Blight resitant tomatoes

 

Question for 'you guys':

Back in the old days I used to graft a Moneymaker to a desease resistant
root stock....with the current  selection of desease resistant varieties
there of course is little need for that today....but....

Any thoughts re doing the same thing today but grafting to a blight
resistant tomato?...H

 

"carried through" substituted for "affects"




Which part of the blight resistant tomato?

Resistance to blight is genetic and is carried through the
entire plant.

Blight attacks the leave of plants.

However when grafting plants, no genes are transferred.

Basically all thats being done when grafting is joining up two
bundles of pipes or veins inside the stem. Veins from the roots
(or from the main stem in addition) with one set of genes, to veins
leading to the leaves with possibly an entirely different set of
genes.

So if you grafted ordinary tomatos onto the rootstock of blight
resistant tomatoes you could still get blight.
