What Gets Lost When Every Seed Is Female

Walk through most seed shops today and the regular section is the shelf at the back: smaller every year, priced lower than the feminized packs next to it, and bought by a shrinking group of people who understand exactly what they are after. It is easy to read that as obsolescence. It is nearer to the truth to read it as a library shrinking while the paperback rack next door grows. Every female-only line began as a regular one, every new cross needs a male at some point in its history, and the diversity of cannabis genetics that survives at all exists because somebody held onto regular seed. Specialists such as https://breederregularseeds.com carry lines that trace to the 1980s, offered in packs of 10 seeds because a pack is meant to be a population, not a single plant. This article sets out the case for that half-male pack: what the male is for, what a grower loses by not seeing one, and how to get value with a pack instead of a clone.

Not Just Pollen

The easy account of a male cannabis plant is „the one that makes pollen“, and for a flower grower that is all it. For a breeder it is half the genome of every seed which follows, and that half is chosen with the same care as the female.

A male passes on structure, hybrid vigour, maturation speed, resistance to mould and pests, trichome density and the aromatic chemistry exactly as the female does; it simply shows some of those traits less visibly since it does not produce a smokable flower. Breeders who breed with regular seed invest at least as much time selecting males as females, and this is the work that a feminized line inherits and cannot repeat. Reversing a female gives pollen; it does not give a second line of selected traits.

What Happens When Lines Are Only Selfed

A great deal of the feminized market is built from S1 seeds: a single famous clone, treated and crossed with itself. Each generation of that process halves the surviving genetic variation, and after a couple of generations what is left is essentially one plant expressed in marginally different forms.

That is acceptable for a grower who needs that single plant. It is a loss for everyone who comes after. Recessive weaknesses emerge: intersex tendencies, weak stems, susceptibility to one particular mould. Qualities that existed in the parent line but absent in the chosen clone vanish from the population altogether. A decade of such breeding produces a market crowded with variations of the same few clones, and a anyone wanting to create something different discovers there is little remaining to cross. Regular seed from an outcrossed line is the reservoir that refills the pool, and that reservoir can only persist as long as people grows it.

How to Judge a Male

Guides on selecting females are everywhere; guidance on choosing males is rare, because most people do not keep one past the first week of flower to look. For a grower producing seed, these are the marks breeders look for.

• Stability. Any male that at the same time forms female flowers under ordinary stress is rejected without exception; that tendency is the last thing worth breeding into a line.
• Structure. Short internodes, a strong central stem and branching that resembles the intended female shape are passed on; a lanky, weak-stemmed male passes that down too.
• Restraint. Males that release huge amounts of pollen early are frequently also the least selected genetically; many breeders prefer steady producers.
• Resin on the stem. Scratch a stem or a flower cluster and smell it. A male with trichomes on its sepals and a clear scent suggests it holds the terpene genes that are worth passing on.

A Pack Is a Population

The mistake first-time regular-seed growers make is treating a pack as 10 attempts at the one plant. It is nothing of the kind. A pack from a real outcrossed line is a sample of a population, and the value of growing it is to see the range and select from it.

Roughly half the plants will be male, which means a pack of 10 seeds gives around five females to evaluate and five males to either cull or judge for breeding. Among the females, look for real variation: stature, finishing time, smell, bud structure, tolerance. This spread is not a flaw in the seed; it is what the seed is for. The grower who keeps the best female and the best male has something a feminized pack cannot offer: a pair of selected parents which are their own.

Three Ways to Cross

Holding selected parents means making the next generation, and here the options multiply. The main methods cover most of what home breeders do.

• 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 selection at all. This is how landrace lines are kept going, and it is the correct method when the aim is preservation not improvement.
• Backcross. Take a selected seedling back to one of its parents to fix a specific quality. It tightens the genetics fast and is used when a single parent shows something worth concentrating and the other brought mostly vigour.
• Selected cross. One chosen male to one or several chosen females, everything else removed. The offspring inherit the traits of two selected plants and express less variation than the original pack. Repeated over several rounds with consistent choices, this is how a stable line is made.

All three require only a separate space for the male, a paintbrush or a small bag, and patience. Not one of them needs the chemical reversal that feminized seed-making requires.

Keeping Old Lines Alive

A number of lines were never feminized and likely never will be: landraces gathered from places where cannabis grew for centuries, and heirloom crosses from the early decades of modern breeding. They are sold as regular seed because the breeders maintaining them regard the population as the entire point, and selfing a single clone would erase precisely what makes the line worth keeping.

Growing a landrace from regular seed is a different experience from running a modern hybrid. Expect large variation, long flowering periods in equatorial lines, lanky plants, and traits that make sense in a mountain valley but not under a small room. There will be too flavours and chemistry that do not appear in the commercial market anywhere. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line marked with its origin of origin and the number of generations it has been reproduced from the first collection.

When the Library Is the Wrong Shop

None of the above makes regular seed the right option for everyone, and claiming that it is would the category no favours.

A grower with space for three plants who wants every one of them to flower is better off with feminized seed. The same is anyone who cannot afford to inspect the plants each day around the start of flower, since a late male in a confined space seeds the whole crop inside days. Someone growing a single autoflower on a balcony has no value from a pack they cannot select from. And a buyer who is after a known famous cut repeated exactly is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to choose, to keep and at some point to produce something new; for everyone else the regular shelf is best left alone.

Practicalities

Breeder Regular Seeds sends each order in plain parcels with the breeder’s packs intact inside and nothing on the outside to indicate the contents. Orders to the United States are not accepted, because seed importation is restricted there. Seed law differs widely by country: in many places owning seeds is legal as collectables while germinating them is not, and in others the two are permitted under licence or neither is. Knowing the rules where you live is the buyer’s responsibility, and no part of this article should be read as legal advice.
