摘 要 ：玉米淀粉修饰基因du是玉米品质改良的重要资源之一。本研究运用RAPD技术，以4种不同遗传背景的近等基因系(A632 Du/Du, A632 du/du; Mo17 Du/Du, Mo17 du/du; Oh43 Du/Du,Oh43 du/du; W64 Du/Du, W64 du/du)为筛选材料，采用(7922 Du/DuXMo17 du/du)和(HZ32 Du/Du XMo17 du/du)F:群体，研究du基因的分子标记。两个群体分别

Abstract:Starch-modified gene du is one of important genetic resources in starch genetic modifi-cation for maize. The objective of the research was to find molecular markers linking with du gene by RAPD. A total of 356 random primers were screened with 4 iso-genic lines (A632 Du/Du，A632 du/du;Mo17 Du/Du，Mo
