Potato breeding is a long and slow process. It can take years to develop a new variety of potato, and even then, there is no guarantee that it will be successful.
One of the biggest challenges in potato breeding is that it is difficult to cross tetraploid potatoes with diploid potatoes. Tetraploid potatoes have twice the number of chromosomes as diploid potatoes, and this can make it difficult for the chromosomes to pair up during reproduction.
The researchers at Wageningen University and Research have found a way to overcome this challenge. They have discovered that the Sli gene, which is responsible for self-compatibility in diploid potatoes, is also present in tetraploid potatoes. This means that tetraploid potatoes can now be crossed with diploid parents to transmit their fixed set of traits.
This is a major breakthrough for potato breeding. It could significantly speed up the process of developing new varieties of potatoes, and it could also lead to the development of new varieties that are more resistant to disease and pests.
The researchers are now working to develop new varieties of potatoes using this new technique. They are also working to make the technique more widely available to potato breeders.
This gene discovery is a major step forward for potato breeding. It could help to ensure that the world has a reliable supply of potatoes for years to come.
