Mandarin oranges are usually eaten plain or in fruit salads. Most canned mandarin oranges are satsumas.
Citrus fruit varieties are usually self fertile (needing the bee only to move pollen within the same flower), or parthenocarpic, not needing pollination and therefore seedless. Tangerine blossoms are an exception. They are self sterile, therefore must have a pollenizer variety to supply pollen, and a high bee population to make a good crop.
