This paper focuses on Bromus inermis which chosen from 12 regions at home and abroad to analyze theirs drought resistance and genetic diversity. The drought resistance research was divided into two stages:seed germination and seedling growth. Study on the drought-resistance used by PEG-6000 to simulated drought stress environments at seed germination stage and continuous drought at seedlings stage, and genetic diversity took random amplified polymorphic DNA (RAPD). The main results are as follows:
