DISTANT HYBRIDIZATION

Distant hybridization, which can shatter species boundaries, boost genetic diversity, and blend the biological traits of existing species, refers to crossings between two distinct species, genera, or higher-ranking taxa. It is a crucial method for developing genetic diversity, viable strains, and superior traits in new strains and populations.

DISTANT HYBRIDS AND THEIR VERIFICATION BY MEANS OF RAPD

Acta Horticulturae, 2005
In Poland, apart from Oriental lilies, Lilium longiflorum and its Asiatic hybrids, have become very popular. As a result of interspecific and intergroup hybridization, progeny plants may not always be hybrids. Embryos may be formed via apomixis and such seedlings contain the genetic material of the maternal form.

MOLECULAR MARKERS IN DETECTION OF DISTANT HYBRIDS IN LILIUM

Acta Horticulturae, 2001
Plants were obtained by ovule rescue from pollinations of lily cultivars belonging to the group oriental hybrids with pollen of Lilium henryi, L. pumilum and L. x formolongi. In order to develop molecular DNA markers useful for separation of the hybrids all the parental genotypes, resulting seedlings and regenerants were fingerprinted using RAPDs.

Distant Hybrids from Parents with Reduced Immunological Reactivity

Nature, 1958
IF they hatch out at all, there is usually a high incidence of malformation in hybrids between guinea fowl hens and domestic fowl cocks1–3. Adult hybrids have been described only twice4,5.

Selection Theory and Procedure in Progenies of Distant Hybrids

1992
In the presence of declining genetic variability among cultivated forms of crop species, breeders’ interest has blossomed over the past two decades in the preservation and introgression of exotic and wild species. Future genetic improvement in crop productivity and quality is potentially constricted by the narrow genetic base from which breeders ...

Distant Hybridization Involving Different In Vitro Techniques

2013
The Brassicaceae family has extensive genetic type and variation, which makes distant hybridization to be a potential strategy for integrating important traits such as quality and resistance to diseases and/or pests into the cultivated species from wild species.

Lower‐hybrid‐drift wave turbulence in the distant magnetotail

Journal of Geophysical Research: Space Physics, 1978
Recent satellite observations of electrostatic and magnetic noise in the distant magnetotail (Gurnett et al., 1976) can be explained by the excitation of the lower‐hybrid‐drift instability. In particular, it is shown that (1) existence conditions for the lower‐hybrid‐drift instability can be met, (2) the observed frequency spectra and polarization are ...

Distant Hybridization: A Tool for Interspecific Manipulation of Chromosomes

2013
Wide or distant hybridization has been widely used as an important tool of chromosome manipulation for crop improvement. The chromosome behaviors in F1 hybrids provide us with the essential genetic basis for chromosome manipulation. The induction of homoeologous pairing in F1 hybrid plants followed by the incorporation of a single-chromosome fragment ...

Molecular Biology/Genetic Transformation in Distant Hybridization

1992
No plant breeding accomplishment has had more impact on agricultural production than the transfer of genes from closely related species, especially in the ornamentals. A high proportion of most perennial herbs and shrubs are hybrid in origin. Wide crosses, including intergeneric hybrids, have been frequent in ornamentals, especially among roses ...
