Myths about landraces

By admin

Landraces are pure lines of cannabis that breeders use to develop new varieties. Landraces are often used to produce F1 generation hybrids with original properties and effects. Of course, it takes a lot of effort and patience for breeders to stabilize such hybrids, but the result is worth it!

The very notion of landraces is ambiguous. Some people think that landraces are necessarily Cannabis Sativa in the classical sense. That is, tall bushes up to 3 meters with narrow leaves and the traditional hovering. However, this view is fundamentally wrong. The main thing that distinguishes landraces is the autonomy of growth and development. You can find these genetically pure lines anywhere in the world – and the cannabis can be either pure Indica or pure Sativa. And you can also make maryland medical marijuanas card online.

What can be considered landraces?
Not all genetically pure lines growing in nature can be considered landrace, suitable for breeding work. You cannot call formerly cultivated plants that have become wild plants over time a landrace. True landrace is cannabis that has been growing in a particular area for many decades. Cannabis of the Indica or Sativa variety that has not been influenced by breeders and has grown in the natural conditions of a particular region. Landraces are named just after the region in which the pure genetic line was found – e.g. Mexican, Thai, Afghani, Columbian, etc.

Common myths about landraces
Myth #1: Landraces have a very long life cycle that is nothing compared to the development time of hybrids.

In fact. Part of the myth has a factual basis. Exaggeratedly long maturation is noted in landraces from the equatorial zone: for example, from the valleys of Thailand, South India and South Africa. When selecting these varieties, however, breeders try to select plants with a shorter flowering period and those that grow in the mountainous regions of the equatorial belt of each locality. As for landraces from other areas of the globe, their maturation period is no different from the life cycle of hybrids. And in the case of landraces from Afghanistan and Pakistan, they are even faster!

Myth #2: There is an opinion that landraces are “dirty”, “shredded” genetics, which are not stable under natural conditions.

In fact. Of course, if landraces from exotic countries in the equatorial belt are planted, for example, in natural conditions of temperate latitudes and left untended, the plants will quickly turn into hybrids. There is a high probability of genetic deterioration due to pollination by technical cannabis or wild ruderalis. Landraces from Afghanistan and Pakistan are much more resistant. They are more easily adapted to the conditions of the cool latitude outdoors.

Myth #3: Landraces don’t germinate regularly and are very difficult to germinate.

In fact. Yes, the facts say that this opinion has some basis in fact. Indeed, landraces germinate with difficulty, even in many cases it is necessary to prune the seed in order for the plants to still germinate. There are two reasons for this. First, the plant may trivially “wait” for the special climatic conditions in which it germinates in the natural conditions of its region. Secondly, the seeds have a thick shell.

Irregular germination in nature is a kind of protective reaction. For example, some plants may not germinate until several years after planting. In the natural environment, a thick seed coat helps maintain the population even when there is severe frost or drought. This is why breeding with pure landraces is always very difficult. Breeders spend years of work selecting and stabilizing the best examples of pure genetics! And that is exactly the kind of varieties and hybrids based on landraces that are offered by well-known producers.
