Abstract
Polyploid breeding is an important means for creating elite varieties for the development of poplar plantations. However, polyploid poplars are rare in natural stands. In this study, we established an analytical toolkit to perform marker-aided selection of polyploid poplars. This toolkit contains 12 SSR primer pairs with sites located in the exonic DNA regions and resulting amplified microsatellites in the intronic/intergenic regions. Highly conserved primer pairs were selected by testing in eight species from four poplar sections. The amplified loci’s variability was examined using trees from a germplasm collection of Populus deltoides. Subsequently, copy numbers amplified by the highly variable primers were experimentally determined using progeny of a full-sib diploid pedigree. Based on the above tests, a subset of primers were finally selected and used for marker-aided selection of polyploid poplars from a set of natural Populus tomentosa stands. The reliability of the established analytical toolkit was further verified using a flow cytometer. We established a fast and reliable technique to screen polyploid poplars from natural stands.
