The results indicate that the improved grey target could meet the invariance of effect samples after nonsingular linear transformation caused by clout distance; the weighted Mahalanobis distance is just the weighted Euclidean distance when there is no correlation among observed indexes, which avoids correlation of decision indexes, influences of different dimension and differences of importance on effect of decisions, and the incompatibility of grey target transformation.

结果表明,改进后的灰靶满足:靶心距对效果样本作非奇异线性变换的不变性;当观测指标间不存在相关性时,加权马氏距离就是加权欧氏距离。避免了决策指标间的相关性、不同量纲和重要性差异对决策效果的影响以及灰靶变换的不相容问题。

The spikes per plant of diploid and tetraploidspecies were higher, but the kernels per spike, 1000 kernels weight and grain yield werelower than those of hexaploid and octoploid species.

Variation of NPE andNYE was higher than other NUE indexes, which indicated that NPE and NYE could beused as indexes for NUE differences in different wheat related species.
