Brodie, a dual-purpose chipping and tablestock variety with resistance to pathotypes Ro1 and Ro2 of the golden cyst nematode and partial resistance to pathotype Pa2/3 of the pale cyst nematode. American Journal of Potato Research. 101, 45-51. https://doi.org/10.1007/s12230-023-09939-x. DOI: https://doi.org/10.1007/s12230-023-09939-x Interpretive Summary: Brodie is a high-yielding potato cultivar with white flesh and oblong tubers. It was released by the New York Agricultural Experiment Station in 2018. Brodie is a tablestock cultivar but is also suitable for chipping because of its light fry color. Brodie has moderate resistance to early blight, late blight, and powdery scab. Most importantly, Brodie exhibits resistance to both Ro1 and Ro2 races of the golden nematode as well as partial resistance to the pale cyst nematode. Both the golden nematode and the pale cyst nematode are regulated pests present in New York and Idaho, respectively. Because of its novel nematode resistance, for NY growers having the golden nematode problem in their fields, Brodie not only offers a means of producing a marketable crop but also helps to keep the quarantine nematode under control. Technical Abstract: Brodie is a high-yielding white-fleshed potato cultivar with resistance to both pathotypes Ro1 and Ro2 of the golden cyst nematode (Globodera rostochiensis) and partial resistance to pathotype Pa2/3 of the pale cyst nematode (G. pallida). It was selected from a cross made at Cornell University in 1998 between Cornell breeding clones NY121 and NY115 and released by the New York Agricultural Experiment Station in 2018. The tubers are oval and slightly flattened, with shallow eyes and smooth attractive skin. Brodie also has merit for chipping as its chip color is good, comparable in lightness to the chipping cultivar Snowden when chipped out of two to four months of 6.7'C storage. Specific gravity of Brodie averaged 1.078 across 63 Northeastern US trials, 0.010 less than Atlantic in the same locations, while marketable yield averaged 115% of Atlantic across 70 trials in New York and Pennsylvania. For growers affected by pathotypes Ro1 and Ro2 of the golden nematode, Brodie provides a means of producing a marketable crop while simultaneously decreasing infestation levels of both Ro1 and Ro2. |
