HE Yu-tang 1,2 , TU Jin-xing 1, FU Ting-dong 1, LI Dian-rong 2, CHEN Bao-yuan 1 ( 1. National Key Laboratory of Crop Genetic Improvement, Huazhong Agricultural University, Sub-Center of National Rapeseed Improvement, Wuhan 430070, China; 2.  
The UPGMA method was appled to cluster and analyze 15 characters of 199 landraces of B.campestris germplasm from Shanxi province with morphological markers. The left 29 varieties through eliminating unwanted entries were analyzed by UPGMA and RAPD markers. The dendrograms of B.campestris by RAPD and morphological markers were compared, and the core germplasm including 28 varieties of B.campestris from Shanxi province was preliminarily assembled. The results showed that genetic variation revealed by morphological markers was not always consistent with revealed by RAPD markers to a certain degree. It was an effective method to develop a core collection of the crop by RAPD markers and morphological markers.
