Comparisons of grain size between ‘Dongjin’ (WT) and lgs1. a Comparison of WT and lgs1 seeds (unhulled and hulled). Scale bar, 5 mm. b-d Comparisons of grain length (b, n = 30), grain width (c, n = 30), and 1000-grain weight (d, n = 3) of unhulled seeds between WT and lgs1. e-g Comparisons of grain length (e, n = 30), grain width (f, n = 30), and 1000-grain weight (g, n = 3) of hulled seeds between WT and lgs1. h Grain appearance of WT (left) and lgs1 (right) at a series of developmental stages as indicated. Scale bar, 5 mm. i Grain-filling process of WT and lgs1 (n = 5). Data are the mean ± SD. Student’s t-tests were used to generate the P values. *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001
