Abstract
Viable ‘Delicious’ pollen set nearly 20% of emasculated ‘McIntosh’ flowers, while self-pollination resulted in O set. The set resulting from a mixture of self + killed ‘Delicious’ (recognition) pollen exceeded that from viable ‘Delicious’ pollen. While self-pollination of emasculated ‘Golden Delicious’ flowers produced a small set, viable ‘Delicious’ pollen set nearly 4 times as many fruits. A mixture of self + recognition pollen was slightly more effective than was viable ‘Delicious’ pollen.
Seed numbers in ‘McIntosh’ fruits set with self + recognition pollen were only slightly lower than in those set with viable pollen of ‘Delicious’. In ‘Golden Delicious’, however, the mean seed content of fruits set with ‘Delicious’ pollen was 3 times greater than in those set with self + recognition pollen. The mean seed content of the few ‘Golden Delicious’ fruits set by traditional self-pollination was lower than in those fruits set with self + recognition pollen.
