Quantitative resistance is, by definition, partial

Slide 12

Lots of examples of this type of thing

“Ghost” effects

CAVEAT

So are Quantitative resistance genes similar to major R-genes?

Perhaps R-genes that interact weakly with their corresponding Avr genes cause partial resistance?

Questions

Slide 21

R-genes can’t be the whole story surely!

Slide 23

Slide 24

Is quantitative resistance effective against multiple diseases

Slide 26

So what use are dQTL?

The Catch-22 can be avoided if:
