Abstract
Soybean cultivars representing maturity groups 1-X were compared for their susceptibility to Pratylenchus scribneri under greenhouse conditions. A preliminary screening of 51 cultivars indicated a relatively wide range of susceptibility. Reevaluation of 12 of the cultivars con firmed that Clark 63, Woodworth and Williams are highly susceptible. Amsoy 71, Bonus, Corsoy, Jupiter and Wayne supported only limited reproduction. Custer, Dyer and Forrest, resistant to other nematodes, also appeared to be resistant to P. scribneri, while PI 88788 was intermediate in susceptibility. In comparison to other cultivars, Corsoy was the most intolerant of infection because growth was poorest and the density of nematodes in the roots was high.Downloads
