Research Project: SUGARBEET GERMPLASM DEVELOPMENT AND INNOVATIVE GENETIC AND MANAGEMENT APPROACHES TO REDUCING LOSSES CAUSED BY PATHOGENS

Location: Northwest Irrigation and Soils Research

2012 Annual Report


4. Accomplishments
1. Curly top resistant sugarbeet breeding line released. Public pure breeding lines in sugarbeet are rare but they are key to molecular genetics research. At Kimberly, Idaho, a doubled haploid line (DHL) was produced and released as a genetic stock (KDH13 = PI663862). KDH13 is highly resistant to the three curly top virus species found in U.S. sugarbeet. It can serve as a parental line for transferring curly top resistance gene(s) to varieties that lack this level of resistance.

2. Sugarbeet mutants generated to increase diversity for genetic research. A bottle neck in sugarbeet genetic diversity is eminent. Using the facilities of the International Atomic Energy Agency (IAEA-Vienna, Austria), germplasm from Kimberly, Idaho, sugarbeet program was irradiated with gamma-radiation to obtain more than a thousand mutants. These mutants will broaden the genetic resource available for identifying disease resistance and desirable traits.
