The phenotypic performance of five grain size traits in IL188 and Nipponbare

Trait	Nip	IL188
GL (mm)	7.798 ± 0.060	9.416 ± 0.133**
GW (mm)	3.087 ± 0.040	3.347 ± 0.072**
LWR	2.526 ± 0.021	2.819 ± 0.042**
GT (mm)	2.295 ± 0.035	2.171 ± 0.020**
TGW (g)	24.10 ± 0.15	34.40 ± 0.19**

Nip Nipponbare, GL grain length, GW grain width, LWR the ratio of grain length to grain width, GT grain thickness, TGW thousand grain weight. ^** indicate significance at P < 0.01
