection is to diminish difference among effects of genetic-environmental interaction between plants and it is proposed to make selection of the best contiguous ears along complete furrow. In the method of combined selection of half siblings families, if detasseling is not applied the derived endogamy of the self-fecundation is not affected, which means an important saving in manpower payment.
