Accumulated evidence has shown that each of the three basic Brassica genomes (A, B and
C) has undergone profound changes in different species, and has led to the concept of the …

Intensive breeding has led to a narrowing in the genetic base of our major crops. In wheat,
access to the extensive gene pool residing in its many and varied relatives (some cultivated …

In barley (Hordeum vulgare L.), chiasmata (the physical sites of genetic crossovers) are
skewed towards the distal ends of chromosomes, effectively consigning a large proportion of …

The combined use of doubled haploid lines and molecular markers can provide new genetic
information for use in breeding programs. An F 1-derived doubled haploid (DH) population …

Abrupt speciation through interspecific hybridisation is an important mechanism in
angiosperm evolution. Flowering plants therefore offer excellent opportunities for studying …

Background Distant hybridization can result genome duplication and allopolyploid formation
which may play a significant role in the origin and evolution of many plant species. It is …

The Chrysanthemum indicum polyploid complex comprises morphologically differentiated
diploids, tetraploids and hybrids between C. indicum and C. lavandulifolium. The …

Chromosome rearrangements are common, but their dynamics over time, mechanisms of
occurrence and the genomic features that shape their distribution and rate are still poorly …

Intersubgenomic heterosis in rapeseed has been revealed in previous studies by using
traditional Brassica napus (A n A n C n C n) to cross partial new type B. napus with A r/C c …

The large natural variation existing in Brassica oleracea offers a promising approach to
improving B. napus (rapeseed). However, the cytogenetic and genetic characterizations of …
