Disease resistances interesting for rootstock

[nicollas]

Hi,

in an attempt to find OP or at least "classical" F1 suitable to be rootstock instead of the pricey rootstock F1 seeds, i've imported the table of resistances found here to a database and made a query to see what cultivars have the most resistance to diseases related to rootstock. Here is the table result, the # columns is the sum up of resistances for the considered diseases. Well i've found no OP with at least 4 resistances.

I'm interested by any return on OP as rootstock, not necessarily on diseases resistance, i would be interested by cultivar/accessions that are vigorous or with great root system, and that can ripens fruits where tomatoes can (it seems that some wild accessions could do the trick but that reproducing seeds is difficult to achieve in temperate zones).

Valley Cat is supposed to have resistance to three races of nematodes.

I'm surprised that list doesn't include Big Beef which is one of the more widely available and cheap F1s that has very good disease resistance. However it doesn't have resistance to all types of fusarium which should not be a problem unless you are very far into the Deep South or Central America. I have a fair amount of experience with different rootstock that I have experimented with and found Big Beef to be one of the best if not the best of the seeds available at a cheap price. For a top notch rootstock which is a pure rootstock that has had very impressive results for me is one called RST-04-106-T. It is resistant to almost everything that is soil born and it the resulting graft generally produces more than the others I have tried. I have also had good results with Multifort, Estamino, and Maxifort.
