The i-esults conflrmed 3 translocation, 3 telosome 4 isochromosome and one dicentric chromosome lines involving 4V. Meanwhile, two chromosome rearrangements were aslo observed within wheat species. 11 Creation of Eaesiiln. vi/iosa 6V translocation hues via gc nC1)hlb In BC F generation, i.e (C.S.ph I bph lb X Sub6V)F X CS. phi bph I b, some plants with high homoeologous chromosonie pairinu frequency were lbund by PMC chromosome airing configuration analysis at Ml stage. A 6VS translocation line, ZS4S, were identified in BCF. by chromosome C-banding, PMC Ml analysis and FiST analysis. This line showed powdery mildew resistance indicating the presence of gene Pm2l.
