Hybrid background transgenics [transgenic ‘Mitchell’×P. inflata (S3LS3L)] were pollinated with pollen from P. inflata Sk1Sk1 or P. inflata S3LS3L, while Mitchell background transgenics [transgenic ‘Mitchell’×NIL Mitchell (S3LS3L, HT-BiHT-Bi)] were pollinated with ‘Mitchell’ or NIL Mitchell S3LS3L. 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.
