This yellow, semi-flint breeding population was developed by Rod Edmondson, Funk Seeds International, Kinston, NC, from VaCBX (Virginia-Corn Belt Exotic breeding population was developed by Clarence Genter, Blacksburg, VA) with introgressions
of four elite non-Stiff Stalk inbred lines.
of alien chromatin into wheat are usually done by X-ray induced translocations, whole arm translocations resulting from misdivision-fusion of univalents, or by induced homoeologous recombination (Knott, 1987).
Additionally, the linkage disequilibrium associated with recent introgressions
can be effectively exploited to track specific alleles.
The very weak phylogeographic structure and low genetic differentiation could be a result of a recent common ancestral origin, multiple introgressions
and strong genetic exchange among the indigenous cattle populations [6, 13, 25].
lines for the third chromosome were previously created  by repeated backcrossing of [F.sub.1] hybrids to their parent species and then by several generations of brother-sister mating, paired with molecular genotyping at every generation, to make the introgressions
lunatus to prevent wild-domesticate introgressions
. However, it is possible that several of these wild populations had contact with domesticated populations of Lima bean in the past because of the migratory characteristics of the milpa.
Furthermore, it is assumed that introgressions
have occurred in this breed mainly from Indian zebu breeds in the recent millennia.
The size and number of introgressions
were also determined using GGT software.
of the N gene may also have been achieved by other workers, although information on the derivation and existence of this material is fragmentary (Ternovsky, 1941,1945; Goodspeed, 1942; Kostoff and Georgieva, 1944; Kostoff, 1948; Valleau, 1952; Oka, 1961).
The McGISH protocol has been used successfully to detect three whole-chromosome introgressions
Earlier, such artificial introgressions
were mainly restricted to gene transfer between species that were cross compatible (Maan, 1987), as cross incompatibility problems prevented production of viable seeds among hybrids between unrelated species.
