TI  - Molecular cytogenetic identification of a novel dwarf wheat line with 
      introgressed Thinopyrum ponticum chromatin.
PG  - 149-55
AB  - Novel dwarfing germplasms and dwarfing genes are valuable for the wheat breeding. 
      A novel semi-dwarf line, 31505-1, with reduced height compared with its common 
      wheat parent, was derived from a cross between common wheat and Thinopyrum 
      ponticum. Cytological studies demonstrated that 31505-1 contained 42 chromosomes 
      and formed 21 bivalents at meiotic metaphase I. Genomic in situ hybridization 
      (GISH) analysis showed that 31505-1 had no large Th. ponticum chromosome 
      fragments. Fluorescence in situ hybridization (FISH) results revealed the absence 
      of a pAs1 hybridization band on 2DL chromosome of 31505-1. Two SSR markers 
      (Xwmc41 and Xcfd168) and two STS markers (Xmag4059 and Xmag3596), which were 
      located on 2D chromosome, amplified unique bands of Th. Ponticum in 31505-1. 
      These revealed presence of an introgressed Th. ponticum segment in 2DL chromosome 
      of dwarf line 31505-1, although the alien segment could not be detected by GISH.
