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. In addition to its suitability for tablestock, 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.
