f1 hybrid weed seeds

A recombination does happen between two corresponding chromosomes and, because there is no un-linkage of alleles, there is just a recombination with its identical copy. Therefore, the traits of the chromosomes stay linked, producing the desired set of traits on the chromosomes and resulting in an F1 hybrid.

While it may be the simplest way, it usually involves removing all male plants from the population, which can still be time-consuming, but there are also other methods of achieving this. While it may be time-consuming, it is still one of the most commonly used methods in agriculture and plant breeding today. To give you an idea, ninety-nine percent of all corn plants, 80% of sunflowers, 95% of sugar beets and 60% of onions that are produced in the United States each year are strictly F1 hybrids.

F1 breeding first arose in the 19th century with the work of Gregor Mendel, the father of modern genetics. As an Austrian friar, he spent much of his day caring for plants, especially pea plants that were used to feed the friars of his order. His careful observance of the genetic patterns in the offspring of certain pea plants gave rise to his hypotheses of inheritance through generations that later became known as genetics.

What is a F1 Hybrid? Cannabis Genetics Explained

Traditionally, F1 hybrids have been used in agricultural crops and have been the driving force behind the study of agronomy. Cannabis Breeders have inbred plants for years to produce more desirable results. They use a process known as Heterosis to yield wanted characteristics in order to get not just one plant with the favorable traits but all produced plants with a uniform characteristic.

than simply letting two Marijuana Strains cross-pollinate, the basis for most plant breeding. To ensure that you do not get offspring that shows the traits of one dominant parent, scientists carefully control the pollination of Marijuana Strains.

True F1 hybrids are produced by controlled pollination which must be repeated each season. The controlled pollination is done by hand in carefully measured batches and given to the receiving plant in a very controlled environment in order to achieve this hybrid cross. This long process is the reason behind the higher prices of F1 hybrid seeds that you see on the market.

While simply controlled pollination can produce a true F1 hybrid, it often requires a specific plant breeding process in order to accomplish the exact desired traits in the offspring. Often this is done through the process of reverse breeding or Doubled Haploidy (DH). This helps to produce a homozygous plant from a heterozygous starting plant. This process creates doubled haploid cells from haploid cells which eliminate the need for genetic recombination.

This guide is written on the basis that we are crossing two different strains with one another, to make a new variety. Starting with regular seeds you will label each seedling to make the catalogue process simple and easy from the very start. You will be looking for a particular female that aligns with your criteria, as well as looking for male plants that from appearance, look similar in height, structure, leaf pattern and so on.

Once you have established the end result on paper and what traits you are bringing forward, then the way to sift through your regular seeds should be to look for those traits in the plants you will select from. Some breeders may only be able to work with a small space and growing over 20+ seeds at a time to find one keeper is not practical or logistical.

Desired Traits Over Non Desired Traits

Isolate the male plants from the females and label the plant dependant on the sex. At this point you will want to select the females you find the most appealing and pair them off with the male that you have chosen. If you have multiple males you will either need a second tent to perform the breeding process, or you must wait until the first male has flowered and begin new with a clean and sanitized room, at a later date.

STEP 6:

F1 stands for first generation lineage, and represents the offspring created by the original mother and father. The term is also an expression of a hybrid made using regular seeds. Female seeds are referred to as S1 and involve a completely different process than working with regular stock.
