Variety Details



Whitney has attractive, uniform short-oval tubers with a beautiful bright skin and white flesh. Low dry matter with excellent boiling quality. Keeps its beautiful colour after storage. Whitney shows good resistance to common scab


When cutting bigger seed, suberization after cutting is highly recommended and preferably use dry seed piece treatment; better to avoid the use of liquid seed treatment.


Early maturing, medium size plants. Manage Nitrogen (N) applications carefully. Heavy Nitrogen fertilization will cause excessive foliage and rapid tuber bulking. It can cause internal brown spots, affecting the tuber quality.


To prevent brown flecks in the tubers, use cultural practices that promote steady, uniform growth rates and avoid stress conditions: schedule irrigation carefully during tuber bulking and avoid excessive irrigation; avoid excessive nutrient (N) application; avoid elevated night time temperatures particularly in sandy soils; supplementary fertilization with trace elements can be useful. Additional Magnesium, Calcium and Boron applications is recommended. Calcium fertilizers best to be placed in the zone of tuber formation and can be applied before or at planting, or side-dressing after planting. Magnesium and the micronutrient Boron should be applied at rates appropriate to meet normal growth requirements.
