By: Contributor(s): Material type: TextTextPublication details: Mexico, DF (Mexico) CIMMYT : 2003Description: p. 112-113Subject(s): DDC classification:
  • 631.53 BOO
Summary: Some essential amino acids are nutritionally limiting in maize-based diets. We have initiated a program to alter the amino acid content in maize using the traditional plant breeding method of recurrent selection The potential of this method to improve maize populations for their composition in two nutritionally limiting amino acids, Methionine (Met) and Tryptophan (Trp ), was tested. The objectives of this study are (1) to determine the effect of selection on the amino acid composition in maize, (2) to conduct divergent selection for both Met and Trp, and (3) to determine the effect of selection on the nutritional value of the populations.
