Interpretive Summary:

Technical Abstract: Genetic maps are useful tools for both basic research and plant improvement. Close association of genetic markers with genes controlling economically important traits allows for indirect selection, avoiding often time-consuming and expensive phenotypic evaluations. As a result, detailed genetic maps have been created for almost all economically important plants and many important traits have been tagged. Onion has lagged behind other major crops because of relatively few public-sector researchers, long generation time, and high cost of developing segregating families. With the advent of next generation DNA sequencing, large numbers of codominant markers have become available. The onion research community should now work collaboratively to produce and share useful genetic and genomic resources for onion, including diverse doubled-haploid lines, readily accessible sequence and bioinformatic resources, and large segregating families for detailed genetic mapping and phenotyping.
