Nectarine self-fertility is determined by a cultivar's ability to set fruit upon self-pollination and is a key factor in the design of intensive orchards.

where this is mentioned in the description.
The level of nectarine self-fertility is estimated by the percentage of fruit set under flower isolation, which excludes cross-pollination. The ratio of the number of stamens to the pistil length is used as an indirect morphological marker, with this index typically being lower in self-fertile forms.
Cultivars are classified by fruit set: high self-fertility exceeds 20%, moderate is 10–20%, partial is less than 10%, while self-infertile cultivars yield virtually no fruit under self-pollination. High self-fertility ensures yield stability without the need for selecting pollinizer cultivars.
