By phenotype observation, combined with root tipchromosome counting, PMC MI pairing analysis and chromosome C-banding, a ditelosomic addition line 94K227 and a disomic addition line 94K280 was identified among BC2F2 and BC2F3 population respectively.C-banding results showed that 94K227 contains 1 pair of long arms in chromosome B, and 94K280 contains 1 pair of chromosome D from R.

用普通小麦-纤毛鹅观草双倍体与普通小麦中国春连续回交两次，然后连续自交，通过形态观察、根尖细胞染色体计数、花粉母细胞减数分裂中期Ⅰ染色体配对分析及染色体C－分带，在BC2F3和BC2F3群体中，分别筛选到一个端二体异附加系94K227和一个二体异附加系94K280，其中C-分带显示94K227添加的是纤毛鹅观草染色体B的一对长臂， 94K280添加的是纤毛鹅观草的一对染色体D。

Other three alien translocation lines referring to chromosome Lr.14 of L.racemosus were also induced via irradiated pollens.After irradiated by gamma raysof 1KR does,the pollens of T.aestivum-L.racemosus Lr.14 disomic addition lineswere used to pollinate wheat varieties"Yangmai No.5"and"Mianyang No.11".M1plants have pairing between wheat chromosomes and Lr.14 ofL.racemosus at PMCMI stage were self-pollinated,and the M2 seeds used to be Giemsa C-banded andfluorescence in situ hybridized.As the result,three alien translocation lines wereobtained and T12 was observed to have distal translocation chromosomes betweenLr.14S and a wheat chromosome segment(TW-Lr.14S·Lr.14L).T13 wasidentified to contain mostly-alien-translocation chromosome(TLr.14L·Lr.14S-W).T14 was proved to contain a translocation between Lr.14L and 6BS,with approximatebreakpoint at 6BS2.2 region, FL0.22 in the short arm of chromosome T6BL.6BS-Lr.14L.
