Hop Latent Viroid Hlv
Hop Latent Viroid (HLV) is a plant pathogen that infects cannabis and related species, belonging to the Pospiviroidae family of circular, single-stranded RNA molecules. First documented in cannabis samples in the early 2020s, HLV is transmitted through contaminated tools, propagation material, and possibly pollen. Infected plants often display stunted growth, chlorotic mottling, and reduced vigor, though symptom expression varies by cultivar and environmental conditions. Detection requires molecular testing (RT-PCR or sequencing) since visual symptoms can mimic nutrient deficiencies or other stressors. HLV presence has significant implications for seed production, clone distribution, and cultivation facility sanitation protocols.

Breeders and seed producers now incorporate HLV screening into quality control workflows to prevent pathogen spread through germplasm. Selection for HLV-free parent stock and clean propagation practices have become standard considerations in professional breeding programs and certified seed production.
