Now a days, to alleviate the problem of bacterial wilt in tomato, wild brinjal (Solanum torvum) is used as stock and grafting is emerged as very popular technique specially in gangetic alluvial zone where the problem of the BW is very severe. But, some farmers reported that the fruit of tomato which is produced from the grafted plant, contains some unpleasant smell of wild brinjal..Is there any report of such problem? Can you please illuminate me? Or its just a misconjecture of farmers?
@ Subhrajyoti Chatterjee,
Grafting in Tomato and brinjal is an old practice. Around 20 years back there was a report in the newspaper that one gardener has practiced such grafting. It is easily possible may be because both are from Solanaceae family and have 2n=2x=24 chromosomes. Since the wild member has been used as 'stock', for grafting. One has to study the chemical composition of wild member, to rule out the possibility on any unpleasant smell.

Exactly sir...There is no problem of graft incompatibility. Plant is also showing significant resistance against BW as well. But some farmers are reporting the unpleasant smell of grafted tomato. That's why i raised the discussion for my clarification. Thank you sir for your valuable comment.
I agree with M. C. Shidhu, it is very old technique, therefore currently give more emphasis to use the F1 of S. habrochaites X S. lycopersicom as root stock and the cultivated susceptible one as scion. This techniques become very popular and functioning well in different targets of new tomato root stock breeding, For details you can go through the Sakata booklet as:
