Abstract

Population increase of Pratylenchus hexincisus on 41 soybean cultivars (maturity groups I-VI) and lines was tested under greenhouse conditions. After 3 months, P. hexincisus was recovered from the roots of all plants tesled. Final populations of P. hexincisus per pot were larger than the initial population in 13 cultivars. Pathogenicity of P. hexincisus on five soybean cultivars representing maturity groups (I-V) was demonstrated under greenhouse conditions. An inoculmn of 5,000 P. hexineisus/plant significantly decreased the root and shoot biomass of all five soybean cultivars after 3 months. Key words: lesion nematode, resistant cultivar, ecology, pathogenicity.
