Crimson Crush F1 is a new outdoor variety this year, reported to be the 'most' blight resistant available, carrying both the PH2 and PH3 genes. I didn't have a lot of information but a thread on A4A puts it all together better than I can. (Information was supplied with trial plants in a giveaway).
The story of Crimson Crush
Resistance genes were discovered in wild species of tomatoes.
These were transferred into our cultivated tomato species through conventional breeding methods.
One parent line was developed from a cross in the UK in 2005 with further selection taking place in outdoor trials in Worcestershire & Warwickshire.
This parent contains the PH2 gene.
The second parent was selected in the USA
This parent was shown to have excellent blight resistance even in very warm, humid conditions.
This parent contains the PH3 gene.
The offspring of these parents resulted in vigorous plants with very good temperature tolerance and exceptional blight resistance thanks to having both the PH2 and PH3 genes.
The earliness and excellent eatii qualities were discovered in trials and blind taste tests over a two year period in various trial locations throughout the UK.
Crimson Crush is the result and is now available to you!
This was an added paragraph to show the results of scientific tests:
Whilst Crimson Crush is fully resistant to Blight, in trials at Bangor University, where a solution of blight spores was applied directly to the plants, some spot infection occurred, this infection affected less than 10% of the plant and the growth and productivity was unaffected, whereas control varieties were 100% infected and died as a result of the infection.
I can not make head or tail of the conclusion I think they might mean other varieties that were subjected to the same tests.
This is another claim that Dobies/Sutton make on the same leaflet:
After first selecting Crimson Crush for its super Blight Busting powers, we reselected it again by accident in a blind taste test, where it surpassed established names like Brandywine, Black Russian and a whole host of others.
