To determine the degree of self-fertility in pears, a method involving the isolation of at least 200 buds prior to flowering is used. The level of the trait is assessed based on the percentage of fruit set: cultivars with a fruit set of more than 20% are considered fully self-fertile, those with 10% to 20% are partially self-fertile, and the rest are classified as self-sterile.
Self-fertility in this crop often correlates with the ability for parthenocarpy, which allows for harvest even under unfavorable weather conditions. Despite the possibility of establishing single-cultivar orchards, the presence of pollinizer cultivars remains an important factor that increases yield by 20–30%.
