KDH13 is a doubled haploid pure genetic stock produced via unfertilized ovule culture. This genetic stock originated from C762-17 (PI560130). C762-17 was developed by USDA-ARS and released in 1989 as beet curly top resistant parental line, but it exhibits a degree of genetic variability and segregates for genetic male sterility. A single selfed (S1) plant from C762-17 was used as a donor of floral buds for tissue culture. Different explants were tested, but only ovule culture was successful. KDH13 is confirmed a diploid by flow cytometry.
KDH13 is the first publically available sugarbeet genetic stock that is produced via tissue culture. This genetic stock is highly resistant to beet curly top caused by Beet curly top virus, Beet mild curly top virus, and Beet severe curly top virus which are transmitted by the beet leaf hopper (Circulifer tenellus). It performed better than the resistant check in two greenhouse experiments and same as the resistant check in one field screening in the curly top nursery in Kimberly, ID. KDH13 has light green, upright, narrow leaves, and small compact canopy. It is susceptible to powdery mildew caused by (Erysiphe polygoni). KDH13 can be an ideal curly top resistance donor parent in hybrids, backcrossing, and inheritance studies and other economically important traits. KDH13 is a monogerm, self- fertile, and resistant to bolting. The initial ovule culture work was carried-out under contract by a private company. KDH13 developed by the sugarbeet group of the NWISRL, Kimberly, Idaho.
