Table 6 Sorensen coefficients calculated on comparisons withina potato genotypes (control, chemical treatment) and betweenb potato genotypes for each individual year (2013, 2014 and 2015) and total during the 3 years for nematode families and genus identified from study completed at Oak Park (Carlow, Ireland)

From: A temporal assessment of nematode community structure and diversity in the rhizosphere of cisgenic Phytophthora infestans-resistant potatoes
