Gamma radiation induced a series of structural aberrations involving Thinopyrum bessarabicum chromosome 4J. The aberrations allowed for deletion mapping of 101 4J-specific markers and fine mapping of blue-grained gene BaThb. Irradiation can induce translocations and deletions to assist physically locating genes and markers on chromosomes. In this study, a(More)
Blue wheat grain contains different groups of pigments that can be used for making specialty foods or as food colorants. Thinopyrum bessarabicum, a wild relative of wheat, carries a blue-grained gene on chromosome 4J. In this study, we analyzed the mitotic chromosomes of 159 F7 lines derived from the cross between Triticum aestivum cv. Chinese Spring (CS)(More)
Multiple structural aberrations produced by chromosome breakage and reunion not only provide new germplasm for enriching genetic diversity but are also helpful for physical mapping of alien chromosomes introgressed into wheat. In this study, mass structural aberrations of rye chromosome 2R were induced by means of spontaneous breakage and reunion,(More)
