摘要: 【目的】筛选适合内蒙古鄂尔多斯市种植的优质糜子品种,旨在合理利用糜子种质资源。【方法】对22个糜子品种进行连续2年的大田试验,测定农艺性状及产量,并进行聚类分析、灰色关联度分析、主成分分析。【结果】从农艺性状上看,内糜5号的单穗重、穗粒重、产量均在22个品种中表现最好。通过聚类分析,可将22个品种分为六类:前三类(Ⅰ、Ⅱ、Ⅲ)共12个品种,具有高产潜力;第四类和第五类(Ⅳ、Ⅴ)共5个品种,属于早熟型;第六类(Ⅵ)有5个品种,生物量大。通过灰色关联度分析及主成分分析对各品种进行综合评价,内糜5号的灰色关联度和综合得分均最高。【结论】22个糜子品种中,内糜5号的单穗重、穗粒重和产量均表现最佳,较为适宜在鄂尔多斯市种植。

Abstract: 【Objective】 To screen high-quality Panicum miliaceum L. varieties suitable for cultivation in Ordos City,Inner Mongolia,with the aim of promoting rational utilization of P. miliaceum L. germplasm resources. 【Methods】 Field experiments were conducted on 22 P. miliaceum L. varieties over two consecutive years. Agronomic traits and yield were measured,followed by cluster analysis,grey relational analysis,and principal component analysis. 【Results】 Regarding agronomic traits,Neimi No. 5 exhibited the best performance among the 22 varieties in terms of single panicle weight,grain weight per panicle,and yield. Through cluster analysis,the 22 varieties were classified into six groups:the first three groups(Ⅰ,Ⅱ,and Ⅲ),comprising 12 varieties,demonstrated high yield potential;the fourth and fifth groups(Ⅳ and Ⅴ),comprising 5 varieties,were early-maturing types;the sixth group(Ⅵ),comprising 5 varieties,exhibited large biomass. Comprehensive evaluation of all varieties using grey relational analysis and principal component analysis indicated that Neimi No. 5 achieved the highest grey relational degree and comprehensive score. 【Conclusion】 Among the 22 P. miliaceum L. varieties,Neimi No. 5 showed the best performance in single panicle weight,grain weight per panicle,and yield,and is therefore well suited for cultivation in Ordos City.
