Evaluation of perennial Glycine species for resistance to P. penetrans

The Bartlett test for homogeneity of variance was significant (P <0.05) between trials so data were analyzed separately (Table 4). For both trials, none of the perennial Glycine species showed reduced infection compared with the soybean varieties. For trial 1, G. clandestina PI 440960 and G. tomentella PI 339655 had significantly more nematodes per gram of root than cv. Lee 68, which had an average of 8 nematodes per gram of root. For trial 2, no accessions were significantly different from cv. Lee 68.
