摘要: DNA restriction fragment length polymorphism (RFLP) analysis was performed on 50 wild and old cultivated sugarcane accessions. Ninety-four maize low copy nuclear DNA sequences of known chromosomal position were screened for hybridization to digested sugarcane genomic DNA blots. Seventy-five (80%) gave very strong hybridization signals and usually yielded many bands and detected profuse polymorphism. Twenty-nine probes and 36 probe/enzyme combinations were selected on the basis of the scorability of the …
