Identification and evaluation of agronomic traits of different Setaria italica germplasm resources
摘要
Abstract
The identification and integrated evaluation of agronomic traits in Setaria italica germplasm resources from different sources were conducted to screen high-quality and high-yielding suitable varieties,providing a basis for Setaria italica breeding innovation,promotion of cultivation,and agricultural structure adjustment.An integrated evaluation of key agronomic traits was performed on 460 Setaria italica germplasm resources sourced from various regions.The results showed that the ranking of variation coefficients for quan-titative traits among all germplasm resources of the tested Setaria italica was as follows:total number of leaves<grain yield<spike length<spike thickness<spike neck length<thousand kernel weight<spike weight;among all agronomic traits,the length of the top second leaf showed an extremely significant positive correlation with its width(r=0.503),representing the strongest positive correlation ob-served;the total leaf count exhibited an extremely significant negative correlation with the spike neck length(r=-0.583),which was the strongest negative correlation among all analyzed traits.Principal component analysis identified five principal components,which collectively accounted for 78.4％of the total variance.The top 10 ranked Setaria italica germplasm resources by comprehensive score were Zheng 256,Louxuanfeng,Yigenqi,Majiangsheng,Banyelai,Bagu 257,Chaoyang Daisui 1,Huanggu,338A,and Xiangyang-gu.关键词
