The molecular karyotype could represent the basic genetic make-up in a cell nucleus of an
organism or species. A doubled haploid (DH) is a genotype formed from the chromosome …

Poplar was one of the first woody species whose individual chromosomes could be
identified using chromosome specific painting probes. Nevertheless, high-resolution …

Background Interspecies hybridization is widely used to achieve heterosis or hybrid vigor,
which has been observed and harnessed by breeders for centuries. Natural allopolyploid …

The karyotypes analysed were obtained from kidney cells of five marine fishes by means of
injection of colchicine, hypotonic treatment and air-dry technique. The karyotype of Liza …

In this paper, comparative studies on karyotype and C-banding of varieties of Paeonia rockii
and those of P. suffruticosa have been first reported. Ten materials were used in karyotype …

Interploidy cross commonly results in complex chromosome number and structural
variations. In our previous study, a progeny with segregated ploidy levels was produced by …

Chromosomal landmarks in four Pinus species: P. densiflora, P. thunbergii, P. sylvestris, and
P. nigra were identified by fluorescence in situ hybridization (FISH) using hapten-or …

Itoh hybrids are intersectional hybrids in Paeonia L. with sect. Moutan and sect. Paeonia as
paternal and maternal parents, respectively. Therefore, these hybrids have herbaceous …

The karyotypes of 9 species/varieties of section Populus in the genus Populus was analysed
for the first time. The following results were recorded: P. alba, 2n= 28= 1 M+ 30 m+ 4 sm …
