Narrative
Donation on 20230822 contained 1 seed packet.

Donor Narrative: collected by Delicorganic. Maintained in Greece based on original early 1990s stock. in Rethimno, Crete. Type: Heirloom / Landrace. Purpose: Sinsemilla – but presumed derived from a Greek / Levantine hashish landrace. Narrative: Seeds were collected in the early 90’s from the mountainous region of Rethimno on the island of Crete. The strain was then maintained elsewhere in Greece by a collector. As with other Greek heirlooms, Cretan is now cultivated for bud production, not hashish (ie, resin), although it has many characteristics of the hash plant type. A fast-flowering strain with an incredible range of aromas, it has a complex cannabinoid profile including minor cannabinoids, medium-high THC, and markedly low CBD. Effects are like those of other Greek cultivars such as Kalamata Red: energetic and creative in small doses, but at higher doses very intense, calming, and mildly trippy. Aromas and flavours are herbal, hashy, and woody, with eucalyptus, helichrysum, turmeric, and dittany. Cretan doesn’t stretch like a pure Sativa but can reach 3 to 4 metres with strong branching and desriable short internodal spacing. Finishes mid to late October outdoors in Crete, with a flowering of 11 to 12 weeks. Cretan has acclimatized to the harsh environmental conditions of the mountainous regions in Crete. These include very hot summer days (40° to 45°C) and strong winds at 400 to 500 metres above sea level. Cretan farmers grew on rocky slopes to avoid police helicopters, so plants adapted to growing untended in rocky soil, with very little watering and no fertilizer. Guerilla growing techniques have resulted in a cultivar showing extremely vigorous individuals that can cope excellently under many different environmental stresses. Crete has a long tradition of guerilla cannabis cultivation. Here’s a genetic analysis of Cretan indicating a very rare landrace genotype with no known direct relatives. Height: 3 to 4 meters. Flowering: 11 to 12 weeks. Regional Harvest: Second half October. Yield: 500 to 600 grams of dried flowers per plant (outdoors). THC: 10% to 13%. Aromas: Herbal, earthy, woody, eucalyptus, helichrysum, turmeric, dittany. Taste: Hashy, herbal. High: Intense, calming, long-lasting, with slight body effect. Characteristics: Light-green / gold flowers” [Donor describes this accession as a heirloom landrace, see:] REMARKS

Accession was (or attempted to be) included in the 2024 USDA-ARS Hemp Germplasm Laboratory and HudsonAlpha genome sequencing and phenotyping trial in PGRU Wellington Zone 01 [curator notes 2024:] Dramatic purple stems in some individuals. In a very preliminary screening of several plants in 2024, plants seemed likely susceptible to septoria.
