Abstract:

The aims are to study the relationship between the grain-related morphological traits and grain weight of wheat, screen out varieties with excellent grain morphological traits and provide reference for the genetic improvement of grain morphology-related traits of wheat. 76 main wheat varieties promoted in Shanxi Province were used as tested materials, and seven grain-related traits of wheat were measured, analyzed and evaluated by principal component analysis and cluster analysis. The thousand-grain weight of the tested materials was extremely and positively correlated with grain area, grain width, grain circumference and grain length, and negatively correlated with the length-width ratio of grain. The tested wheat varieties were clustered into three categories based on the comprehensive evaluation value (D value), among which category I-1 had the highest comprehensive evaluation value, including two varieties of No.60 and No.72, with an average D value of 0.896 and the best overall performance of grain-related traits, especially thousand-grain weight, grain area and grain circumference. The thousand-grain weight, grain area and grain circumference can be used as the important indexes for the investigation of wheat grain traits.

Key words: wheat, grain morphology, correlation analysis, cluster analysis, thousand-grain weight
