The Case for the Male Plant

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 beside it, and picked up by a dwindling group of people who understand exactly what they are looking for. It is tempting to read that as the end of a technology. It is closer 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 requires a male somewhere in its pedigree, and the diversity of cannabis genetics that survives at all exists because someone held onto regular seed. Dedicated sellers 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 argument for that unfashionable pack: what the male contributes, what a grower gives up by never growing one, and how to get value with a pack instead of a copy.

The Other Half of the Genome

The easy description of a male cannabis plant is “a pollen source”, and to a flower grower that is the whole of it. For a breeder it is half the genome of every seed that follows, and that half is selected with the same attention as the mother.

A male passes on growth habit, vigour, flowering speed, resistance to mould and pests, trichome production and the terpene profile exactly as the female does; it just expresses several of those qualities less because it does not grows a finished flower. Breeders who work with regular seed spend at least as much time selecting males as females, which is the effort that a feminized cross borrows and cannot repeat. Feminizing a female gives pollen; it does not give a second set of selected genes.

The Narrowing

Much of the feminized market is made from S1 seeds: a one famous clone, treated and pollinated with itself. Each round of that selfing halves the remaining genetic variation, and after a couple of rounds what is left is essentially one plant repeated across marginally different forms.

This is acceptable for a grower who wants that single plant. It is a loss for everyone who comes after. Recessive faults emerge: hermaphrodite tendencies, brittle stems, susceptibility to one particular mould. Traits that were present in the original line but absent in the selected clone vanish out of the population altogether. A generation of such breeding leaves a market full with variations of the same few plants, and a breeder trying to make something different finds there is nothing remaining to work with. Regular seed from an outcrossed line is the store that replenishes the pool, and that reservoir can only exists if people grows it.

How to Judge a Male

Articles on selecting females are everywhere; advice on choosing males is scarce, because most people do not keep one long enough to look. For anyone producing seed, the following are the marks breeders watch for.

  • Restraint. Males that dump huge amounts of pollen early are frequently the least desirable genetically; many breeders favour steady producers.
  • Structure. Short internodes, a strong central stem and branching that matches the intended female shape are inherited; a stretched, weak-stemmed male hands that on too.
  • Stability. Any male that also shows female pistils under ordinary stress is discarded outright; that trait is the last thing worth breeding into a line.
  • Resin on the stem. Rub a stem or a pollen cluster and smell it. A male with resin on its sepals and a clear scent indicates it carries the resin traits worth keeping.
  • Timing. A male that shows sex early and matures in step with the females is more workable than a very early one that sheds pollen before the female is receptive.

What 10 Seeds Actually Give You

The error first-time regular-seed buyers fall into is treating a pack as 10 chances at the same plant. It is nothing of the kind. A pack from a genuine outcrossed line is a sample of a population, and the point of growing it is to observe the range and select from it.

About half the plants will be male, so a pack of 10 seeds gives something like five females to compare and five males to discard or assess for breeding. Among the females, look for noticeable differences: stature, finishing time, aroma, bud structure, tolerance. That spread is not a flaw in the seed; it is what the seed is selling. The grower who keeps the best female and the best male now owns something a feminized pack cannot offer: a pair of selected parents which are their own.

Three Ways to Cross

Owning selected parents is only worth something if making the next generation, and here the choices multiply. The main methods account for most of what home breeders attempt.

  • Open pollination. Allow each male pollinate each female. It keeps the full diversity of the line, makes a generous volume of seed, and does no choosing at all. This is how traditional lines are kept going, and it is the correct approach when the goal is preservation not refinement.
  • Selected cross. One picked male to one or several picked females, every other plant else removed. The seeds carry the traits of two selected plants and express less spread than the original pack. Repeated over generations with consistent choices, this is how a new line is built.
  • Backcross. Cross a selected offspring again to one of its original parents to fix a particular quality. It narrows the genetics quickly and is used when one parent has something worth concentrating and the second contributed mainly vigour.

All three need only a separate space for the male, a soft brush or a paper bag, and a few weeks. Not one of them needs the chemical reversal that feminized seed-making requires.

Landraces and Heirloom Lines

A number of lines have never been feminized and probably never will be: landraces collected from regions where cannabis grew for centuries, and heirloom hybrids from the early decades of modern breeding. They are sold as regular seed because the people keeping them treat the population as the entire value, and selfing a single clone would destroy exactly what makes the line worth the trouble of keeping.

Running a landrace from regular seed is different from growing a commercial hybrid. Expect large variation, extended flowering times in equatorial lines, lanky plants, and qualities that make sense in a field but not in a small room. Expect too flavours and effects that no longer appear in the hybrid market at all. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line marked with its region of collection and the number of generations it has been reproduced from the original collection.

When the Library Is the Wrong Shop

None of the above turns regular seed into the best choice for everyone, and claiming otherwise does the product no favours.

A grower with room for a handful of plants who needs every one of them to flower is better served with feminized seed. So is anyone who cannot afford to check the plants each day around the start of flower, because a missed male in a small space seeds everything inside days. A person running a single autoflower on a balcony gets no value from a population they cannot select from. And a buyer who is after a known famous cut repeated as closely as possible is looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to select, to hold onto and eventually to make something of their own; for everyone else the regular shelf is best left alone.

Practicalities

Breeder Regular Seeds dispatches each order in plain parcels with the original packs intact inside and no on the outside to reveal the contents. Orders to the United States are not taken, because seed import is restricted there. Seed law varies sharply by country: in many places buying seeds is legal as collectables while germinating them is not, and in others the two are allowed under local rules or neither is. Checking the position where you live is the buyer’s job, and nothing of this article should be read as legal advice.
