Title: Bangor University research on late blight
Post by: Diane Whitehead on 2019-01-15, 03:12:02 PM
Tom Wagner reported that one of his tomatoes was part of a study for a PhD in Wales.  The doctorate was awarded to James Stroud in 2015.  I was hoping for a quick way to see the results of his trials, but haven't succeeded yet.

Before he began, in 2011, there was a suspicion that some strains of blight favoured tomatoes over potatoes.  Here are the objectives of the study:

Experimental Aims

Evaluate a wide range of existing tomato genotypes for resistance to late blight, caused by Phytophthora infestans.
Create an experimental mapping population of hybrid tomato plants that segregate for different blight resistance genes for understanding inheritance of resistance and selecting better varieties.
Establish whether the tomato based P. infestans population is different from the potato based P. infestans population and investigate which factors lead to host specialisation.

The thesis has been published, and I have read the abstract.;jsessionid=711592F7854B0F4352955A905943F197?

The conclusion of it:

Taken as a whole, the findings of these studies indicated that novel tomato cultivars with P. infestans resistance from a broad range of genes are needed to combat the threat from a highly diverse and evolving P. infestans population. The breeding and mapping work undertaken in this project makes some contribution to addressing this challenge, although further work is needed to fully capitalise on this.

So, no quick look at the list of tomatoes tested, though maybe if someone is able to download the whole thesis they could find the list.
