摘 要 ：通过对33份09系列甘蔗属原种间杂交F1代的灰色接近度分析，结果表明：排位在前10名的是09-162、09-167、09-164、09-172、09-167-1、09-174、09-167-2、09-161、09-179、09-166，有19份材料超过对照ROC22和粤糖93-159，其结果与试验观察结果相符；灰色接近度分析与同一度分析结果一致，与灰色关联度分析总体一致，说明灰色接近度分析是一种简便、有效的方法之一。

Abstract:New thirty-three hybrid F1 of the Sacchrum species were evaluated by the grey closeness degree. The results showed that the order of the frontal ten was 09-162、09-167、09-164、09-172,09-167-1,09-174,09-167-2,09-161,09-179 and 09-166. There are nineteen materials exceeding ROC22 and YT93-159.Thise is accord to the trial observing. The result of the grey closeness degree analysis is completely same to the identical degree analysis , and basically same to gray correlation degree . The grey closeness degree analysis is a good method.
