This study detected genetic diversities among upland rice genotypes and between upland rice and rice genotype from molecular level by means of RAPD marker combing field experiment.
本研究结合田间试验，利用RAPD标记从分子水平上探测旱稻品种间的遗传差异、旱稻与水稻间的遗传差异。
The course and rate of the shift of virulence differed from different resistant varieties as a result of their diversities in both resistant mechanism and genetic background.
由于抗虫品种抗虫机制及其遗传背景的差异，褐飞虱在不同的抗虫品种上致害性转化的进程和速率亦不同。
For different genetic locations the results of amplification show diversities which result from mutation and recomposition of genomes, so RAPD can identify genomes.
多态性的产生是由突变或重排造成的，因此RAPD可以用于基因组的特征标记。
