Large gains in the knowledge of plant genetics have been made during the last decade due
to the development and application of DNA markers. The use of DNA markers has allowed …

In 1950, G. Ledyard Stebbins devoted two chapters of his book Variation and Evolution in
Plants (Columbia Univ. Press, New York) to polyploidy, one on occurrence and nature and …

Polyploid organisms carry more than two copies of each chromosome, a condition rarely
tolerated in animals but which occurs relatively frequently in the plant kingdom. One of the …

Most plant species are known to be either ancient or recent polyploids, containing more than
one genome as a result of past interspecific hybridization events (allopolyploidy) and/or …

Statistical methods for genetic mapping have well been developed for diploid species but
are lagging in the more complex polyploids. The genetic mapping of polyploids, where …

Polyploidy is a significant force in plant evolution. Approximately 47% to 52% of all
angiospenn species are polyploid (Y. Grant, 1981). Estimates of the frequency of polyploidy …

Polyploidy is a prominent process in plants and has been significant in the evolutionary
history of vertebrates and other eukaryotes. In plants, interdisciplinary approaches …

Questions regarding species identification, differentiation, and relationships often emerge in
biological investigations. One may need to examine the extent of genetic relationships …

Almost all extant plant species have doubled their genomes at least once in their
evolutionary histories, resulting in polyploidy which provided a rich genomic resource for …

An understanding of nature and extent of nucleotide sequence variation is required for
programmes of discovery and characterization of single nucleotide polymorphisms (SNPs) …
