Table 5 Nematode diversity, as per richness (H), evenness (EH) and dominance (D, 1-D, 1/D) indices, arising from samples taken from under different potatoes genotypes (Desiree, cisgenic Desiree, Sarpo Mira) treated with different disease management (control, chemical treatment) through the years of 2013, 2014 and 2015 at Oak Park (Carlow, Ireland)

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