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 …

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 …

Polyploid breeding is one of the most important approaches to improve the traits of cultivated
plants, but there has been no feasible method to get polyploid tree peony. In this study, we …

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 …

This paper analyzed the karyotypes of 4 species of triploid poplar. The results were as
follows: Populus tomentosa, 2n= 3x= 57= 1 M+ 31 m+ 10 sm+ 15 st; P.× euramericana cv.'I …
