The United States Department of Agriculture, Agricultural Research Service, announces the release of the soybean germplasm SBML1.
SBML1 germplasm consists of 146 recombinant inbred lines of soybeans derived from the hybridization of the plant introduction Pl290136 and BARC-2 (Rj4), a near isogenic line derived from the cultivar Clark63. These lines were developed by eight successive generations of inbreeding and approach homozygosity for most traits. Homozygous lines retain genetic stability through increased availability of this germplasm. They also enhance the soybean genome mapping program by permitting researchers at other locations to contribute information on these lines to the publicly available genetic database maintained by the Plant Molecular Biology Laboratory.
These recombinant inbred lines are being released to facilitate the genetic mapping of the soybean genome. They have been characterized for genes controlling bacterial pustule resistance, maturity, seed coat color, root fluorescence, flower color and resistance to nodulation by the chlorosis inducing species Bradyrhizobium elkanii. A database of molecular markers (RFLPs and RAPDs) is available, and researchers requesting seeds of the recombinant inbred lines are requested to add their data to this database.
Limited quantities of seeds of SBML1 are available after to researchers upon written request to T. E. Devine, Plant Molecular Biology Laboratory, Plant Sciences Institute, USDA, ARS, 10300 Baltimore Blvd., Beltsville, MD 20705. When this germplasm contributes to genome mapping research, it is requested that appropriate recognition be given to its source. Genetic material of this release will be deposited in the National Plant Germplasm System, where it will be available for research purposes.
