Figure 3.

Floral morphology and stigma‐anther distance of different G73N endowing resistant or susceptible genotypes. (a), (b) intact and dissected young and mature flower buds and open flowers of different genotypes, showing the physical distance between the anthers and stigma (herkogamy). (c)‐(f)mages of a single flowering spikelet that was taken from the seventh node below the meristem for different genotypes 9425‐RR (c); ‐RS (d); ‐SS (e), WT plants (f). Yellow arrows indicate flowers with intact anthers, and synchronous male and female phases that promote selfing; red arrows indicate flowers with rapidly dehiscent anthers and separated male and female phases (dichogamy). Scale bar = 2 mm for spikelet (a–d), 500 μm for flower bud and 1 mm for mature flower (e,f).
