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。
Based on the gray evaluation theory and method of hybrid combination in gray system theory, comprehensive evaluation was made on the distant hybridization combinations of 16 stems of wild stems of sugarcane. The results showed that the five combinations of N2, N4, N7, N12 and N16 are excellent combinations (first class), and should be focused on the following generations; the five combinations of N1, N8, N10, N11 and N14 are better Combination (second), the composite trait is slightly worse than the excellent combination, should further observe the experiment; N3, N5, N6, N9, N13, N15 six combinations for the general combination (third), in the absence of special excellent traits Under, should be considered eliminated.
