摘　　要：在小麦(TriticumaestivumL.)品质遗传改良中,分别建立了细胞(或个体)、蛋白质和DNA水平的综合标记辅助选择体系,在育种实践中可快速、准确地从杂交后代选育优质面包小麦、优质面条小麦和糯性小麦。The integrated marker-assisted selection system in cell or individual, protein and DNA levels was established for breeding bread-making wheat , noodle-making wheat and waxy wheat. Their lines with good quality characters were obtained by conventional hybridization breeding method in combination with individual selection, SDS-PAGE, STS and SSR markers. And application of the integrated marker-assisted selection system was also discussed.
