Abstract

The drought resistance of ten alfalfa germplasm resources was evaluated by principal components analysis and subordinate function analysis.Results show that the 17 significantly different drought-resistance indexes could be classified into 4 component parts: biomass factor,plant morphological factor,root factor,and stress index factor.The capacity of drought resistance of the ten alfalfa germplasm resources is gauged as follows: LongdongBL-02-388AohanBL-2-312BL-02-344Gongnong NO 1Zhongmu NO 1BL-02-353Xinjiang DayeBL-02-329.
