Comparison of grain size and spikelets epidermal cells between NIL-qGL7Nip and NIL-qGL7IL188. a, Mature grains of NIL-qGL7Nip and NIL-qGL7IL188. Scale bar, 6 mm. b–d, Grain length (GL), grain width (GW), and 1000-grain weight (TGW) for NIL-qGL7Nip and NIL-qGL7IL188. Data are given as mean ± (n = 20). ** indicate significant difference at 0.01 level. e–f, Outer epidermal cells of grain hulls of NIL-qGL7Nip and NIL-qGL7IL188. Bars = 100 μm. g–h, The average length and width of outer epidermal cells. (n = 10). i–j, Inner epidermal cells of grain hulls of NIL-qGL7Nip and NIL-qGL7IL188. Bars = 100 μm. k–l, The average length and width of inner epidermal cells (n = 10)
