Abstract

Abstract

Of eight soybean cultivars tested ‘Pickett’ and ‘Dyer’, were found to be resistant to the reinform nematode, Rotylenchulus reniformis. In the presence of Pickett and Dyer, the soil counts of renifonni nematodes were significantly reduced from an initial 10,000 larvae to less than 500 per pot over a 2.5-month period. Cultivars resistant to the root knot, Meloidogyne spp., did not possess resistance to the reniform nematode but those resistant to the soybean cyst nematodes, Heterodera glycines, did. Under the conditions of the test, the seed yields of Pickett increased while those of ‘Hood’ decreased when inoculated with reniform nematodes.
