Variety Characteristics:
Nadine  is a vigorous mid-season variety with very high potential and good storage characteristics. It sets numerous round oval, uniform, bright white fleshed tubers suited to table consumption.

Unique disease resistance characteristics for Nadine includes: Resistance to golden nematode Ro1 and moderate resistance to pale cyst nematodes Pa2/3, common scab, bruising, Black leg and PVX. Nadine is resistant to PVY and requires a standard North American management program for late blight.

Nadine is widely adapted and demonstrates best performance were crops can acquire sufficient moisture throughout the growing cycle.


Seed Preparation:
Cold seed should be warmed to 10-15°C (50-60°F) to minimize bruising during handling.  Pre-warming may be necessary depending on the planting date, as Nadine has a average dormancy. Nadine can successfully be pre-cut. Optimum cut seed sizes are 50-gram (2 oz) or larger. 


Nadine responds best when soil temperatures are at or above 7°C (45°F). Seed piece depth should be 5-8 cm (2-3") under most conditions in well drained soils.  Plant spacing of 25 cm (10") for cut seed and approximately 28 cm (11") for whole seed.


Nadine requires a regular nitrogen fertilization.  A knowledge of field nitrogen will be helpful in determining levels of nitrogen to apply. Base Phosphorous and Potassium application levels on soil analysis data.  Herbicides containing metribuzin can be used; always follow label recommendations for soil type and conditions. Nadine gives good results on well drained soils. It will emerge quickly and develop a good ground covering foliage.


Harvest and Storage:
The variety has a determinate growth habit and has not demonstrated problems with vine destruction when grown with appropriate Nitrogen applications.  Nadine is not susceptible to internal bruising or to mechanical damage. It will store if properly handled, cured and ventilated. Apply a treatment of the fungicide thiabendazole to control fusarium and silver scurf.  Avoid free moisture in storage and keep potatoes at a consistent temperature. Optimum storage and packing results can be realized over an extended table potato shipping season.
