Phenotypic characterization of pmm1 mutants. a Plant morphology between WT (ZH11) and three alleles of pmm1 mutants. b Panicle architecture between WT and three alleles of pmm1 mutants. c Plant morphology of F1 plants of pmm1–1/pmm1–2 and pmm1–1/pmm1–3. d Spikelet morphology between WT pmm1–1 mutants. e-h Comparison of the primary branch number (PBs) (e), secondary branch number (SBs) (f), grain number per panicle (g) and 1000-grains weight (h) between WT and pmm1–1. Data are shown as means ± SE (n = 10). Significant at **P < 0.01 and *P < 0.05
