Title: Analysis of genetic relationships of cultivars in Pennisetum by RAPD markers
Abstract: The genetic relationships of eight cultivars and lines in Pennisetum. were analyzed using random amplified polymorphic DNA (RAPD) markers. A total of 169 reproducible RAPD fragments were produced using 19 random primers. One hundred and eleven fragments (65.7% of the total observed) were polymorphic, which indicated that there was high genetic diversity among these eight genotypes. From the results of UPGMA cluster analysis, ‘Huanan’, ‘New line’ , ‘Mott’, ‘N (51)’, ‘Reyan NO.4’ and ‘Guimu NO.1’ formed a pedigree group, which was strongly supported by bootstrap analysis. There was also genetic differentiation between the ‘Hybrid pennisetum’ and the other seven genotypes. In addition, the ‘New line’ of elephantgrass was most similar to ‘Mott’ (genetic distance of 0.130), compared with other six cultivars.
