It takes many, many years of
backcrossing to combine the best of both worlds," he said.
Minimum sample size and optimal positioning of flanking markers in marker-assisted
backcrossing for transfer of a target gene.
Looking to give a small portion of that ability to sorghum, Paterson used
backcrossing, a traditional breeding process that repeatedly introduces a desired trait into a cross between two plants.
In this study, we aimed to introgress a blast resistance gene using local resistant genotypes, Pongsu Seribu 2 into MR264, a high-yielding rice variety that is blast susceptible thru Marker-Assisted
Backcrossing (MABC) approach.
Restoration of genetic background: Hospital 2003 used ratio ofhomozygous markers(two allelesbothfrom recipient) to all markers to show restoration of recipient genetic background, unlike Hospital, we used percentage of alleles inherited from the recipient parent to estimate restoration of recipient genetic background, the restoration status of recipient genetic background under different background selection methods show in figure 2:
backcrossing two generations, the restoration degree of recipient genetic background reached 93% by genomic similarity selection and index selection,
backcrossing four generations, restoration degree of recipient genetic background reached 100%.
The relations of family relationships and hierarchical structuring were established considering genetically divergent parent populations, F1 hybrids and five generations of
backcrossing in relation to each of the parents, thereby establishing parameters of effectiveness of the assessed methodologies.
mollissima) into an American chestnut hybrid--one that maintained the important American chestnut characteristics through progressive generations of
backcrossing (Hebard 2014).
ABSTRACT The growth characteristics and morphological features of the Atlantic bay scallop (Argopecten irradians irradians Lamarck), Chilean scallop (Argopecten purpuratus Lamarck), F1 hybrids of these species, and the offspring produced via 2 cycles of
backcrossing between hybrid populations and the Atlantic bay scallop were examined to determine the feasibility of broadening the genetic basis of the bay scallop.
This finding is further supported by a more recent and reliable molecular/genetic study showing a low frequency of
backcrossing in common carp X goldfish hybrids (Hanfling et al.
Upper grades study forest ecology, perform DNA experiments, and study the genetics of
backcrossing Chinese chestnut hybrids to surviving native chestnuts, aiming for a tree that incorporates the desirable characteristics of the native with just enough Chinese to resist blight.
We know that a species evolves in the wild by crossing and
backcrossing over several centuries until you get a fairly stable population.
Through
backcrossing, the researchers have produced progeny that also offer good productivity, vigor and adaptation.
