The objective of the research was to obtain information on genetic control of seed soybean storability. The research was conducted at seed testing laboratorium of Department of Agronomy and Horticulture (Bogor Agricultural University), Bogor, Indonesia. Genetic material used were 3 national varieties and 17 advanced breeding lines. The research was arranged in randomized completely block design with three replications. Black soybean seeds are stored in airtight plastic packaging at a temperature of 27–30°C and 57–60% RH for a 14 weeks. The results showed that all characters observed was significantly affected by genotypes. Traits related to seed storability are affected by genetic factors. All traits observed showed a high heritability. There is possiblity to improve seed soybean storabilty by breeding program. Based on growth rate of seedling and vigor index, SSD-10, SSD-17, SSD-18, SSD-39, SSD-82, SSD-91 dan SC-39- are the best seed storaability.
