Abstract: During 2004, 194 soybean varieties from the Arkansas variety testing program, 34 Clemson and 8 Arkansas breeding lines were tested in the greenhouse to determine their suitability as hosts for the reniform nematode (RN), Rotylenchulus reniformis. All treatments were inoculated with 1,200 vermiform RN. The resistant varieties Forrest and Hartwig, RN susceptible Braxton, and RN fallow soil served as controls. The mean number of vermiform nematodes extracted from the soil of each treatment was calculated, as were the reproductive indices (RI = Pf/Pi), PI/PI of Forrest (RF), and PI/PI of Hartwig (RH). Varieties with RF=s significantly greater than the RF on Forrest (1.00) were considered suitable hosts for R. reniformis. Of the Arkansas test varieties 183 of 194 had more RN reproduction than Forrest whereas 189 lines, including Forrest, had more RN reproduction than Hartwig. The following varieties were not different than Forrest; Delta King XTJ54X9, S02-611RR, HBK R4945CX, Hartwig, S00-9970-08, S00-9970-09, Southern States RT5730N, DT98-7278, Southern States RT5602N, FFR 5663RR, Terral TVX56R405, and ARX E57104, whereas only Delta King XTJ54X9, S02-611RR, HBK R4945CX, S00-9970-08, S00-9970-09 were not different than Hartwig. On 22 of the 34 Clemson breeding lines RN reproduced more than on Forrest, while on 33 RN reproduced more than on Hartwig. On all of the Arkansas breeding lines RN reproduced more than on either Forrest or Hartwig.
