The Salix alba L. (white willow)—Salix fragilis L. (crack willow) complex includes closely related polyploid species, mainly tetraploid (2n = 4x = 76), which are dioecious and hence obligate allogamous. Because little is known about the genome constitution and chromosome behavior of these pure willow trees, genetic analysis of their naturally occurring interspecific polyploid hybrids is still very difficult. A two-way pseudo-testcross strategy was exploited using single-dose AFLP markers in… CONTINUE READING

In conclusion , half of the chromosomes of the pure species S. alba and S. fragilis are closely related and they could share a common diploid ancestor , while the rest of chromosomes are morphologically differentiated in either S. alba or S. fragilis and they should derive from distinct diploid ancestors .

In addition , a genomic in situ hybridization ( GISH ) technology was implemented in willow to shed some light on the genome structure of S. alba and S. fragilis species , and their hybrids ( allopolyploidy vs. autopolyploidy ) .
