摘　　要：应用灰色系统理论中的关联度分析方法,对我课题组2002年水稻新品系比较试验的结果进行综合评估,结果与品系实际表现基本一致。证明由于各性状对品系的重要性不同,在给出不同的权重系数时,运用灰色关联分析对水稻新品系进行多性状综合评估比单纯依靠产量结果对参试品系进行评估更具科学性。品6加权关联度最大,明年可参加省区试。Applying contingency degree to analyz e and estimate the experimental compare the rice strains in2000shows the resu lt is basically in accordance with actual express.Becauise of the different im portance of various characters to strains applying the analyze of gray contingen cy to estimate character of new rice strain is more science than only desponding on the yield result when different weight coefficients were given.The strain six is of maximum contingency degree that will be practiced in province next ye ar.
