Although the P-1147 is a rootstock that is used practically nothing in today’s viticulture, we describe its most important characteristics.
1- Usual name of the rootstock
3- Year of obtaining
4- Genetic origin
This comes from the cross between the grape species of Vitis berlandieri and Vitis rupestris cv. Martin.
5- Resistance to soil parasites
The 1447 P offers a high degree of tolerance to the phylloxera , the radical enemy of the vine.
The same occurs with the nematodes Meloidogyne incognita and Meloidogyne arenaria, whose resistance to these is very good.
6- Adaptation to the environment
The 1447 P rootstock is characterized by a medium to good adaptation to calcareous-type soils.
It is resistant up to 17% of active limestone and to drought.
7- Interaction with the variety and production objectives
The vigor transmitted by the 1447 P rootstock is important, which allows obtaining very good yields.
The speed of rootstock development is a bit slow, compared to other rootstocks in the world of viticulture.
This rootstock pattern does not have clones in viticulture.
