摘要
用灰色系统理论中关联度分析的基本原理和方法,对15个萝卜杂交组合10个主要农艺性状进行了综合描述,较为全面、客观地评价了参试组合的优劣。结果表明:在等权关联度排序和加权关联度排序相比的结果来看,加权关联度排序更能反映品种的多个农艺性状的实际表现;X12,X13,X14和X5加权关联度排序上均居于首要位置,农艺性状表现突出。
Through the grey relational analysis of the grey system the theory,10 important agronomic characters of hybrids were comprehensive evaluation ,the qualities of hybrids were objectively graded. The results showed： comparing with the order of equweighted grey relevant degree and weighted grey relevant degree, the order of weighted grey relevant degree could more accurately reflect many agronomic characters of hybrids. X12,X13 ,X14 and X5 are in the first situation in the order of weighted grey relevant degree, they have great agronomic characters.
