Polyploidy has played a major role in higher plant evolution. Most flowering plants are
polyploid, and many are distinct in combining the diploid nuclear genomes from two or more …

Publisher Summary This chapter provides a discussion of recent advancements, in context
to plant polyploidy. Polyploidy plays a very important role in plant evolution. Major recent …

During the past decade, molecular techniques have provided a wealth of data that have
facilitated the resolution of several controversial questions in polyploid evolution. Herein we …

Polyploidy played a significant role in the origin and evolution of many plant species. The
primary phylogenetic effect of polyploidy is to stabilize selected hybrid genotypes. It also …

Polyploidy, the condition of possessing more than 2 complete chromosome sets in the same
nucleus, is frequent in nature and has implications for a species' prospects for evolution …

Polyploidy is a conspicuous feature of chromosomal evolution in higher plants. Stebbins (1)
estimates that between 30 and 35 percent of flowering plant species have gametic …

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 …

It is well known that polyploidy is a major force in evolution, particularly in plants. Perhaps
50% of all angiosperms are of polyploid origin; estimates for the ferns and fern allies range …

Several different estimates of polyploid frequency in angio-sperms have been made,
including GL Stebbins'(1, 2) figure, first published in 1950, of 30–35%, and suggestions by …

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 …
