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.
