Browse through most seed shops today and the regular section is the shelf at the back: smaller every year, marked lower than the feminized packs next to it, and picked up by a shrinking number of people who understand exactly what they are after. It is easy to read that as obsolescence. It is closer to the truth to see it as a library shrinking while the bookshop next door grows. Every female-only line began as a regular one, each new cross requires a male somewhere in its history, and the breadth of cannabis genetics that survives at all exists only because somebody held onto regular seed. Specialists such as https:\/\/breederregularseeds.com<\/a> stock lines going back to the 1980s, offered in packs of 10 seeds since a pack is intended to be a population, not a one plant. This article makes the case for that half-male pack: what the male is for, what a buyer loses by never growing one, and how to work with a pack rather than a clone.<\/p>\n

The Other Half of the Genome<\/h2>\n

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 half is selected with the same attention as the female.<\/p>\n

A male passes on growth habit, hybrid vigour, flowering time, tolerance to mould and pests, trichome density and the terpene profile just as the female does; it just expresses some of those traits less since it does not produce a smokable flower. Those who work with regular seed invest as much time selecting males as females, which is the effort that a feminized line inherits and cannot replicate. Feminizing a female gives pollen; it does not provide a second line of selected traits.<\/p>\n

The Narrowing<\/h2>\n

A great deal of the feminized market is made from S1 seeds: a single popular clone, reversed and crossed with itself. Each round of that selfing cuts in half the surviving genetic variation, and after a couple of rounds what remains is essentially one plant repeated in marginally different ways.<\/p>\n

This is acceptable for a consumer who wants that single plant. It is a problem for everyone who comes after. Recessive faults surface: hermaphrodite tendencies, brittle stems, susceptibility to a particular mould. Qualities that existed in the parent line but absent in the chosen clone vanish from the gene pool altogether. A decade of such breeding leaves a market crowded with variations of the same few clones, and a breeder wanting to make something new finds there is little left to cross. Regular seed from a true outcrossed line is the store that replenishes the pool, and it can only persist if people keep growing it.<\/p>\n

Reading a Male Plant<\/h2>\n

Articles on selecting females are everywhere; guidance on choosing males is rare, since most growers never keep one long enough to look. For a grower producing seed, these are the marks breeders look for.<\/p>\n

    \n
  • Restraint.<\/strong> Plants that release huge quantities of pollen early are frequently also the least selected in other respects; many breeders favour moderate producers.<\/li>\n
  • Timing.<\/strong> A male that declares sex early and flowers at the same pace as the females is more workable than an early one that releases pollen before the female is ready.<\/li>\n
  • Stability.<\/strong> A male that at the same time forms female flowers under ordinary conditions is rejected without exception; that tendency is the last thing worth carrying into a line.<\/li>\n
  • Structure.<\/strong> Short internodes, a strong main stem and branching that matches the intended female habit are inherited; a lanky, weak-stemmed male passes that down too.<\/li>\n
  • Resin on the stem.<\/strong> Scratch a stem or a pollen sac and smell it. A male with trichomes on its sepals and a strong scent indicates it holds the resin genes worth passing on.<\/li>\n<\/ul>\n

    Thinking in Numbers<\/h2>\n

    A mistake first-time regular-seed growers make is treating a pack as 10 attempts at the same plant. It is nothing of the kind. A pack from a real outcrossed line is a slice of a population, and the point of running it is to see the range and choose from it.<\/p>\n

    About half the plants will be male, so a pack of 10 seeds gives something like five females to compare and five males to either discard or judge for breeding. Among the females, look for real differences: height, flowering time, smell, bud structure, tolerance. That spread is not a flaw in the seed; it is what the seed is selling. The grower who keeps the strongest female and male now owns something a feminized pack cannot supply: a pair of chosen parents that are theirs.<\/p>\n

    Three Ways to Cross<\/h2>\n

    Holding chosen parents means producing the next generation, and here the options multiply. The main methods account for most of what small-scale breeders do.<\/p>\n

      \n
    • Backcross.<\/strong> Cross a chosen seedling again to one of its original parents to lock in a particular trait. It tightens the genetics fast and is used when one plant shows something worth concentrating and the other contributed mainly vigour.<\/li>\n
    • Open pollination.<\/strong> Allow each male pollinate every female. It keeps the whole range of the line, makes a generous quantity of seed, and does no selection at all. This is how traditional lines are kept alive, and it is the correct approach when the goal is preservation not refinement.<\/li>\n
    • Selected cross.<\/strong> One chosen male on one or a few picked females, every other plant else culled. The seeds carry the qualities of the two selected plants and express less variation than the original pack. Done over generations with stable choices, this is how a stable line is built.<\/li>\n<\/ul>\n

      Each of these require only a separate space for the male, a paintbrush or a paper bag, and patience. Not one of them calls for the chemical reversal that feminized production does.<\/p>\n

      Landraces and Heirloom Lines<\/h2>\n

      Some lines have never feminized and probably never will be: landraces collected from places where cannabis grew over centuries, and heirloom crosses from the first decades of modern breeding. They are sold as regular seed since the people maintaining them regard the population as the entire value, and reversing a single clone would erase precisely what makes the line worth preserving.<\/p>\n

      Running a landrace from regular seed is a different experience from growing a modern hybrid. Expect large variation, long flowering times in tropical lines, lanky plants, and qualities that made sense in a field but not under a small room. There will be too flavours and chemistry that no longer exist in the commercial market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, and each line marked with its origin of origin and the number of generations it has been grown out from the original collection.<\/p>\n

      When the Library Is the Wrong Shop<\/h2>\n

      Nothing of the above makes regular seed into the right choice for everyone, and pretending otherwise does the product no service.<\/p>\n

      A grower with room for a handful of plants who needs each one of them to flower is far better served with feminized seed. The same is anyone unable to check the plants each day during the onset of flower, because a late male in a confined space ruins everything inside days. Someone running a single autoflower on a balcony gets no use from a population they cannot select from. And anyone who wants a known famous plant repeated as closely as possible is looking for a feminized S1, not a two-parent 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 safely left alone.<\/p>\n

      Before You Buy<\/h2>\n

      Breeder Regular Seeds sends each order in unmarked parcels with the breeder’s packs intact inside and no on the exterior to reveal the contents. Orders to the United States are not taken, because seed import is restricted there. Seed law varies widely by country: in a good number of places owning seeds is legal as genetic preservation while germinating them is not, and in others both are permitted under local rules or both is. Checking the rules in your own jurisdiction is the buyer’s responsibility, and no part of this article is legal advice.<\/p>\n","protected":false},"excerpt":{"rendered":"
