It is speculated that introgression has occurred several times in RC cattle with Bos indicus and Bos taurus cattle in the recent millennia because there was no existence of taurine cattle population in Bangladesh before 20th century.
Also, they found two wild populations in SEYUC with wild-domesticated introgression characteristics (Table 2).
Further investigation using remaining monosomic stocks, in conjunction with DNA marker genotyping, might reveal the location of the alternate introgression event.
To verify the introgression of perennial teosinte chromosome segments into MZI202, maize genomic DNA was digoxigenin labeled and its signals were detected with FITC.
Introgression thus refers to "the infiltration of germplasm from one species into another through repeated backcrossing of the hybrids to the parental species" (Anderson and Hubricht, 1938; Arnold 1997).
In these genotypes, many of the initial introgressions of tepary genes have now been used in multiple generations of crosses, backcrosses, and recurrent selection with common bean and the resulting genotypes present very few phenotypic characteristics of tepary beans.
Although the 1RS introgressions have conferred broad adaptation, high yields, and yield stability, they have frequently demonstrated unsatisfactory end-use quality, especially diminished mixing tolerance, dough stickiness, reduced loaf volume, and poor crumb grain when compared with wheats with a standard chromosome constitution (Dhaliwal et al.
Evaluation of near-isogenic lines carrying single-donor introgressions for desirable wild QTL-alleles derived from Lycopersicon hirsutum and L.
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.
Introgressions 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).
