图中箱体上下边代表25%和75%位点,上下须线代表1.5倍四分位数,箱体中横线代表中位数,圆点代表平均值,菱形点代表离群值,不同字母表示差异显著（LSD检验,P<0.05）。下同
Fig. 4. NHI of wheat varieties released in different years
The box boundaries indicate the 25th quartiles and 75th quartiles; the whiskers indicate the 1.5 times the interquartile; solid lines and circles in the boxes indicate the median and mean, and the rhombus points indicate the outliers. Different letters on the boxes indicate a significant difference (LSD test, P<0.05). The same as below
