Long time flowering recessive or dominant trait

[elcippe]

Guys I would like to cross a long flowering landrance and a short flowering one, does anyone know if long time flowering period is a dominant trait? My desire is to make a short period flowering plant.
The dominance could be also depending by the strain and not by the trait?
I hope this thread isn't already been created

The first seed harvested will yield plants from each strain. You will get some long flowering and some short flowering plants split in whatever ratio the grow gives you. Both strains will stay separate and not combine genetics with the first pollination. Combining genetics it takes many pollinations for the plants to combine into one.

Oh interesting thanks i didn't knew that, more or less on witch F should i see mixed genetics?

I don't know because it takes many pollinations and generations to mix genetics. Your first seed batch will be close to the mothers. Both mothers will show up individually in their own seed. You will get two seeds back from the first pollination. The two plants you cross will give two types of seed in the first seed harvest. They won't be mixed genetically on the first run.

Basically not what ^ said. Do u even grow bro

Interesting thanks. Do you know why is not like Mendel laws?

From what i've observed from other growers is that a longer flowering parent crossed with a short flowering parent can result in seed that isn't quite as long flowering as the long-flowering parent. How much time is shortened depends on multiple factors. But, you still may find seed that is as long or short flowering as either partent, also.

Oh ok good good thanks

Mendel certainly didn't (couldn't?) figure out all the genetics facts that we have discovered up to this time. Technology has helped with us finding more information, such as the higher resolution microscopes. Many things have advanced since Mendel's time. Think of how things have advanced since the original light bulb!

There are several genes responsible for flowering time.

So it's not so much a conflict with Mendel but rather just not a simple single gene trait like autoflowering or blue eyes.

 

[troutman]

Flowering time can be either dominant or recessive like so many other traits.
Two dominant plants crossed together will breed true for certain traits. It's the
same thing if you cross two recessive plants. They'll produce mostly plants with
recessive traits. I seriously doubt any healthy plant is either 100% dominant or
recessive.

In the end, it's all up to the breeder to select what is desired.

Hint: Grow as many plants and search F2's.

This pic may help you visualize a breeder creating an Auto.

Ok Thanks guys for the clarifications

Don't forget, "Long" and "Short" flowering in this context is for Sinsemilla plants.

Sinsemilla is a Human invention, not the natural state of the plant.

Would be interesting to study the flower period when the plants are naturally pollinated.
