Comparison of seed colour and hull lignin content among high- (black-seeded) and low-lignin (yellow-seeded) lines. (A) Seed colour of H- and L-lignin lines. Bar, 2 mm. (B) Statistical analysis of the hull lignin contents (%) of the extreme lines. The lowercase letters and capital letters represent significance (α) at 0.05 and 0.01, respectively. (C) Microscopic observation of H- and L-lignin lines. Te, taste; mu, epidermal mucilage; p, palisade layer; en, endothelial layer. Bars, 200 μm
