BEHAVIOR OF FIVE SOYBEAN CULTIVARS, UNDER DIFFERENT INOCULUM CONCENTRATION OF Heterodera glycines

Abstract

Sob diferentes concentrações de inóculo de Heterodera glycines, foi avaliado o comportamento das cultivares de soja ‘FT-Cristalina’, ‘EMGOPA-313’, 'FT-Estrela’, 'FT-Seriema’ e ‘Doko-RC’, recomendadas para o Estado de Goiás. O ensaio foi conduzido sob condições de casa de vegetação, na Escota de Agronomia - UFG, no município de Goiânia, GO (latitude 16°40'00" W, longitude 49°15’00” S, altitude 741,48 m) no período de janeiro a maio de 1996. O delineamento experimental adotado foi inteiramente casualizado, em esquema fatorial 5 x 4, com 4 repetições. A população de H. glycines, aos 110 dias após a semeadura, não foi influenciada pela cultivar de soja nem pela concentração inicial de inóculo. A ocorrência de temperaturas ambientes muito elevadas pode ter afetado a infestação do nematóide. PALAVRAS-CHAVE: Glycine max; Heterodera glycines; resistência; concentração de inóculo.

This study was carried out at Escola de Agronomia - UFG, under greenhouse conditions in Goiânia, GO (Lat. l6°40'00"; W, Long. 49°15'00"; S, Alt. 741.48m) from January to April, 1996. The purpose was to evaluate the behavior of ‘FT-Cristalina’, ‘EMGOPA-313’, 'FT-Estrela’, 'FT-Seriema’ and ‘Doko-RC’ soybean cultivars, under different inoculum concentrations of soybean cyst nematode Heterodera glycines. The experimental design was completely randomized, in factorial scheme 5 x 4, with four replications. The nematode population, 110 days after sowing, was not influenced by soybean cultivars and by inoculum concentration. High environmental temperature levels could have affected nematode infestation. KEY-WORDS: Glycine max; Heterodera glycines; resistence; inoculum concentration.
