Distribution pattern of seed germination osmotic stress resistance of 80 spring wheat varieties and lines. Note: \( D={\sum}_{j=1}^n\left[U(xj)\frac{\left| rj\right|}{\sum_{j=1}^n\left| rj\right|}\right]j=1 \), 2, 3 (3), D value means the evaluated value of each drought resistance indicator for each species under mannitol stress; 0.8 < D < 1.0 is strong resistance, 0.8 > D > 0.5 is resistance, 0.5 > D > 0.3 is weak resistance, 0.3 > D > 0 is sensitive.
