Comparison of phenotypes (a–c), major agronomic traits (d–i) and breaking force (j leaves and k culms). a Leaf. b The second internode of main culm from the top. c Plants two weeks after heading. Bars represent standard deviations of three independent measurements. WT: Nipponbare; F1: Obtained from mutant Bc19 crossing with WT. Double-asterisk signifies statistically significant difference compared to the wild type at p < 0.01. Scale bar equals 1 cm in a–b and 10 cm in c
