Kalyseeds form polyploid varieties. I'm afraid I'm going to ruin my genetics. When a polyploid crosses with a diploid, it produces seeds, but what ploidy will these seeds be? When you read about polyploidy in plants, within one plant species, when a population multiplies chromosome sets, it is infertile with diploids - this is how new species are created. And people didn't even know it for a long time until they started examining DNA.
For example, Tripleurospermum inodorum occurs as diploid (2n = 2x = 18) or tetraploid (2n = 4x = 36), sometimes as their triploid hybrid (2n = 3x = 27) which is usually infertile. So it seems to me that Tetraploids and diploids probably can't exchange genes as if they were two different species. But I don't want this to take place in my breeding program. (No matter how important)
However, the resulting triploids often have a reason
unbalanced number of chromosomes reduced viability and also higher infertility rates.
But if they maintain a certain degree of fertility, when are they
able to produce euploid (n, 2n or 3n) gametes, they can subsequently cross-cross with diploid or other triploid individuals to produce tetraploid progeny.
This process, in which the transition from diploidy to tetraploidy takes place, is
called a "triploid bridge"
Can anyone help me explain what ploidy is for Kalyseeds strains? And what does this mean for small breeders and their bred lines if they are contaminated with polyploid pollen? Thank you very much.
