General remarks
Camel is a mid early variety for with cooking type AB for the fresh market. The tubers are oval shaped with dark yellow flesh and a dark red skin. The cooking type is AB with a dry matter content of 18.3%. The variety is cultivated in North Africa and Europe.
Maturity
Medium early.
Seed treatment
Camel has a strong top sprout dominance and is rather sensitive for sprout damage. It is advised to order the seed potatoes timely and plant after a pre germination of several weeks to brake the dormancy.
Cultivation
This variety is rather sensitive to spraing and average for common scab and it is advised not to plant in to light soils, with seed that is out of dormancy. The foliage development is quick, but not to abundant. Camel is not sensitive to a Metribuzin treatment.

5. Camel Fertilisation Harvest Storage Resistance to diseases
Camel requires a slightly moderate N-fertilisation of 200 kg / ha, well adapted to the soil analysis. A split application of 2/3 at planting and 1/3 after tuber set is recommended. For Phosphate and Potasium the normal advice application is recommended.
Harvest
The variety Camel needs sufficient time after haulm killing for the mother tubers and the skin development. (Some 3-4 weeks) Harvest with care, to avoid excessive bruising.
Storage
Camel has a good dormancy. Advised is to start with skin healing and drying directly at harvest. After wound healing it is advised to avoid moisture in the storage, to prevent the development of silver scurf.
Resistance to diseases
Camel has a broad nematodes resistance, to Potato Cyst nematodes Ro1-4 and Pa 2 and 3. Normally treatments against late blight are recommended. Average against common scab.

El Mundo is little sensitive to Little Potato Disorder. The variety is sensitive to Rhizoctonia solani; tuber treatment before planting is recommended.

8. El mundo Cultivation Fertilisation Harvest Storage
Plant the seed tubers at soil surface level (normal depth). El Mundo has a normal emergence and first development. This variety gives a high and strong canopy with thick stems and exuberant flowering. El Mundo is very sensitive to Sencor (Metribuzin). Sencor can cause damage to the foliage. This herbicide should only be applied before harvest. Mechanical weed control or an alternative herbicide like Basagran (Bentazon) is preferred.
Fertilisation
A moderate Nitrogen fertilization is recommended to avoid a too strong canopy development. Specific for the desert areas, a total amount of Nitrogen between 200 and 240 kg/ha is recommended for El Mundo. At the start of the crop, El Mundo needs 250 kg Potassium. A small second application of Potassium as a top dressing is advised.
Harvest
For El Mundo, it is important to have a mature crop at the date of haulm killing. It takes time for El Mundo to have a fixed skin. Little susceptible to bruising.
Storage
El Mundo has an average dormancy. Little susceptible to Silver Scab.

13. Safari Growing instructions (table potatoes) General remarks Maturity
Safari is a variety for the fresh market with big tubers and a very high yield. Also suitable for the use as "Baker". The best results are coming from the countries around the Mediterranean Sea, but will also have a future in Cuba and the United Kingdom. The shape of the tubers is oval to round oval. The colour of the skin is during growing season somewhat brown. When Safari is mature, this will disappear, resulting in a nice yellow skin colour. The dry matter content is average to low (19,1%). The cooking type of Safari is B with no discoloration after cooking. The taste of Safari is excellent.
Maturity
Late.
Seed treatment
Safari has a slow and irregular emergence. It is advisable to use pre-sprouted seeds.
Cultivation
This variety is somewhat sensitive to common scab. Therefore it is important to avoid dry soils with a high organic matter. It is also advisable to keep the ridges moist for a few weeks during tuberisation. Safari has a rather small leaf development and the crop will be somewhat open during growing season. Safari is a little bit sensitive to Sencor. When using this herbicide, a slight yellowing of the leaf may occur.

14. Safari
Fertilisation
Safari does not require a lot of N. fertiliser. A split application is recommended.
Harvest
The large tubers of Safari are rather sensitive to internal bruising. It is recommended to harvest with care.
Storage
Safari has a long dormancy period en can be well stored for a long period.
Resistance to diseases
Safari is resistant to Potato Cyst Nematodes (Ro1, 4) and to wart disease, race 1. Moderately susceptible to leaf blight and hardly susceptible to tuber blight. It seems to be that Safari is somewhat sensitive for PVY.

15. Salinero Characteristics Fresh market Maturity: medium late
Fairly high yield
Oval – round oval tubers
Deep yellow colour of skin and flesh
Dry matter content: 21.2%
Cooking type B, practically no discoloration after cooking
Resistant to potato cyst nematodes, Ro1,4
Strong against common scab 

16. Salinero Growing instructions (table potatoes) General remarks
This variety will find its way as a potato for the fresh market in the luxury segment in Europe. The yield is rather high. The big, oval/round oval shaped tubers have a dark yellow colour. Also the colour of the flesh is dark yellow. Because the skin is mostly smooth, the Salinero is also suitable for washing and packing. The dry matter content is with 21,2% rather high. The cooking type is B with hardly any discoloration after cooking.
Maturity
Medium late.
Seed treatment
The number of tubers per plant of Salinero is rather good. A normal pre- sprouting is mostly sufficient to obtain a good number of stems per plant.
Cultivation
Because Salinero is rather strong against common scab and spraing, this variety can also be grown on lighter soils. There are no special recommendations regarding planting distance and depth. Slightly sensitive to Metribuzin treatments.

17. Salinero Fertilisation Harvest Storage Resistance to diseases
For the time being an average N- and P-fertilisation seems to be sufficient. Because of the average sensitivity to black spot, a good Potassium (K)-fertilisation is recommended. To stimulate the foliage development it is recommended to give the N-fertilisation before planting.
Harvest
This variety has an average tolerance to internal bruising. It is advisable to take care at harvest and avoid to high drops.
Storage
The dormancy of Salinero is rather good and therefor this variety can be stored for a longer period.
Resistance to diseases
Salinero is resistant to Potato Cyst Nematodes Ro1-Ro4 and resistant to wart disease (race 1). Somewhat sensitive to foliage blight, but very little susceptible to tuber blight. Not sensitive to spraing. Rather high resistance to common scab and gives no YNTN tuber symptoms.

18. Tyson Characteristics Fresh market – baker Maturity: medium late
High yield
Round oval tubers
Light yellow colour of skin and flesh
Dry matter content: 20,9%

19. Tyson Growing instructions (table potatoes) General remarks Maturity
Tyson is a main crop, early bulking table potato for the retail fresh markets in Europe and South West Asia. With a bright, yellow skin and light yellow flesh, the market for the Tyson will concentrate on traditional markets and pre packers. The cooking type is AB (rather firm cooking) with no discoloration after cooking. The tubers of this variety are round oval and have a uniform shape and good skin finish. The dry matter content is good (20,9%) and this variety can be used in the baker market. The dormancy period is rather short.
Maturity
Medium maturing, with an early tuberisation.
Seed treatment
A short heat treatment before planting to break the apical dominance is mostly sufficient to achieve a well developed crop. Planting directly from storage gives a later crop with more tubers.
Cultivation
Tyson is very strong against scab, but susceptible to spraing and can be planted on most types of soil. After complete foliage development, the ground cover is sufficient and the foliage is fairly tolerant to warm weather conditions. Although the tuber resistance is quite good, normal treatments against late blight are recommended. Tolerant to Metrobuzin applications.

20. Tyson Fertilisation Harvest Storage Resistance to diseases
The advise for the moment is to supply a normal N fertilisation. If the application of N will be split, the second application should be around the time of tuberisation. For Phosphate and Potassium also the normal applications are recommended.
Harvest
Tyson has a good skin finish and is not sensitive to internal bruising. However, caution at harvest is always recommended because of the demands for the high quality market.
Storage
Because of the rather short dormancy period, for medium to long storage it is recommended to use cold stores.
Resistance to diseases
Resistant to Potato Cyst Nematode Ro1, 4, and fairly resistant Pa2 and immune to wart disease fysio 1. Normal susceptible to foliage blight (Phytophthora infestans) and fairly strong for tuber blight. Strong against common scab.
