These
Backcross 2 progenies possess 87.5% of their genome coming from abaca.
Introgressing gressing multiple QTL in
backcross breeding programs of limited size.
Advanced
backcross QTL analysis: A method for the simultaneous discovery and transfer of valuable QTLs from unadaptedgermplasm into elite breeding lines.
During
backcross phase, selected individuals of which two markers are both heterozygosity, during intercrossing phase, selected individuals of which two markers are both homozygosity or heterozygosity.
Therefore, to accomplish its mission, the
backcross method utilized by TACF gradually builds the proportion of American to Chinese genes to the point that hybrids have obtained at least 15/16 (~94%) of genetic makeup from a C.
The universal feminization observed in mature F 1 hybrids or F2
backcross hybrids made it more convenient for us to obtain pure eggs of hybrids using the same spawning methods described earlier.
However, if
backcrosses between hybrids and parental stocks do occur in the field, attempts to separate hybrids and their progeny from the parent species would be complicated because hybrid identification using standard morphometric and meristic measurements depends on the occurrence of intermediate traits (Gilbert, 1961).
The offspring and their descendants were
backcrossed to purebred Dalmatians for many generations, resulting in dogs that are indistinguishable from purebred Dalmatians.
Identification of QTLs for early blight (Alternaria solani) resistance in tomato using
backcross populations of a Lycopersicon esculentum x L.
In this study, parental, F1, F2, and
backcross populations were used: 1) to quantify maternal inheritance, degree of dominance, and transgressive segregation; and 2) to determine whether CI 13227 and L-574-1 share any resistance genes.
