早秋大麦主要农艺性状与产量的多重分析
Multiple Analysis of the Main Agronomic Characters and Yield of Early Autumn Barley
摘要
Abstract
[Objective]To explore how to coordinate the relationship between the three yield components factors of early autumn barley,and to improve the yield.[Method]Screening test on early autumn barley varieties was carried out for three consecutive years.Changes in agronomic traits were observed.Relationship between main agronomic traits and yield was researched through correlation analysis, grey correlation analysis and grey correlation analysis.[Result]Among the main agronomic traits of barley,the correlation degree of traits with yield from high to low were in the order of effective ears,filled grains per ear,plant height,1 000-grain weight,total tillers,basic seedlings.Their direct influencing degrees on yield from big to small were in the order of filled grains per ear,effective ears,1 000-grain weight,plant height,basic seedlings,total tillers. Their correlation degrees to yield from big to small were in the order of filled grains per ear,effective ears,1 000-grain weight,plant height,total tillers, basic seedlings.[Conclusion]Filled grains per ear and effective ears were the major factors influencing the yield of early autumn barley.关键词
