【Abstract】 The amplified DNA fingerprints from RAPD of 8 P.geesteranus strains cultivated in different countries and areas were obtained by modern molecular biological techniques and cluster dendrogram was constructed in terms of the DNA fingerprints in this research. And the agronomical characters of these P. geesteranus strains were analysed in this study too. The results showed that large genetic diversities were found between these strains.更多还原
