1- Portainjertos 161-49 Couderc

The 161 49 C rootstock is very widespread in Spain due to its optimal adaptation to limestone soils. It is currently being displaced by RU-140.

2- Breeder

Rootstock obtained by Georges Couderec , to which his name refers.

3- Genetic Origin

It comes from the cross of Vitis Riparia and Vitis Berlandieri.

4- Agronomic Characteristics

  • Resistant up to 25% active limestone .
  • It is of medium vigor and provides the graft with a regular production and a slight advance in the ripening dates.
  • Drought resistance is medium to good.
  • It is slightly sensitive to temporary excesses of humidity in spring.
  • It is well adapted to soils calcareous or clayey-calcareous, very compact, light and deep.
  • Avoid on very compact soils.
  • Its resistance to salinity is zero.

5- Resistance to nematodes

Resistencia media a Meloidogyne incognita, y sensible a Meloidogyne arenaria.

6- Adaptation to the environment

The speed of development and entry into production provided by the 161-49 is a bit slow.

The vigor provided by the rootstock is medium and the vegetative development is balanced.

7- Interaction with the variety

The products obtained from plants grafted on 161-49 are normally of high quality and the grafts made with Chardonnay , Colombard, Pinot Noir and Ugni Blanc are particularly appreciated.

It gives problems of incompatibility with the graft on varieties such as Carignan, Gammay and Servant.
