    Notes: Abstract  We report the development of microsatellites or simple sequence repeats (SSRs) in the olive tree (Olea europaea L.). Forty three positive clones obtained by the screening of a GA-enriched genomic library were sequenced and primers were designed for 13 microsatellite loci. Five primer pairs amplified polymorphic products of the expected size range. SSR polymorphism was explored in a set of 46 olive cultivars. A total of 26 alleles were detected for the five loci. Heterozygosity ranged from 0.46 to 0.71. Ninety one per cent of the cultivars had unique multilocus genotypes. Microsatellite segregation was studied in a complex population from a cross between the commercial cultivars ’Leccino’ and ’Dolce Agogia’.

    Notes: Summary Hordeum chilense is a wild barley with high crossability with Triticum, Hordeum and Secale. Its amphiploid with wheat, tritordeum, has potential as a new crop. H. chilense is highly resistant to the powdery mildew diseases of both wheat and barley. Whereas tritordeum is resistant to barley powdery mildew, its reaction to wheat powdery mildew is similar to that of its wheat parent. However H. chilense contributes to a reduced density of mildew colonies. This quantitative resistance of tritordeum is diluted at higher ploidy levels.

    Notes: Abstract Hordeum chilense exhibits resistance to Septoria tritici. Addition and substitution lines of H. chilensein wheat were utilized in growth chamber and field experiments to determine which H. chilense chromosomes carry resistance genes. Resistance is conferred by gene(s) on chromosome 4 and, to a minor extent, by genes on chromosomes 5, 6 and 7.
