Summary
Soybean cyst nematode, Heterodera glycines Ichinohe, is one of the major phytopathological problems affecting soybeans, Glycine max (L.) Merr., in the major producing countries and the use of resistant cultivars and crop rotation have been the main methods of control adopted to reduce the nematode population in infested soils. Purpose of this study was to evaluate the effect of resistant (BRSGO Ipameri and BRSGO Chapadoes) and susceptible (BRSGO Aracu, BRSGO Jatai, BRSGO Luziania, BRS Favorita RR, BRS Valiosa RR, BRS Silvania RR) soybean cultivars on the development of H. glycines males and females during two successive years (2007 and 2008). In the trial of 2008 the plants were divided in three plots, with the last one having the roots stained to count the juveniles and to evaluate survival rate. Resistant cultivars always maintained a small number of females and males, except for cultivar BRSGO Ipameri that had a high count of males. Only cultivars BRS Favorita RR and BRS Silvania RR had a sex ratio of 1:1. All other susceptible cultivars had, in general, greater number of males than females. Survival rate was nil on both resistant cultivars, and varied from 6.75 to 35.00% on the susceptible cultivars.
