Gibberellin Responsive Dwarfism
Gibberellin-responsive dwarfism describes a genetic trait where plants exhibit reduced vertical growth due to altered sensitivity to gibberellic acid (GA), a key plant hormone regulating stem elongation. This trait has been documented in cannabis breeding lines, where affected plants produce shorter, more compact canopies while often maintaining or increasing lateral branching. The dwarfism phenotype is typically controlled by recessive alleles that impair gibberellin signaling or synthesis pathways. Breeders working with this category have noted variable expression across environments and genetic backgrounds, suggesting polygenic or epigenetic involvement alongside single-locus control.

Cannabis breeders select for gibberellin-responsive dwarfism to produce space-efficient cultivars suitable for controlled indoor environments and dense cultivation systems. Crossing dwarfing lines with standard-height parents allows creation of semi-dwarf hybrids that balance reduced light penetration issues with yield per square meter.
