本文采用灰色系统理论对水稻稳定株系的诸多性状因子进行综合评价和定量分析。分析结果表明：①将诸多的性状因子融为一体，在理想的标准品种模式高选择压力下进行测评，避免了优良材料的丢失和淘汰。②依据灰色关联度的排序，吉96-2146名列第一，吉96-2798名列第二，吉96-2572名列第三。
In this paper, the gray system theory of rice stable strains of many trait factors for comprehensive evaluation and quantitative analysis. The results of the analysis show that: (1) The traits of many traits are integrated and evaluated under the high selection pressure of ideal standard varieties, which avoids the loss and elimination of excellent materials. ② According to the gray relational rank, Ji 96-2146 ranked first, Ji 96-2798 ranked second, Ji 96-2572 ranked third.
