ENHANCEMENT OF COLD TOLERANCE IN SORGHUMS
Plant Stress and Germplasm Development Research
2013 Annual Report
1a.Objectives (from AD-416):
To cooperatively engage in the pursuit of breeding for enhanced abiotic stress tolerance in sorghum, which encompasses (but is not limited to) controlled environment and field screening of select sorghum germplasm in spring trials and statistical analysis and summarization of results.
1b.Approach (from AD-416):
1. Perform controlled environment screening for early season cold tolerance on select 60 Kaoliang lines (Chinese sorghum landraces). Confirm laboratory results on 60 Kaoliang lines with field evaluation through early season planting in Spring 2013 (April or May planting) in Ames, Iowa.
2. Conduct early season planting and controlled screening for various genetic stocks/lines (RILs, germplasm/landraces, select hybrids and checks in replicated trials) from the cold tolerance enhancement project developed at USDA-ARS Lubbock, TX, and Kansas State University.
3. Perform statistical analysis and documentation (in the form of graphs, photos, etc.) of results.
4. Provide the ARS coordinator with data, documentation (photographs or graphs),and report from the endeavors for use in preparation of reports to funding agency.
Controlled environment screening for early season cold tolerance of F1 hybrids between elite and Chinese parents was initiated in the laboratory. However field evaluation was halted because the cooperative agreement ended before the test was set up and due to prevalence of inclement weather and high amount of precipitation in the area. Field evaluation through early season planting in Spring 2013 (April 2013) was performed in Lubbock, TX, instead of Iowa for 2013.
