Abstract
Correlation and multiple regression analysis of primary source-sink-translocation and yield and quality characters were analyzed to provide support for breeding of high yield and good quality wheat.These results indicated that:(1)The larger area of flag leaf is a prerequisite for high yield and good quality of wheat.The flag leaf characters have a promoting effect on yield,and flag leaf width has a greater effect than flag leaf length on yield.The flag leaf width were significant or extremely significant negative correlation with sedimentation values,stability time,development time and extension area of dough,and flag leaf width has a more obvious effect than flag leaf length on quality.(2) The relation between top internode length/second internode length and yield or quality characters were respectively negative or positive when the plant height was great than 80cm.While we can get the opposite conclusion when the plant height is less than 80cm.Uppermost internode diameter is positive correlation with all yield characters,content of grain protein and wet gluten content,and negative with sedimentation values,stability time and development time.(3)There is positive correlation between grain length,grain width,grain thickness and spike number per plant,kernel mass per spike,1 000-grain mass.negative correlation is observed between grain width,grain thickness and spike length,grains per spike.Correlations between grain length and test weight are extremely significant negative.Grain width is significant or highly significant negative correlation with grain protein content,wet gluten content,sedimentation values,stability time and development time.Significant positive correlation is observed between grain length and all quality characters except for test weight.
