摘要：[Objective] This study was to screen the economic or stable pcr system of rice and detect the generality of the selected system in different molecular markers based on pcr.[Method] With DNA extracted from rice leaves by CTAB method as the template,pcr system was optimized by L16(45)orthogonal design.[Result] Clear bands were amplified from 16 different combinations,but the amplification effects and yields had *** most economic and applicable system was as follows:20 ng DNA template,150 μmol/L dNT...
