图1 小麦种质各性状指标耐低氮系数（A）和耐高氮（B）系数的相关性分析 PH：株高;SL：穗长;FLL：旗叶长;FLW：旗叶宽;SD：茎粗;FSN：可育小穗数;GNPS：穗粒数;TKW：千粒重;GL：粒长;GW：粒宽;GWPS：单穗产量。*和**分别表示在P<0.05和P<0.01水平差异显著。圆圈的大小代表相关系数的大小,蓝色表示正相关,红色表示负相关。下同

Fig. 1 Correlation analysis on low（A）and high（B）nitrogen tolerance coefficient of each trait in wheat germplasm PH: Plant height; SL: Spike length; FLL: Flag leaf length; FLW: Flag leaf width; SD: Stem diameter; FSN: Fertile spikelet number; GNPS: Grain number per spike; TKW: Thousand kernel weight; GL: Grain length; GW: Grain width; GWPS: Grain weight per spike. * and ** refer to the different significance at P<0.05 and P<0.01 levels, respectively. The size of the circle denotes the size of the correlation coefficient, blue represents positive correlation, red represents negative correlation. The same as below
