Evaluation of perennial Glycine species for resistance to R. reniformis

The Bartlett test for homogeneity of variance was not significant (P> 0.05) between trials so data were pooled for analysis (Table 3). The perennial Glycine species and soybean checks differed in their response to R. reniformis based on the number of eggs and vermiform nematodes per gram of root. The mean number of R. reniformis per gram of root on susceptible check PI 88788 was significantly higher than that of resistant check cv. Forrest. In contrast to M. incognita, some perennial Glycine accessions (PIs 505188, 505214, 505238, 509487, 559298, and 573045) were significantly more susceptible to R. reniformis than the susceptible check PI 88788. Only G. tomentella PI 441001 had a significantly lower number of R. reniformis per gram of root than cv. Forrest.
