Panicle and grain size analysis for field grown mutants (KO). a Panicle length (n = 29), b grain size parameters of unhulled grain (n = 30), c grain number and weight for corresponding grain thickness, d single grain weight for corresponding grain thickness are shown. Data represent the mean ± SE (n = 3 plants). Asterisks indicate statistical significance of difference using Student’s T-statistic with *-p < 0.05, **-p < 0.01 and ***-p < 0.001
