Research Project: ENHANCEMENT OF COLD TOLERANCE IN SORGHUMS

Location: 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 encompass (but is not limited to) crossing and hybridization of select sorghum germplasm to elite inbred females of the KSU sorghum breeding program, perform spring trials, field day, statistical analysis and summarization of results.


1b.Approach (from AD-416):
1. Perform crossing and hybridization of select sorghum germplasm to elite inbred females of the KSU sorghum breeding program in 2012 and 2013 and provide F1 seeds to coordinator for use in implementation of the parent grant. 2. Conduct early season planting and controlled screening for select lines (germplasm/landraces, select hybrids and checks) and hybrids from the cold tolerance enhancement project developed at USDA-ARS Lubbock, Texas, and Kansas State University. 3. Cooperate and conduct a field day and outreach. 4. Perform statistical analysis and documentation (in the form of graphs, photos, etc.) of results and provide the ARS coordinator with data, documentation, and report from the endeavors of the agreement for use in submission of reports to funding agency.


3.Progress Report:

Genetic studies for combining ability of candidate B lines and hybrid performance through crosses with 2 set of KS female germplasm was accomplished. Results showed that hybrids exhibited consistent higher germination and strong vigor compared to parents and checks in field evaluation trials.
