Evaluation of Soybean Varieties and Exotic Germplasm for Tolerance to Soil Waterlogging (2008)
Dr. Grover Shannon (Project PI), with the University of Missouri-Columbia, has been awarded a grant from the SSRP to find the highest performing soybean varieties in relation to tolerance to soil waterlogging.
Three objectives are hoped to be derived from this project:
It is important to minimize hazards soybean growers face. Growers who receive heavy rain after irrigation or in low areas or poorly drained fields often face excess water problems and crop injury. Yield loss to soil waterlogging can be 80 to 90%. Croup III, IV and V varieties dominate the majority of the Southern US acreage. Over a three year period (2002-2004), we identified a few group III0V soybean varieties showed better tolerance to field waterlogging than others. The most tolerant strains showed less yield loss (40%) than intolerant varieties (80%). New varieties since 2004 have been developed and released, but little is known about their ability to stand excess water. Exotic plant introductions could offer breeding material higher tolerance than is shown in current varieties. Identification of soybean varieties and exotic germplasm with greater tolerance to soil waterlogging will provide growers options to reduce field losses to excess water. Tolerant germplasm can be used in breeding programs to improve varieties for higher tolerance to waterlogging than is present in today's cultivars.

Three objectives are hoped to be derived from this project:
1. To determine the tolerance to field waterlogging among group III, IV and V soybean varieties and exotic germplasm lines.
2. Identify the most tolerant soybean varieties and germplasm lines and to determine levels of tolerance.
3. Provide information to soybean producers to select best varieties for waterlogging.
