Yield depends on superiority of the varieties planted, on the environment and on the pathogens that may threaten the plant species. Iowa is one of the main producers of soybean in the U.S. To protect yield, the state income, and food production it is necessary to protect the soybeans from pathogens that act as yield suppressants. Need 1: Genetic resistance in soybean cultivars; Need 2. Increase genetic diversity; Need 3. Identify new resistance genes for protecting soybean yields; bring new genes into the soybean commodity.
1. Develop high yielding cultivars. 2. Release new sources of resistance to Phytophthora root rot (PRR), Brown Stem Rot (BSR), Soybean Cyst Nematode (SCN), Sudden Death Syndrome (SDS), Iron-deficiency chlorosis (IDC).
The past year's accomplishments include the release of ten advanced high-yield experimental lines; one BSR-resistant cultivar; seven experimental lines were evaluated in the 2nd year US regional tests and advanced; and five experimental lines tested in the 2nd year US regional SCN tests; 30 advanced experimental lines were advanced in the 1st year US regional tests and 42 in the 1st year US regional SCN yield tests. Three SCN and 3 non-SCN test varieties were evaluated throughout Iowa.
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
