Abstract

The determination of genetic relatedness among elite materials of crop species allows for more efficient management of breeding programs and for the protection of breeders' rights. Seventy simple sequence repeats (SSRs) and 234 amplified fragment length polymorphisms (AFLPs) were used to profile a collection of 58 durum wheat (Triticum durum Desf.) accessions, representing the most important extant breeding programs. In addition, 42 phenotypic traits, including the morphological characteristics recommended for the official distinctness, uniformity, and stability tests, were recorded. The correlation between the genetic similarities obtained with the 2 marker classes was high (r = 0.81), whereas lower values were observed between molecular and phenotypic data (r = 0.46 and 0.56 for AFLPs and SSRs, respectively). Morphological data, even if sampled in high numbers, largely failed to describe the pattern of genetic similarity, according to known pedigree data and the indications provided by molecular markers.
