1The construction of a genetic linkage map of non-heading Chinese cabbage (Brassica campestris ssp.chinensis Makino)显示文摘Non-heading Chinese cabbage(Brassica campestris ssp.chinensis Makino) is one of the most important vegetables in eastern China.A genetic linkage map was constructed using 127 doubled haploid(DH) lines,and the DH population was derived from a commercial hybrid 'Hanxiao'(lines SW-13 × L-118).Out of the 614 polymorphic markers,43.49% were not assigned to any of the linkage groups(LGs).Chi-square tests showed that 42.67% markers were distorted from expected Mendelian segregation ratios,and the direction of distorted segregation was mainly toward the paternal parent L-118.After sequentially removing the markers that had an interval distance smaller than 1 cM from the upper marker,the overall quality of the linkage map was increased.Two hundred and sixty-eight molecular markers were mapped into 10 LGs,which were anchored to the corresponding chromosome of the B.rapa reference map based on common simple sequence repeat(SSR) markers.The map covers 973.38 cM of the genome and the average interval distance between markers was 3.63 cM.The number of markers on each LG ranged from 18(R08) to 64(R07),with an average interval distance within a single LG from 1.70 cM(R07) to 6.71 cM(R06).Among these mapped markers,169 were sequence-related amplified polymorphism(SRAP) mo-lecular markers,50 were SSR markers and 49 were random amplification polymorphic DNA(RAPD) markers.With further saturation to the LG,the current map offers a genetic tool for loci analysis for important agronomic traits.Yan Cheng Jianfeng Geng Jingyi Zhang Qian Wang Qingyu Ban Xilin Hou 2009Journal of Genetics and Genomics2009,36,8:9
