DArT (Diversity Array Technology) markers assessed in a large set of olive cultivars have been used to evaluate their utility for the management of the World Olive Germplasm Bank (WOGB-Córdoba) of IFAPA Centre “Alameda del Obispo” Córdoba (Spain).
Hordeum chilense, a native South American diploid wild barley, is one of the species of the genusHordeum with a high potential for cereal breeding purposes, given its high crossability with other members of the Triticeae tribe. Hexaploid tritordeum (×Tritordeum Ascherson et Graebner, 2n=6×=42, AABBHchHch) is the fertile amphiploid obtained after chromosome doubling of hybrids between Hordeum chilense and durum wheat
The present study reports the setting up of Diversity Arrays Technology (DArT) markers in olive (Olea europaea L.). Two genomic representations were generated using the PstI/. TaqI combination. A first one was aimed to cover the variability available at the World Olive Germplasm Bank (WOGB) and it was based on DNA from 87 olive cultivars carefully selected from the WOGB to represent the olive variability.
The transfer of genes between Triticum aestivum (hexaploid bread wheat) and T. turgidum (tetraploid durum wheat) holds considerable potential for genetic improvement of both these closely related species. Five different T. aestivum/T. turgidum ssp. durum crosses were investigated using Diversity Arrays Technology (DArT) markers to determine the inheritance of parental A, B and D genome material in subsequent generations derived from these crosses
