TABLE 3.

Effect of the plant species on the EPC indexes as a function of the Rlv Nod types, Nod groups, or genospecies in pea (cv Kayanne and Isard) and lentil (cv Anicia, Rosana and Flora) associated with the Rlv core collection.

Kruskal Wallis tests were performed to estimate whether bacterial categories were equivalent (Ho hypothesis). P-value are indicated when significant effects of the genospecies, the Nod type or the Nod group on the EPC index were identified (p-value threshold= 0,05; ‘n.s’ not significant). Post-hoc Dunn pairwise test (with Bonferroni correction for multiple testing) were performed to identify bacterial categories displaying relative differences as indicated by italic letters (a_i, b_i, c_i, d_i).
