小麦新品种郑麦9134高产稳产表现及其遗传特性解析
Analysis of High and Stable Yield Performance and Genetic Characteristics of New Wheat Cultivar Zhengmai 9134
摘要
Abstract
Based on the data from the regional(2019-2021)and production trials(2020-2021)of wheat varieties resistant to Fusarium head blight in Henan Province,this study systematically analyzed the high and stable yield performance of Zhengmai 9134 and the relationship between yield and its components.Meanwhile,by using the 660K wheat chip and 0.1K functional chip,the genetic characteristics were deeply analyzed to provide a theoretical basis for its production application and parental utilization.The results showed that Zhengmai 9134 had good characteristics with high and stable yield and wide adaptability.Compared with the control variety Bainong 207,the average yield of Zhengmai 9134 reached 7 383.5 kg/ha,with increase of 6.63％;the average high stability coefficient of Zhengmai 9134 was 82.01％,with increase of 5.66 percentage points;and the average adaptation degree of Zhengmai 9134 was 78.31％,much higher than the control.Through the correlation analysis and path analysis of yield and its three components,it was found that the effective spike number had the highest direct effect on yield,followed by the thousand-grain weight and grain number per spike.The genetic contribution of Zhengmai 0943 to Zhengmai 9134 was slightly greater than that of Xinmai 22,and the genetic transmission rates were 51.07％and 48.00％,respectively.In addition,the genetic contribution of the parents of Zhengmai 9134 had genome-specific differences.Among them,Xinmai 22 had a higher genetic transmission rate at the A and D genome levels,which were 65.19％and 68.07％,respectively,while Zhengmai 0943 had a higher genetic transmission rate at the B genome level,which was 69.85％.Zhengmai 9134 aggregated multiple important functional genes,including five QTL loci with resistance to stripe rust(Yr29,QYrqin.nwafu-2AL,QYrqin.nwafu-2BL,QYr.nwafu-3BS and QYr.nwafu-4BL),two genes with resistance to leaf rust(Lr37 and Lr67),two loci with resistance to Fusarium head blight(QFhb.hbaas-5AS and QFhb.caas-5AL),two grain weight genes(Tabas1 and TaGW2-6A),and one gene related to grain size(QGl-4A).关键词
