Great to see this, thank you for sharing!
Curious to learn more about the Chinese hybridizer he mentioned, but I canāt figure out how to transcribe the name which makes searching difficult. The first variety mentioned in the video bred by Yang Yue Ji (sorry thatās probably wrong?) is called Nirvana, but HMF search leads to two roses that are definitely not that one.
Based on the meilland facebook post from earlier in the year

I think its ęØåÆę which translates to Yang Qikunā¦but even with that google didnāt help.
Found him!
Itās Yang Yuyong, founder of YYY Roses (now renamed Kunming Yang Chinese Rose Gardening Co.)

Short blog about a visit to his gardens and a couple pics of roses he bred:

An article that mentions him regarding IP protection laws for breeders in China and mentions the collaboration with Meilland :

Unfortunately I canāt find much more about about the roses he has bred. He is unknown to HMF.
Hi,
Yes NIRVANAĀ® is one of our registered trademark and we use it for different varieties at different time of our history 
Yang Yuedji is the breeder of the variety named Hujingshi which we are caring for outside of China As it is a Cut flower, usually you donāt get much info on HMF as most of the varieties are not known to the āgarden worldā
Yang Qikung is our representative in China for cut flower development since 1999. He is not the breeder of Hujingshi NIRVANAĀ®
As said in my previous post, the cut flower word is not known by the garden world (unless few examples that was released before 2000)
YYY breeding is mostly for cut flowers and hydrangeas today. The 1st varieties that we trialed was sent in 2006. Some have been protected in China but only NIRVANAĀ® Hujingshi is commercial outside of China.
Thank you for the information @MatthiasMeilland !
Even if we canāt grow them itās always interesting to learn about new cut flower roses being created, and I am glad that fragrance is a part of the current focus!
Thanks David,
Happy that you enjoyed it
Iām surprised they let @MatthiasMeilland in the greenhouses. Jk 
I have the key
