Database Research Summaries2018 Breeding High Yielding Soybean Cultivars for Iowa Farmers
The focus of this project is to develop superior soybean cultivars for Iowa farmers. These cultivars will provide high yield and protection against biotic and abiotic factors to keep Iowa farmers competitive and profitable.
- Increase soybean seed yield using genomic and phenomic tools.
- Incorporate high yield and multiple yield protection traits using improved germplasm material.
- Establish and operate a marker-assisted selection breeding system and repository.
- Determine the plant traits in soybean for maximizing profitability in corn-soybean rotation, and complete seed density and row width studies.
- Survey for pathogens causing known and unknown diseases.
- The Chile nurseries were successful, and seed was received in time for normal planting in Iowa.
- New sources of resistance for disease resistance (including, soybean cyst nematode) and abiotic stresses were identified and used as parents in the 2017 crossing nurseries.
- Single plant selections were made in the breeding populations. Single plot selections were made in the short row plots for incorporation in yield tests.
- At the time of reporting, combine harvest is continuing but near completion; single plant pulls and pod picks have been completed. F1 seed of new populations, developed to meet our objectives, has been sent to Puerto Rico and Chile.
- This project will provide genetic solutions to Iowa farmers that meet their on-farm requirements and help improve profitability.
- This project will lead to development of cultivars that addresses their on-farm production issues and requirements; and the development of unique germplasm that will be desirable to private industry and indirectly benefit Iowa farmers.
