The cultivated potato has four sets of chromosomes, which is called tetraploid.
In traditional potato breeding two heterozygous tetraploid cultivars are crossed.
It does not take much imagination to see that a heterozygous tetraploid crossing is extremely unpredictable, especially when one considers that potato genome has over 30,000 genes.
The development of a new cultivar of potato with a gene, introduced from a wild species by crossings and selections, takes 15 to 30 years.
One of the key elements in the Solynta breeding method is the development of diploid homozygous potato plants which can be used as parents (elite breeding line) to produce an F1 hybrid cultivar. In principle, this is done exactly the same as is done for years in many other crops, for example tomato. Up until the breakthrough by Solynta this was previously deemed impossible due to the severe inbreeding depression and self-incompatibility. Solynta has proven that these hurdles can be overcome and F1 potato hybrid cab be produced.
