摘　　要：应用灰色系统理论中的杂交组合灰色评判原理和方法,对16个甘蔗细茎野生种远缘杂交组合进行综合评判。结果表明:N2、N4、N7、N12、N16五个组合为优良组合(一等),在以后的各世代中应集中精力重点选择;N1、N8、N10、N11、N14五个组合为较好组合(二等),其综合性状稍差于优良组合,应进一步观察试验;N3、N5、N6、N9、N13、N15六个组合为一般组合(三等),在没有特殊优异性状表现的情况下,应考虑淘汰。The comprehensive evaluation for 16 distant crossing combinations of sugarcane was analyzed by grey evaluation theory. The results showed that the 5 best combinations as the first class were N2, N4, N7, N12 and N16, they should be especially elected to breed through per progenitive generation;5 better combinations as the second class were N1, N8, N10, Nil and N14, they were inferior to the best combinations in integrated characteristics and should be observed and tested; 6 ordinary combinations as the third class were N3, N5, N6, N9, N13 and N15, they would be not used except special characters.
