RAPD技术在稻米品质鉴定中的应用研究

Application of RAPD Technique to the Identification of Rice-quality

采用RAPD技术对两组不同米质水平的水稻品种进行鉴定,结果表明：20个引物中有4个呈现扩增多态性,扩增率为20％;优质与劣质稻米品种在分子水平上存在差异.

Rice varieties of two groups of different rice-quality were identitied by using RAPD technique . It showed that four of 20 primers were emerged in amplified pclysmorphism; the rate of amplification was 20 percent. From this the difference of melecule between high-quality and low-quality eating rice was proved.
