For the percentage of fertile siliques data, fertile siliques contain at least one seed. All measurements are the means ± se from 15 to 20 plants per genotype. Rosette diameter was measured 24 d after sowing. Measurements of seeds in individual siliques were taken on primary inflorescence stems only. When two values are marked with different letters (a to f), the difference between them is significant based on Student's t test (P < 0.01). NA, not applicable.
