摘要
Abstract
A molecular genetic map of Chinese cabbage was constructed with a 102 recombinant inbred(RI) population from a cross of two cultivated Chinese cabbage lines 177 and 276, using AFLP and RAPDmarkers. 352 markers including 265 AFLP markers and 87 RAPD markers were integrated into 17 linkagegroups. It covered a total of 2 665.7 cM with an average interval of 7.6 cM. AFLP marker is efficient formap construction while it easily forms clusters to cause big gaps in map. A total of 13. 92% abnormal segrega-tion markers distributed in the map. The molecular genetic map is fundamental for gene localization, compar-ative genomics, and QTL mapping of important agronomic traits.关键词
