摘要: DNA amplification fingerprinting (DAF) using a high primer-to-template ratio and single, very short arbitrary primers, was used to generate amplified fragment length polymorphic markers (AFLP) in soybean (Glycine max (L.) Merr.). The inheritance of AFLPs studied cross between the ancestral Glycine soja PI468.397 Merr. line nts382, F1 F2 progeny. reaction carried out with genomic 8 base long oligounucleotide primers. Silver-stained 5% polyacrylamide gels containing 7 M urea detected from 11 28 DAF products primers varying GC content (ranging 50 100% GC). Depending on their intensity, were classified into three classes. profiles reproducible for different extractions gels. Forty by 26 when comparing G. max. Most inherited as dominant Mendelian populations. However, abnormal occured about 25% polymorphisms. One marker maternal marker, presumably originating organelle while another showed apparent paternal inheritance. To confirm nuclear origin utility markers, polymorphisms mapped F11 mapping population recombinant inbred lines cultivars Minsoy × Noir 1. study that DAF-generated occur frequently reliably, they are loci can be genome mapping.
