Yield traits of WSM and OsHXK1-Cas9 plants seeded in the fall seedings. (A) Images of WSM, CH2/W, and CH3/W plants at the flowering stage. Bar = 20 cm. (B) Comparisons of panicles and 100 grains of WSM, CH2/W, and CH3/W plants. Bar = 5 cm (top), 2 cm (bottom). (C) Tiller number of WSM, CH2/W, and CH3/W plants. (D) Height of WSM, CH2/W, and CH3/W plants. (E) Length per panicle of WSM, CH2/W, and CH3/W plants. (F) Number of grains per panicle of WSM, CH2/W, and CH3/W plants. (G) Single-plant yield of WSM, CH2/W, and CH3/W plants. (H) Seed setting rate of WSM, CH2/W, and CH3/W plants. (I) 1000-grain weight of WSM, CH2/W, and CH3/W plants. The data are the means ± SDs; *, 0.01 ≤ p < 0.05; **, 0.001 ≤ p < 0.01 according to Student’s t-test.
