Conteúdo: | Soybean cyst nematode (Heterodera glycines Ichinoe) is one of the main problem causing yield losses in Brazil. In this study 195 soybean inbred lines were screened against H. glycines race 14. The germplasm was originated from a soybean breeding program in Goiás State, Brazil, in a partnership among EMBRAPA, AGENCIARURAL and CENTRO TECNOLOGICO PARA PESQUISA AGROPECUÁRIA-CTPA. The differentials, 'Peking', 'Pickett', 'PI 88788', 'PI 90763', 'PI 437654' and the susceptible varieties 'Lee 74' and 'EMGOPA 314' were planted together in the same set in order to verify the race identification. Besides the differentials, the resistant varieties 'BRSGO Chapadões' and 'Hartwig' were also planted. For each treatment (total of 205) a set of 8 replications was pre-germinated in paper towel for 48 hours and the seedlings were transplanted into a 200 cc soil pot containing an average of 78 cysts per 100 cc of soil. Thirty five days after transplanting, all the white and the yellow females on the roots were counted and the results classified as resistant or susceptible according to the race scheme described by Riggs and Schimitt (1988). The race test confirmed the H. glycines to be race 14. Most of inbred lines tested were susceptible and only 6 inbred lines were resistant as follow: GOBR99-626036, GOBR99-689021, GOBR99-634012, GOBR99-689037, GOBR99-155033 and BRAS99-14068. The resistant varieties used as checker were 'Hartwig' and 'BRSGO Chapadões', which confirmed their resistance to race 14. The resistant inbred lines will be screened for agronomical traits in field trials for at least two years, before they are recommended as new soybean cyst nematode resistant varieties for the market.
