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.

Brodie，一种双用途切片和餐桌品种，对金包囊线虫致病型 Ro1 和 Ro2 具有抗性，对淡包囊线虫致病型 Pa2/3 具有部分抗性

摘要

Brodie是一个高产白肉马铃薯品种，对金胞囊线虫（Globodera rostochiensis）Ro1和Ro2病型均具有抗性，对苍白胞囊线虫（G. pallida）Pa2/3病型具有部分抗性。它是1998年在康奈尔大学选育的康奈尔育种克隆NY121和NY115杂交而成，并于2018年由纽约农业实验站发布。块茎呈椭圆形，略扁，眼浅，表皮光滑诱人。除了适合餐桌原料外，Brodie 还具有切片的优点，因为其切片颜色良好，在 6.7 °C 储存两到四个月后切片后的亮度可与切片品种 Snowden 相媲美。在美国东北部的 63 项试验中，布罗迪的比重平均为 1.078，比同一地点的大西洋的比重低 0.010，而在纽约和宾夕法尼亚州的 70 项试验中，可销售产量平均为大西洋的 115%。对于受金线虫 Ro1 和 Ro2 致病型影响的种植者，Brodie 提供了一种生产适销作物的方法，同时降低 Ro1 和 Ro2 的侵染水平。
