Figure S1
Figure S1. Schematic diagram for the pollen competitive ability (PCA) test procedure for lines 1680 and UH400. Two kinds of pollen were pollinated on one plant in different time intervals. M1= Male 1 parent; M2= Male 2. ●= pollinations performed.
Figure S2
Figure S2. Punnett square for genetic transmission of the sed1 haplotype through male and female gametes in F2 populations with different survive rates ri for the different genotypes.
Figure S3
Figure S3. Ear phenotype in reciprocal crossing and selfing ears. A: ear phenotypes of crosses, when inducers were used as female parents and normal lines as male parents, showed rare defective kernels and good seed set rate; B: self-pollinated ear phenotypes of different inducers; C: ear phenotypes of crosses, when normal lines were used as female parents and inducers as male parents, showed many defective kernels and pool seed set rate.
