Hybrid background transgenics [transgenic ‘Mitchell’×P. inflata (S^3LS^3L)] were pollinated with pollen from P. inflata S^k1S^k1 or P. inflata S^3LS^3L, while Mitchell background transgenics [transgenic ‘Mitchell’×NIL Mitchell (S^3LS^3L, HT-BⁱHT-Bⁱ)] were pollinated with ‘Mitchell’ or NIL Mitchell S^3LS^3L. Data are presented as the number of fruits over pollinations. CH and CM are untransformed controls of hybrid background and Mitchell background, respectively. DT denotes a double transformant.

^*Fruit sizes were smaller than those obtained by compatible pollination. See text and Fig. 6B.
