Comprehensive evaluation of drought resistance of twelve alfalfa accessions at seedling stage

The article reported the response of twelve alfalfa(Medicago sativa) germlasms under three soil water conditions (control,moderate and severe drought stress) with pot experiment in room.The subordinative function of the standard deviation coefficient given weighting was utilized to comprehensive evaluation of the alfalfa germlasms drought resistance.The results showed that the drought resistance of the twelve alfalfa germlasms followed this order: Medicago sativa cv.Hetian DayeM.sativa cv.AohanM.ovaria.cv.AletaiM.sativa cv.Gannong No.3M.sativa(Qitai)M.sativa(Bazhou)M.sativa (Shawan)M.sativa(Fukang)M.sativa cv.BeijiangM.sativa(Buerjin)M.sativa(Cele)M.sativa(Yili).This research provided the theoretical basis for drought-resistant alfalfa breeding in Xinjiang.
