| reaction of selected soybean cultivars to rhizoctonia root rot and other damping-off disease agents. | eight soybean cultivars; giza 21. giza 22, giza 35, giza 82, giza 83, crawford, holladay and toamo were evaluated to rhizoctonia root rot using agar plate and potted plant techniques. data cleared that, in agar plate assay all soybean cultivars were moderately susceptible (ms), although the differences between them were significant (p=0.05). generally, in potted assay, the reactions were resistant (r) or moderately resistant (mr) to root rots. also, the differences between cultivars were signifi ... | 2005 | 16637203 |
