Resistance vs tolerance, lets put some definition to it
I snipped this from another website so we can engage in a conversation about the difference. In context, it is about a parasitic mite. I think we can extend the definition to embrace fungal and bacterial diseases.

I grew Plum Regal this year which is claimed to have "intermediate resistance to early blight." Based on my single observation this year (and previous as well), I would say this claim is accurate. While all other varieties in the garden were going down from early blight & septoria, this one kept growing/producing strong. However, once blight and septoria did show up on Plum Regal, it went down hard and fast. This seems like a possible case of resistance to early blight but little tolerance of it according to the above definitions. Thoughts? Lee

Darrel,as you probably know I've been harping on the difference between resistance and tolerance for many years here at Tvill and elsewhere.
I was first alerted to it when some commercial growers bought tomato seeds and they were advertised as having resistance to this and that disease,and they weren't. They sued the companies for misrepresentation and won, and after that the Association of Tomato growers,or whatever they are called,said that commercial breeders should use tolerance and not resistance. Resistance implies total resistance,no such thing IMO. Just too many darn variables that can and do affect the possiblle presence of tomato diseases. Carolyn
