1- Vineyard patterns: Fercal

2- Usual name


3- Breeder

INRA (National Institute of Agronomic Research. France)

4- Year of obtaining


5- Genetic origin

Crossing of Berlandieri Colombard nº 1 B and 31 Richter

6- Resistance to soil parasites

The degree of tolerance of Fercal to root phylloxera is very high.

It also has a very high degree of tolerance to the nematodes Meloidgyne arenaria and Meloidogyne incognita, but its resistance to Meloidogyne hapla is medium.

7- Adaptation to the agricultural environment

  • The main characteristic of Fercal is its high resistance to chlorosis and its adaptation to calcareous soils.
  • Resists up to 60% total limestone , 40% active lime and a CPI of 120.
  • This rootstock tolerates damp conditions quite well in spring and its resistance to drought is medium to the extent that its root system has deeply installed roots.
  • It has difficulties to absorb Magnesium from the soil, accusing it when the potassium fertilization is excessive.
  • Vine varieties grafted with this rootstock may show magnesium deficiency symptoms .

8- Interaction with the variety of vine and production objectives

  • The Fercal has a good affinity with most of the grape varieties.
  • The vigor that this rootstock transfers to the vine varieties is medium high and is evident with its initial development speed and its early entry into production.
  • Its influence on the vegetative cycle of the vine is within the average.
  • In terms of fertility and yield , the Fercal is well balanced and allows to obtain quality productions.
  • It gives a particularly good result with the Syrah variety .
