Self-fertility in Bullace, Damson, and Mirabelle

Prunus domestica L. subsp. insititia (L.) C. K. Schneid.

Most Bullace, Damson, and Mirabelle varieties are self-fertile, allowing them to set fruit without cross-pollination. This trait ensures a stable yield even under unfavorable weather conditions or low insect activity.

In the reference 13 varieties crop Damson, where this is mentioned in the description.

To assess the degree of self-fertility in these cultivars, branches with flower buds are isolated using special bags before blooming begins. The primary indicator is the percentage of fruit set relative to the total number of flowers. Varieties showing results from 0 to 4 percent fruit set are classified as self-sterile.

Despite the ability to self-pollinate, it is recommended to select cross-pollinator varieties that bloom during similar periods to increase productivity and yield stability in commercial orchards. The use of self-fertile varieties allows for planting individual trees, which is optimal for small-scale gardens.
