| 中文摘要 | alien chromosomes of twelve giant spike wheat germplasm lines were identified by c-banding, genomic in situ hybridization (gish), sequence characterized amplified region (scar), and random amplified polymorphic dna (rapd). all lines showed a chromosome number of 2n = 42, five of them carried both a pair of wheat-rye (triticum aestivum-secale cereal) 1bl/1rs translocation chromosomes and a pair of agropyron intermedium (ai) chromosomes, three carried a pair of ai chromosomes only, three others carried a pair of 1bl/1rs chromosomes only, and one carried neither 1bl/1bs nor ai chromosome. further identification revealed that the identical ai chromosome in these germplasm lines substituted the chromosome 2d of common wheat (triticum aestivum l.), designated as 2ai. the genetic implication and further utilization of 2ai in wheat improvement were also discussed. |
