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
F1, interspecific hybrids from the A. thaliana × A. lyrata cross.
c
BC, plants from a backcross of A. thaliana–lyrata hybrids to A. lyrata.
