Choda #6 Liquid Culture

Choda #6 — The Middle Ground in PE Mutant Isolation Research

Choda #6 occupies a strategic position in the Choda isolation series — sitting between the earlier #2 and the later #15, it represents a mid-point in the selection process that shaped these PE mutant genetics. For researchers conducting comparative studies across the Choda lineage, the #6 isolation provides the critical middle data point that transforms a simple “early vs. late” comparison into a three-point progression, revealing whether phenotypic changes across isolation numbers are linear, stepped, or variable.

This liquid culture contains live Choda #6 mycelium, specifically selected for researchers building complete Choda isolation series comparisons or seeking a mid-range expression of the Choda PE mutant phenotype.

Research Characteristics

Choda #6 mycelium demonstrates growth characteristics that fall between the earlier and later Choda isolations. Colonization speed is moderate, consistent with PE mutant genetics, with rhizomorphic growth that develops in organized but unhurried patterns. The mycelial mat is dense and white, with growth margins that advance steadily across culture media.

Morphologically, Choda #6 expresses the characteristic squat, thick proportions of the Choda phenotype. As a mid-series isolation, the degree of expression may fall between #2 and #15 — showing more pronounced Choda characteristics than the earlier isolation but potentially less extreme than the later, more heavily selected #15. Documenting these gradations precisely is one of the primary research values of maintaining multiple numbered isolations.

Spore production is moderate, consistent with PE mutant genetics. The deposits are adequate for basic morphology work and comparison studies. Spore morphology falls within standard cubensis parameters, with any inter-isolation variations most visible through careful measurement and side-by-side microscopy.

Strain Background

Choda #6 was the sixth isolation selected from the Choda PE mutant lineage. In the isolation workflow, #6 represents a selection made after the initial characterization work (represented by early numbers like #2) but before the extensive refinement cycles that produced later isolations like #15. This chronological position in the selection history gives #6 a specific role in comparative research — it shows the state of the genetics after moderate selection pressure.

The Choda lineage itself originated as a spontaneous PE mutation characterized by dramatically altered proportions — an extreme width-to-height ratio in the stem that creates a distinctive, unmistakable growth form. All numbered Choda isolates descend from this original mutation, with each number reflecting a separate selection event from the ongoing culture work.

Storage & Handling

• Store at 2–8°C (35–46°F) in a cool, dark location
• Do not freeze — freezing destroys live mycelium
• Use within 30 days of receipt for best viability
• Shake gently before use to redistribute mycelium
• Work in a clean environment to maintain culture integrity

Frequently Asked Questions

Why is Choda #6 important for comparative research?

In any comparative study, having a middle data point is critical. Choda #6 bridges the gap between the early #2 isolation and the later #15, allowing researchers to determine whether changes across the isolation series are gradual, sudden, or non-linear. Without #6, you can only compare extremes. With it, you can map the full trajectory of phenotypic change across the selection process.

Can I purchase just Choda #6, or should I get the complete set?

Choda #6 has standalone research value — it’s a legitimate PE mutant strain with distinctive morphology that is interesting on its own. However, the maximum research value comes from comparing #2, #6, and #15 together. The three isolations form a complete comparative set that is unique in cubensis mycology — few other strains offer multiple numbered isolations for controlled comparison.

How does Choda #6 differ from the Choda spore syringe you sell?

The Choda spore syringe contains dormant spores from the Choda lineage, useful for spore morphology studies under microscopy. This Choda #6 liquid culture contains live mycelium from a specific numbered isolation, useful for studying growth patterns, colonization behavior, and hyphal morphology. The two formats answer different research questions and complement each other in a comprehensive study of the Choda genetics.
