A Method of Identifying Lines for Use in Improving Parents of a Single Cross¹

A method for identifying inbred lines containing dominant alleles affecting a quantitative trait, which are not already present in an elite single cross, was developed. If the elite single cross is designated P₁ x P₂ and the lines to be tested P_w, the expression µG = [(P₁ x P_w) + (P₂ x P_w) – P₁ – P₂ – P_w – (P₁ x P₂)]/4 is an estimate of the relative number of loci in P_w which contain favorable alleles not present in P₁ or P₂. Results from applying the method to a set of corn (Zea mays L.) grain yield data suggest the method may be useful in applied breeding programs.

Key Words: Zea mays L. • Quantitative genetics • Corn breeding
