How to hybridize a plant: instructions for crossing two plants and creating the most suitable hybrids for your needs.

Gardening enthusiasts reaching one more stageevolved, may ask questions about theplant hybridization or more simply, onhow to cross between plants. In this guide we will explainhow to hybridize a plantand the same instructions can be used for crossing chilli plants as well as for hybridizing roses or orchids.

Hybrid plants, what are they

Hybrid plants are the result of across between seedsto obtain certain characteristics. Generally speaking ofF1 hybrid plantsto identify the first generation of a cross between two different species or botanical varieties.

With the'plant hybridizationtwo reproductive lines of the same species are used (called pure lines) which differ in particular characteristics.

The two breeding lines are grown for several generations, sowing after sowing, in two separate places to avoidgenetic contamination. At each generation, two lines are selected within the population of cultivated plants for the same sought-after "character".

In this paragraph we will seehow to create plant hybridscrossing two different species ofPhalaenopsis. The same technique asplant hybridizationthat we will see in this paragraph can be applied forcross pepper plants, forhybridize rosesor cross two plants.

Pure lines

To get an F1 hybrid with the characteristics you want"to preserve", remember that you have to take genetic material (pollen) from pure lines. You can get pure lines with a large number of crosses between plants with the same characteristics or by contacting a specialized nursery. The same technique can also be applied with plants that are not "pure lines". If you use plants not selected from pure lines, the variability of genetic expression will most likely not give you the desired result.

Artificial pollination

It starts with a "manual pollination". In practice you have to withdraw thepollenfrom one species and deposit them, with great precision, in the flower of the second plant.

Depending on the species in question, to collect the pollen you may need a stick, a tube or a precision pliers, only for some species, those with the most abundant pollen, you can use the brush.

For plants such as orchids or hot peppers, probes and precision pliers may be more suitable for both collecting pollen and manually pollination. To get an idea of ​​what you need, I invite you to consult the two Amazon pages with useful tools forpollinationdo it yourself forhybridize plants.

During flowering, take pollen from one plant and place it in the second plant's flower. If thepollinationwas successful, a capsule will form containing the new seeds.

In the case of the orchid, just blow, very gently, on the capsule to collect the seeds on a napkin.

Let the resulting crosses sprout

In the laboratory, plants must always be kept separate from each other and in contamination-free environments: only in this way can you be sure that it was your pollen that fertilized the flower of the second plant!

The seeds collected, always in the laboratory, are sprouted in an incubator, suspended in a gel substrate. In the home, you can germinate the new seeds in any seedbed. Sprout the seeds and transplant yourshybrid plantswhen they are sufficiently developed.

Among the various seeds germinated, select the plants that have the desired characteristics to make new crosses.
