摘  要：
为筛选出适宜在西辽河平原推广利用的优质糯高粱种质资源,对176份糯高粱种质资源的16个主要农艺性状进行分析,并采用主成分分析法、灰色关联度法和DTOPSIS法3种分析方法相结合进行综合评价.结果表明,176份糯高粱种质资源主要农艺性状的变异系数介于6.69%~47.84%,各性状指标间总体上存在显著或极显著相关性.通过主成分分析,将176份糯高粱种质资源的16个主要农艺性状综合成为了 9个相互独立的综合指标(主成分),这9个主成分的累计贡献率达87.169%.基于主成分分析法求出的综合评价得分、根据灰色关联度法求出的加权关联度、根据DTOPSIS法求出的相对贴近度分别筛选出排名前30的种质资源,并结合这3种方法进行综合评价,从176份参试种质资源中选出了 10份综合性状优良的种质资源,分别为QNR、9705、2011-30、忻粱52、102A、护脖矬P4、Jan-88、9701、0657、4126,为西辽河平原地区糯高粱品种选育奠定了基础.

摘  要：
In order to screen out the high-quality waxy sorghum germplasm resources suitable for popularization and utilization in the Xiliaohe Plain,16 main agronomic traits of 176 waxy sorghum germplasm resources were analyzed,and the comprehensive evaluation and ranking were carried out by combining principal component analysis method,grey correlation degree method and DTOPSIS method.The results showed that the coefficient of variation of the main agronomic traits of 176 waxy sorghum germplasm resources ranged from 6. 69% to 47. 84%,and there were generally significant or extremely significant correlation between the traits. Through principal component analysis,16 main agronomic traits of 176 waxy sorghum germplasm resources were integrated into 9 independent comprehensive indexes(principal components),and the cumulative contribution rate of these 9 principal components was87. 169%. The top 30 germplasm resources were screened based on comprehensive evaluation scores by principal component analysis,weighted correlation degree by grey correlation degree method and relative closeness degree by DTOPSIS method respectively. By the combination of the above three methods for comprehensive evaluation,10 germplasm resources with excellent comprehensive traits were selected from 176 germplasm resources,namely QNR,9705,2011-30,Xinliang 52,102A,HubocuoP4,Jan-88,9701,0657 and 4126,respectively,which laid a foundation for the breeding of waxy sorghum varieties in the Xiliaohe Plain.
