Parental and consensus maps were constructed in an
F2 inter-provenance cross of Eucalyptus globulus, using
amplified fragment length polymorphism (AFLP) and
microsatellite (or simple sequence repeats [SSR]) markers.
The female map had 12 linkage groups and 118
markers, comprising 33 SSR and 85 AFLP loci. The
male map had 14 linkage groups and 130 markers comprising
36 SSR and 94 AFLP loci. The integrated map
featured 10 linkage groups and 165 markers, including
33 SSR and 132 AFLP loci, a small 11th group was identified
in the male parent. Moderate segregation distortion
was detected, concentrated in gender specific
groups. The strongest distortion was detected in the
female parent for which causal mechanisms are discussed.
The inclusion of SSR markers previously
mapped in several different eucalypt species within the
subgenus Symphyomyrtus (E. globulus, E. camaldulensis,
and predominantly E. grandis and E. urophylla),
allowed comparison of linkage groups across species and
demonstrated that linkage orders previously reported in
E. globulus, E. grandis and E. urophylla were largely
