Table 2 Results for disease resistance category and genotype source comparisons for 29 chickpea genotypes for the variates of number of nodules/plant, number of nodules/g root, and ethylene production per nodule (ppm/g) for comparisons of a) Fusarium wilt (FW) disease resistance categories: moderately resistant (MR); resistant (R) and asymptomatic (AS); b) Phytophthora root rot (PRR) disease resistance categories: susceptible (S); moderately susceptible (MS), and moderately resistant (MR); and c) genotype source group of Indian (IND) and Australian genotypes (AUS). P values, standard error of differences (SED) and least significant difference (LSD) values
