Mediterranean Climate Landraces

Mediterranean climate landraces are cannabis populations that evolved in regions with warm, dry summers and mild, wet winters—including areas around the Mediterranean Sea, parts of California, and similar climatic zones. These populations typically developed over centuries under selective pressure from local cultivation practices, resulting in plants often characterized by shorter flowering times, compact structures, and adaptation to water-limited growing conditions. Lineage records frequently report these landraces show resilience to powdery mildew and heat stress, traits valued in breeding programs targeting warm-climate cultivation. The genetics within Mediterranean landraces remain diverse, as different regions (Morocco, Lebanon, Greece, Spain) developed distinct phenotypic signatures. Modern breeders working in this category often crossbreed these landraces with other lines to intr

Breeders utilize Mediterranean landrace genetics to develop cultivars suited to outdoor production in warm, arid regions and to introduce drought tolerance and disease resistance to existing elite lines. These populations serve as foundational material for understanding environmental adaptation at the genetic level.
