Scientists from Wageningen University & Research (WUR) and inventor of hybrid potato breeding Solynta have published the most complete genome sequence for potatoes to date. A unique aspect is that both sequence and plant material are made available for research (under specific conditions). This may in the future result in a potato that is more resistant to heat or drought or has a greater resistance to diseases.
Improvements to the potato’s traits can therefore have a major impact. Reading the genome structure of the potato is extremely tricky, however, as a regular potato consists of four genomes, which makes it difficult to determine the position of the genes.
The recent research applied a diploid real potato plant with only one genome, a so-called homozygote, which makes it easier to read and compare the DNA base sequence. This plant, Solyntus, was produced as part of Solynta's hybrid potato breeding program.
