Fixation: Self-fertilizing diploid potato will make the two copies of each chromosome
progressively identical. Restitution: Inbreeding depression can be avoided by crossing partially
fixed diploids with tetraploids. Image courtesy of Wageningen University & Research.
efficiency of self-fertilization and aim
for fixation of an important set of genes
while avoiding the loss of vigor that
comes with repetitive inbreeding. In
the restitution step, all fixed genes are
shuttled to tetraploid elite clones using
unreduced pollen.
Clot recently defended his thesis
and plans to continue postdoctoral
research with the same group of
scientists at WUR.
" Now we can use the markers I
developed for self-compatibility and
unreduced pollen in our diploid
breeding program, so we can make the
'fixation-restitution' breeding scheme a
reality, " he said.
Clot is also collaborating with
breeding companies to translate his
research into practical applications.
Initially, he'd like to do a proof-ofconcept
study using resistance genes.
" I see great potential for resistance
breeding, because with classical potato
breeding, it takes 10-12 years to bring a
new resistance gene into a new variety,
while little effort is put into stacking
resistance genes before bringing them
to the market, " Clot said.
This is especially problematic for fastevolving
pathogens like Phytophthora
infestans (the causal agent of potato
late blight), which can rapidly overcome
single-resistance genes.
" Our idea will be to combine and fix
as many resistance genes as possible in a
diploid plant and then shuttle them all
at once to the tetraploid level, "
Clot said.
A successful result would be a
realistic, efficient way to breed better
potato varieties that could get more
robust varieties into the hands of
growers faster.

Wageningen, Netherlands, related to potato sexual reproduction could simplify breeding.
