ARS Scientists Develop Drought-Hardy Soybean Lines
November 7, 2008| |
Scientists from the US Department of Agriculture’s Agricultural Research Service (ARS) will soon release advanced soybean breeding lines that carry slow-wilting traits. Field trials have demonstrated that the new soybean varieties perform well under drought conditions, and also show good yield when rainfall is plentiful. The slow-wilting lines yield 4 to 8 bushels more than conventional varieties under drought conditions, depending on the region and environment.
The new soybean lines were developed by ‘Team Drought’, a group of researchers at five universities led by ARS plant geneticist Thomas Carter. For more than 25 years, Carter has been working on transferring slow-wilting characteristics from Asian landraces, which are foreign "introductions," into U.S.-adapted varieties.
Using conventional breeding methods, Carter and his team develop hundreds of new breeding lines each year, for a total of more than 5,000. The scientists have identified five soybean lines that consistently stand up to drought.
