Allelic variation is essential for genetic improvement of crops. In this thesis, a genome-enabled strategy for the targeted utilization of landraces was developed for improvement of quantitative traits. Haplotypes with favorable effects on target traits and absent in a broad panel of 65 breeding lines, were mapped in more than 1,000 doubled haploid (DH) lines derived from three pre-selected maize landraces. DH lines carrying these haplotypes outperformed breeding lines. Most haplotypes showed stable effects across populations and environments and limited effects on undesired traits.
