Consumers prefer high dry matter varieties with red skin. Rooster is the most popular variety in Ireland today.
Since its release in 1991, the area under production has grown to over 40% of the total potato ware area in Ireland today. The success of Rooster is due largely to its excellent taste and cooking quality, as well as its superior agronomic characteristics.
There are a number of important factors to consider when selecting a potato variety for the ware trade.
- Eating quality
- Keeping quality
- Disease resistance
- Seed availability
Yield – High yields are essential to enable producers to make a profit. Variety is a major determinant of yield.
Eating quality – Although quality preferences of consumers are changing most consumers prefer high dry matter potatoes and red skinned varieties.
Maturity – Choose varieties which mature in succession – aim to have harvesting completed by the end of October.
Keeping Quality – Varieties differ in their suitability for prolonged storage. Varieties like Golden Wonder and Rooster store well. Kerr’s Pink is difficult to store.
Disease Resistance – Varieties differ in their resistance to disease. Losses can be reduced or eliminated by being familiar with the disease resistance of the varieties being grown so that adequate control measures can be taken.
