Genetic Variability in the Cyst and Root-Knot Nematodes Grant uri icon

Overview

abstract

  • The following experiments will be conducted at the University of Idaho; Nematode laboratory to confirm is there any differences in the two geographically isolated populations of lesion nematode which are collected from potato fields. Two populations of lesion nematodes denoted as an Idaho population and Canadian population will be used in all the studies. The first experiment will prove is there any difference in the reproduction of two isolates on the potato. In the second experiment, reproduction rate of the above mentioned two populations of lesion nematodes will be determined on two potato varieties. Verticillium wilt is the disease caused by the fungus on potato. The severity of the disease will be increased in the presence of lesion nematode. Hence an experiment will be conducted to find out, is there any difference between the two lesion nematode populations in increasing the severity of the disease on potato. In the fourth experiment the yield loss on potato by the two populations of the lesion nematode will be determined. Four doses of the two populations of lesion nematode will be inoculated. At harvest, the data on foliage, root weight, tubers weight and nematode population will be counted. In the fifth experiment two new varieties of oil radish and white mustard on the management of sugar beet cyst nematode will be determined.
