22个糜子品种在鄂尔多斯市的适应性评价
Adaptability evaluation of 22 Panicum miliaceum L.varieties in Ordos City
摘要
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(Ⅴ),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.关键词
