Fig. 1. Grain phenotypes of TD70/Kasalath recombinant inbred line (RIL) population. A?H, Grain lengths, grain widths, grain thicknesses and 1000-grain weights of B-type (A-D) and C-type (E-H) plants. I, Grain lengths of D-type plants. J, 1000-grain weights of E-type plants. K-N, Grain lengths, grain widths, grain thicknesses and 1000-grain weights of F-type plants. O, Grain phenotypes of TD70, Kasalath, and all RIL genotypes. Scale bar, 10 mm. Values are Mean ± SD (n = 5). Different lowercase letters or asterisks above the bars indicate significant differences as determined using an analysis of variance followed by the LSD test for the comparison of means (P < 0.05) in the same year.

Fig. 2. Grain phenotypes of Kasalath and various near-isogenic lines (NILs). A, Grain phenotypes of Kasalath, NIL-GW2TD70, NIL-GS3TD70 and NIL-qGL3TD70. Scale bar, 10 mm. B?E, Grain lengths (B), grain widths (C), grain thicknesses (D) and 1000-grain weights (E) of Kasalath, NIL-GW2TD70, NIL-GS3TD70 and NIL-qGL3TD70. F, Grain phenotypes of Kasalath, NIL-GW2TD70/GS3TD70, NIL-GW2TD70/qGL3TD70 and NIL-GS3TD70/qGL3TD70. Scale bar, 10 mm. G-J, Grain lengths (G), grain widths (H), grain thicknesses (I) and 1000-grain weights (J) of Kasalath, NIL-GW2TD70/GS3TD70, NIL-GW2TD70/qGL3TD70 and NIL-GS3TD70/qGL3TD70. Values are Mean ± SD (n = 5). Different lowercase letters above the bars indicate significant differences determined using an analysis of variance followed by the LSD test for the comparison of means (P < 0.05).
