Root stock for tomato
Tomato is a seasonal vegetable crop. It is one of the major vegetable crop in India and also in the world. India is the second biggest country in the world after China in terms of area an production.
This production is greatly affected and yield is reduced by the wilt which is one of the major disease of brinjal. Yield loss due to wilt may range from 11.67 to 96.67% (Ref01).
Vegetable grafting is a method to reduce the incidence of different species of wilt in tomato. For this we need a resistant rootstock for tomato grafting.
What are the different rootstock for tomato grafting?
The different rootstock for tomato grafting are as follows:
- Cherry tomato
- Cultivated brinjal
- Wild brinjal (Solanum torvum)
- Black nightshade (Solanum nigrum)
Cherry tomato is a wild species of tomato. It is a seasonal climber. Being wild in nature this species of tomato is more vigorous and resistant against many biotic and abiotic stresses.
- Very compatible with any variety of tomato.
- There is no compatibility issue.
- Cultivated brinjal is Solanum melongena.
- It is an indigenous varitey of F1 hybrid.
- Local varieties are perennial while F1 are generally seasonal or annual.
- It is compatible with tomato.

- Turkey berry is not very much compatible for tomato grafting.
Black nightshade (Solanum nigrum)
This is an annual shrub.
Black nightshade is compatible with tomato for grafting.
Which is the best rootstock for tomato grafting?
- Considering vegetative growth the best rootstock for tomato is cultivated brinjal or Solanum melongena.
- Considering flowering, fruiting and overall yield the best rootstock for tomato is cultivated brinjal or Solanum melongena.
- Considering soil-borne diseases the best rootstock for tomato is wild brinjal.
