英文摘要 | With Brassica olercea var. alboglabra as an outgroup, twelve accessions of broccoli (Brassica oleracea L. var. botrytis L.) and cauliflower (B. oleracea L. var. italica ) (including F�� hybrids and their parents) are analyzed using random amplified polymorphic DNA (RAPD) markers. Ninety five DNA markers are generated by nine oligonucleotide primers, two are specific for Brassica oleracea var. alboglabra, eight are accession specific, seventeen are monomorphic for both cauliflower and broccoli, three are monomorphic for broccoli, and sixty five are polymorphic for both broccoli and cauliflower. Using UPGMA analysis, twelve accessions can be divided into two groups with one belonging to cauliflower and the other to broccoli. The result of phylogenetic relationship is clearly correlated to morphological difference. However, one accession of broccoli is shown to have greater genetic distance to other accessions of broccoli than to some accessions of cauliflower. |
