Goldrich Apricot
Pollination & Compatibility Guide
Goldrich apricot pollination guide: partner-required Group 3 cultivar, S1S2 Group A exclusions and 750-hour provisional chill estimate.
Goldrich Needs a Compatible Apricot Partner
Well-established Group A (S1S2) with Hargrand and Lambertin-1. Own partners: Harcot, Perfection, Moorpark, Tilton — NOT Hargrand. Goldrich needs at least one compatible pollinizer from bloom group 2–4 to set a reliable crop.

Flowering Period & Overlap Window
Apricots flower before peach, plum and cherry, so bloom overlap and spring frost decide most outcomes. Self-fertility varies by origin: many Mediterranean-type cultivars set alone, while several North American releases need a compatible partner flowering at the same time.
Goldrich flowers within the apricot Group 2–4 window. Partner-dependent cultivars need a compatible apricot whose flowers overlap in the same days.

Incompatible Varieties & Exclusions (6)
These cultivars cannot serve as pollinizers for Goldrich because their flowering does not overlap, their pollen is unsuitable, or they share the same incompatibility group.
apricot incompatibility groups are only partly mapped, so only cultivars documented as reliable donors are offered. Goldbar is not one of them — that is a gap in the data, not evidence it is incompatible.

Grower Commentary: Goldrich Needs a Compatible Partner
Goldrich is a diploid apricot that needs one compatible partner in our record. Bloom was corrected to Group 3, and it carries S-alleles S1 and S2 in incompatibility Group A. Hargrand and Lambertin-1 share that group, so they cannot serve as partners. Harcot, Perfection, Moorpark and Tilton are the named options, provided their flowers overlap Goldrich in your orchard.
The stored chill estimate is about 750 hours below 7.2°C and is provisional. Check it against local winters before planting. Neither Hargrand nor Lambertin-1 is currently in the catalogue, so the tool cannot yet flag that exclusion from the other side; use the S-allele note when a nursery offers those cultivars.
Plant the partner close enough for pollinating insects to move between trees, and keep the block sheltered from cold air. Thin heavy crops, pick mid-season and confirm the rootstock with the nursery. Record bloom dates for several springs before adding rows that depend on the pairing.
Key Orchard Considerations for Goldrich
S1S2 Goldrich cannot use Hargrand or Lambertin-1 as partners.
Harcot, Perfection, Moorpark and Tilton, subject to bloom overlap.
Keep the donor close and record flowering dates.
