a
The number of pollen tubes per pollinated stigma: <10, incompatible pollination; +++, compatible pollination; MS, male sterile; ND, not determined because previous generations were no longer available.
b
C. grandiflora S7S7 homozygotes were used because the C. rubella–grandiflora F2 population segregated for the S7 allele and only pollination assays with S7S7 plants are relevant.
