Other claims from this paper (9)

Method / resource Seinhorst population models fitted resistant potato genotype data well except one genotype that lacked resistance.
Recommendation The study suggests that the number of nematode densities used in resistance tests can be reduced.
Method / resource The population dynamical model fitted the tested potato genotypes well.
Association Maximum population density decreased as potato test pot size increased.
Observation Estimated rsa values were relatively stable across potato test pot sizes.
Observation Estimated rsM values were a bit higher in 5 kg potato test pots.
Method / resource Seinhorst yield models fitted fresh potato tuber weight well.
Observation Root knot index values were stable across the three potato test pot sizes.
Recommendation The authors conclude that potato resistance tests for M. chitwoodi can use smaller pots and fewer nematode densities.
