图3 产量性状与倒伏性状的相关性分析 NMSN：主茎节数；NMSB：主茎分枝数；NGPP：单株粒数；GWPP：单株粒重；FWPP：单株鲜重；TGW：千粒重；GDMA：籽粒干物质积累量；GY：籽粒产量；PH：株高；SHCG：茎秆重心高度；SL：茎长；ST：茎粗；SWT：茎秆壁厚；SD：茎秆密度；SF：茎秆充实度；SBS：茎秆抗折力；SLRI：茎秆抗倒伏指数。“*”表示显著相关（P < 0.05），“**”表示极显著相关（P < 0.01）。

Fig.3 Correlation analysis of yield traits and lodging traits NMSN: number of main stem nodes; NMSB: number of main stem branches; NGPP: number of grains per plant; GWPP: grain weight per plant; FWPP: fresh weight per plant; TGW: 1000-grain weight; GDMA: grain dry matter accumulation; GY: grain yield; PH: plant height; SHCG: stem height of center gravity; SL: stem length; ST: stem thickness; SWT: stem wall thickness; SD: stem density; SF: stem fullness; SBS: stem bending strength; SLRI: stem lodging resistance index.“*”indicates significant correlation (P < 0.05), “**”indicates extremely significant correlation (P < 0.01).
