What Gets Lost When Every Seed Is Female

Walk through most seed shops today and the regular section is a shelf at the back: smaller every year, marked cheaper than the feminized packs next to it, and bought by a shrinking number of people who know exactly what they are looking for. It is easy to read that as the end of a technology. It is nearer to the truth to see it as a library shrinking while the paperback rack next door expands. Every feminized line began as a regular one, every new cross needs a male at some point in its pedigree, and the diversity of cannabis genetics that survives at all exists because someone kept regular seed. Specialists such as https://breederregularseeds.com carry lines going back to the 1980s, sold in packs of 10 seeds since a pack is meant to be a population, not a one plant. This article makes the case for that unfashionable pack: what the male is for, what a grower loses by not seeing one, and how to work with a pack rather than a copy.

What a Male Plant Is Actually For

The easy account of a male cannabis plant is “a pollen source”, and for a flower grower that is the whole of it. To a breeder it is half the genome of every seed that follows, and that half is chosen with the same attention as the female.

A male passes on structure, vigour, maturation time, tolerance to mould and pests, resin production and the terpene profile just as the female does; it simply expresses some of those traits less visibly because it does not grows a finished flower. Those who breed with regular seed invest at least as much time selecting males as females, and this is the work that a feminized cross borrows and cannot repeat. Reversing a female gives pollen; it does not provide a different set of selected genes.

The Narrowing

Much of the feminized catalogue is made from S1 seeds: a single popular clone, treated and pollinated with itself. Each generation of that selfing cuts in half the surviving genetic variation, and after two rounds what remains is close to one plant repeated across slightly different forms.

That is fine for a grower who needs that single plant. It is a loss for everyone downstream. Recessive faults surface: intersex tendencies, brittle stems, susceptibility to one particular mould. Qualities that were present in the original line but not in the chosen clone vanish out of the gene pool entirely. A generation of such breeding produces a market crowded with variations of a dozen clones, and a breeder trying to make something different finds there is nothing left to cross. Regular seed from an outcrossed line is the store that refills the pool, and it can only persist as long as somebody grows it.

Reading a Male Plant

Guides on choosing females are easy to find; advice on picking males is scarce, because most people never keep one past the first week of flower to look. For anyone making seed, these are the marks breeders watch for.

• Resin on the stem. Scratch a stem or a flower sac and smell it. A male with resin on its sepals and a clear scent suggests it holds the resin genes that are worth keeping.
• Stability. Any male that at the same time forms female pistils under normal stress is rejected outright; that tendency is the one thing anyone wants carrying forward.
• Restraint. Plants that dump enormous quantities of pollen all at once are often the least selected genetically; many breeders prefer steady shedders.
• Timing. A male that declares sex early and matures at the same pace as the females is far more workable than an early one that releases pollen before the female is ready.

Thinking in Numbers

The error first-time regular-seed growers fall into is treating a pack as 10 chances at the one plant. It is nothing of the kind. A pack from a genuine outcrossed line is a slice of a population, and the point of running it is to see the spread and select from it.

About half the plants will be male, which means a pack of 10 seeds gives something like five females to evaluate and five males to either discard or judge for breeding. Among the females, expect real variation: height, flowering time, smell, density, resistance. This variation is not a failure in the seed; it is what the seed is selling. The grower who keeps the strongest female and the best male now owns something a feminized pack cannot supply: a line of selected parents that are their own.

Making Your Own Seed

Owning selected parents is only worth something if producing the next batch, and here the choices open up. Three approaches account for most of what small-scale breeders attempt.

• Backcross. Take a selected offspring again to one of its original parents to lock in a specific trait. It narrows the genetics quickly and is used when a single parent has something worth keeping and the second brought mostly vigour.
• Open pollination. Let each male pollinate each female. It preserves the whole range of the line, makes a large quantity of seed, and involves no choosing at all. This is how traditional lines are maintained going, and it is the correct method when the goal is preservation rather than refinement.
• Selected cross. One picked male on one or a few chosen females, every other plant else culled. The offspring carry the qualities of two selected plants and express less spread than the parent pack. Repeated over several rounds with stable choices, this is how a stable line is made.

Each of these require nothing more than a separate space for the male, a paintbrush or a small bag, and a few weeks. Not one of them calls for the chemical treatment that feminized production requires.

Keeping Old Lines Alive

A number of lines have never feminized and probably never will be: landraces gathered from regions where cannabis grew over centuries, and old hybrids from the first decades of indoor breeding. They are sold as regular seed because the breeders maintaining them treat the population as the whole point, and selfing a single plant would erase exactly what makes the line worth preserving.

Growing a landrace from regular seed is a different experience from growing a modern hybrid. There will be wide variation, extended flowering times in equatorial lines, lanky plants, and traits that make sense in a mountain valley but not under a small room. Expect also flavours and effects that no longer exist in the hybrid market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, and each line labelled with its region of origin and the number of generations it has been grown out from the original collection.

Who Should Not Buy Regular Seeds

Nothing of the above turns regular seed the right choice for everyone, and pretending otherwise does the category no service.

A grower with space for a handful of plants who needs every one of them to finish is far better served with feminized seed. The same is anyone who cannot afford to inspect the plants each day around the onset of flower, because a late male in a small space ruins everything within days. A person running a single autoflower on a balcony gets no value from a population they cannot choose from. And anyone who is after a specific famous plant repeated exactly is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who intends to choose, to keep and at some point to make something of their own; for anyone else the back shelf is best ignored alone.

Practicalities

Breeder Regular Seeds sends each order in plain packaging with the original packs intact inside and no on the exterior to reveal the contents. Orders to the United States are not taken, as seed importation is not permitted there. Seed law varies sharply by country: in many places owning seeds is lawful as genetic preservation while germinating them is not, and in others the two are permitted under local rules or both is. Knowing the position where you live is the buyer’s responsibility, and no part of this article is legal advice.
