  • Under different soil-stored water levels,the drought-resistance of 14 dryland winter wheat varieties of different ecological types was researched by means of drought-resistance index,subordinate function values and fuzzy synthetic determination.It is shown that the yield and WUE of dryland winter wheat are improved significantly along with the increasing of soil-stored water before sowing.Under the same soil-stored water level,there is a remarkable difference of the yield and WUE among different varieties.And the reaction to soil-sorted water of different ecological types of winter wheat is different.The drought-resistance of dryland winter wheat can be evaluated excellently by the three methods of drought-resistance index,subordinate function values and fuzzy synthetic determination.The results are basically consistent.Drought-resistance of the tested varieties from different regions appears as East Gansu>Shanxi>Beijing>Weibei Highland>Huanghuai Plain.
