Tetraploid Seeds

Tetraploid seeds contain four sets of chromosomes rather than the typical two found in diploid cannabis plants. This chromosomal doubling occurs naturally in some populations or can be induced artificially through chemical treatment during seed development. Tetraploid plants often exhibit larger flowers, thicker stems, and increased vigor compared to their diploid counterparts, making them of interest to breeders exploring morphological traits. The breeding implications of tetraploidy include potential fertility challenges and altered expression of inherited characteristics. Tetraploid lines remain relatively uncommon in commercial seed production due to propagation complexities, though some breeders maintain them for research and trait exploration.

Breeders working with tetraploid genetics study how chromosome multiplication affects plant architecture, resin production patterns, and seedling vigor. Tetraploid lines can serve as breeding tools to create novel hybrids or explore how fundamental cellular changes influence horticultural performance.
