Thank you for posting this! And, I'd like to thank all of the growers & scientists who have brought us this hope too.

You may also thank Jeekin at the post at the RHA if you're inclined. https://rosebreeders.org/forum/viewtopic.php?f=2&t=56908 

Jeekin posted this to the RHA thread. Perhaps it may help? "I work in the rose breeding lab here at TAMU and we are studying the RRD/RRV resistance. As you can read in these two recently published papers, our lab needed roughly 3 years of in field phenotyping to determine which individuals in the populations were resistant or susceptible. This patent you found was from a colaborator lab at TAMU that is focused on finding a more time efficient and labor efficient way we can screen materials in our breeding program for viral resistance. The goal is to create infectious clones that will allow us to innoculate a greenhouse full of seedlings and then PCR test the plants for presence of the virus a couple months later in stead of 3 year field trials. Greenhouse screening greatly reduces the cost of our studies as a lot of money is spent field trials for the maintenance of plants. In short they are patenting a way to potentially quickly screening progeny for resistance.

Our two papers are below and open access.

Let me know if yall have any questions about this,

Jeekin"

Glad there's some progress, but most likely we're still many years (possibly decades) away from roses bred for RRD resistance. If it ever happens.

...and then to transfer that resistance to all the roses we currently love.😣
