2012 Annual Report
This is the final year of the cooperative Karnal Bunt field screening project in India. Many wheat lines that showed resistance in previous years again showed moderate to good resistance in the 2012 nursery. A doubled haploid mapping population between a source of very high resistance and a susceptible line was evaluated for the fourth year. This population will be genotyped in the coming year by ARS researchers in Manhattan, KS. Data will be analyzed to find the locations of resistance genes for Karnal Bunt. A backcrossing program using Jagger as the recurrent parent is at the fourth backcross generation. We now have a derivative of Jagger with very good agronomic type and very good resistance to Karnal Bunt.
