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.
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.
