Genetic mapping in durum wheat (Triticum durum Desf.) is constrained by its large genome and allopolyploid nature. We developed a Diversity Arrays Technology (DArT) platform for durum wheat to enable efficient and cost-effective mapping and molecular breeding applications. Genomic representations from 56 durum accessions were used to assemble a DArT genotyping microarray.
In this paper we focus on two technologies that appear to be suited for whole-genome profiling: SNP and DArT. Sequencing accomplishments in several model species have shown that the value of sequencing is limited without comprehensive information about genome diversity.
