中文摘要：
本研究在广泛的野外调查和材料收集的基础上，通过对拟鹅观草属Pseudoroegneria植物进行形态特征和地理分布分析、属间和种间杂交及繁育资料、细胞学和细胞遗传学、基因组原位杂交（GISH）技术、分子生物学等手段，研究拟鹅观草属特别是四倍体物种的染色体组成；确立拟鹅观草属、Douglasdeweya和Trichopyrum属的系统地位；分析拟鹅观草属与Douglasdeweya和Trichopyrum等属的属间关系、属内种间关系和种下等级及其变异式样；探讨独特的地理分布式样；进行分类处理和修订。同时，系统整理国产拟鹅观草属植物，提出拟鹅观草属的分类系统。拟解决拟鹅观草属的系统地位、物种分类处理疑问，为客观认识拟鹅观草属的起源和演化，小麦族披碱草属、偃麦草属、鹅观草属、仲彬草属、猬草属、裂颖草属等具有St染色体组的多年生多倍体属的起源和系统进化，以及高等植物的杂交和进化提供资料。
