S1 Seeds
S1 seeds represent a specific reproductive category within cannabis breeding: seeds produced by self-pollinating a female plant without crossing to a male. The "S" indicates selfing, and "1" denotes the first generation of this process. S1 seeds contain genetic material exclusively from the maternal plant, making them genetically identical to the parent in nuclear DNA (though epigenetic variation may occur). Breeders working in this category use S1 generation seeds to preserve and stabilize desired traits from a single female specimen, particularly when a male of matching quality is unavailable or when rapid trait isolation is the goal.

S1 seeds are commonly employed in line-stabilization programs and for creating feminized seed stocks through forced female reproduction. They allow breeders to multiply an exceptional clone without introducing new genetic material, useful for conserving rare or unstable genotypes across generations.
