This research was carried out with the objective to evaluated the physiological
seed quality of ten soybean genotypes: BRSMG - Garantia, MGBR-46 (Conquista), MGBR 94-
7916, FT-104, CAC-1, MGBR 95-19125, BRSMG - 68 (Vencedora), UFV-16, BR 94-12773,
Doko, from the 99/2000 crop year. The seeds were conditioned in cotton bags and stored in
uncontrolled conditions in Alegre in the State of Espirito Santo, during eight month. The
experimental design utilizated was the completely randomized, with four replications of 25 seeds,
in a 10x9 factorial. After harvest the genotype initial seeds moisture content was adjusted to
approximately 12%. The physiological seed quality were evaluated immediately, after the bigining
of the experiment and monthly, through the germination and vigor (first germination count) tests
and the seed health through the Blotter test. The results indicate that the cultivar Doko mantained
greater level of germination and vigor during storage and after 210 days of storage, the genotypes
presented null vigor and little germination, culminated approximately with 100% of deterioration
after 240 days of storage.
