Abstract

A great number of maize varieties introduced from central American areas were tested for yield in Nigeria.

A “bulk” variety composed from ten “Trinidad” varieties was grown in trials all over Nigeria and later chosen as source for an improvement programme, using the topcross method and intercrossing the best lines to produce a synthetic variety. The synthetic was ultimately composed from nine ear samples.

On comparing the third generation to the first and second it was apparent that it maintained its improved production through the first three generations. Its general yield level was raised by 10 to 13% over that of the parent variety.

A description of the synthetic called ES1, is given.
