Thanks for the new rootstock forums, these will be really helpful.
C35 is really popular in our city for the last 6-7 years.Many nurseries started to grow C35 instead of sour orange.
No scientific results but we have our own experience.We have
Dobashi Beni Satsuma Mandarins both on C35 rootstock and sour orange.
After 4 years it is really obvious that C35 rootstocks develop much bigger and hardy fruits.
Best,
