RKS Breeder Documentation
This reference benchmark documents the upper-percentile phenotype of the Mandarin stabilized line. The breeding criteria for this strain prioritize hybrid balance: no single terpene dominating the profile, trichome density above the cohort minimum, and a tight flower-time window. The reference numbers reflect the chosen phenotype carried forward through stabilization. The line is built on Autoflowering Hybrid (Undisclosed Lineage) heritage, with each generation selected to fix the traits that define Mandarin.
Breeding Objective · M-Pheno #3
- Fix the phenotype expression that defines this strain
- Improve resistance to common pathogens under indoor SOP
- Maintain commercial yield bands across cycles
- Reduce flower-window variance ≤ 5 days within cohort

Phenotype Consistency & Stabilization Line
Phenotype Consistency
The values reported on this Certificate reflect the top-performing phenotype(M-Pheno #3) selected from a 15-plant cohort of the RKS Mandarin Autoflower line. Across three production cycles, individual plants from this seed line have fallen within a 10–15% variation envelope on total cannabinoids and total terpene yield when grown under comparable indoor conditions.
Note: phenotype expression is subject to environmental conditions (light, nutrients, VPD, training). These figures are not a guarantee of grow outcome.
Stabilization Status
AUTOFLOWERThis line has been stabilized through successive inbred generations with phenotype-driven selection. Trait-locking criteria for the M-Pheno #3 selection:
- Balanced terpene expression (no single >50% of profile)
- Predictable hybrid effect profile
- Cohort variation ≤ 12% on total cannabinoids
- Trichome density ≥ 28%
- Resistance to common mildew strains
- Flower window 8–10 weeks

Disclaimer of variation · Results published in this Certificate represent a selected phenotype of the RKS Mandarin Autoflower stabilized line under controlled indoor conditions. Individual seedlings may produce plants that vary by approximately 10–15% on total cannabinoids and terpene output, and may express alternate phenotypes within the line. Final cannabinoid and terpene expression is subject to cultivator inputs, lighting, substrate, nutrient regime, environment, and training technique. This document is intended as a reference benchmark of the genetic potential of the RKS Mandarinline, not as a guarantee of any individual plant’s outcome.
Note for seed buyers · This Certificate analyzes mature, cured flower from a selected reference plant cultivated by the RKS breeding team under controlled conditions. Seed-grown plants may vary slightly from the tested phenotype depending on environment, nutrient regime, and grower input. For best expression of the M-Pheno #3profile, follow the cultivation reference outlined in the “Expected Grow Outcomes” section above.
