_"Hi Paul,
\
the Tea genes seemed to wash out any color the cross should have shown.
Can you elaborate on this? "_
I can. These comments are based purely on observations regarding Miniature X Tea crosses made over the past decade.
With the exception of ‘Avandel’ I have used Miniature breeders with a reputation for breeding good color in their offspring. (Ironically ‘Avandel’ was the one Miniature that did eventually give me a reasonably well colored seedling: ‘Won Fang Yon’) I used both ‘Joycie’ and ‘Golden Angel’ extensively, ‘June Laver’ to a lesser degree, and 1-72-1, the Moore yellow breeder. When paired with pollen from ‘Safrano’, ‘Lady Hillingdon’, ‘Bon Silene’, ‘Mons. Tillier’ (almost certainly ‘Archiduc Charles’ in the USA), and ‘Gloire de Dijon’ these crosses produced, with very few exceptions, white, creams and pale pastel colors of little merit. Most had severe Mildew problems and so were weeded out pretty early in the process.
If I paired the same Miniature parents with well pigmented modern shrubs of various types, and even sometimes with pink or white Hybrid Musks, I got much better coloring than the Tea crosses.
As I mentioned ‘Won Fang Yon’ was one of the very few that were kept, and it has a deep coral color that darkens to a red-coral as it ages. Also kept was a seedling from ‘Joycie’ X ‘Mons Tillier’ which was a very nice peachy-pinkish-orangey combo that also darkened with age to show more and more red on the upper petals. This seedling was set out in the test garden for evaluation where it has not exceeded 14" in height. It was taken off the list because of poor vigor. Two years later I budded it to R. multiflora and it gained a wee bit of vigor, but not nearly good enough for commerce. Oh, and I once had a dark red seedling years ago from ‘Rise ‘N’ Shine’ X ‘Francis Dubreuil’, but the plant we grow in the US as ‘Francis Dubreuil’ is almost certainly the HT ‘Barcelona’.
There is one Miniature-Tea plant that I work with most years, and its a Ralph Moore rose called ‘Its Showtime’. Ralph sold this variety off to a SoCal nursery years ago and it was marketed as a Hybrid Tea. It came from ‘Joycie’ X ‘Bon Silene’ and is in many ways intermediate between the two. Its a bit of an awkward grower, I find, and could stand to have more, denser foliage, but I have found it has serious merit as a breeder. It often passes on excellent vigor, good coloring in the peach/yellow/orange range, and large, full OGR bloom form. Fragrance is often present in its offspring as well. If there was one Miniature/Tea hybrid I would recommend for breeding, that is absolutely the one to get, IMO. It only works well as a pollen parent, though. It may set seed but these rarely germinate, even if they do go full term.
So, thats my take on it. I have no plans to reopen the Miniature X Tea breeding efforts, but prefer instead to work with ‘Its Showtime’ which has shown itself to be a good next step in breeding. If I were interested in breeding Mini Teas, I might go back and retry some of these crosses using other Teas and maybe other Minis as parents, but thats not my goal: I am working towards breeding full-sized shrubs and some climbers. Since I quit doing the Tea/Mini crosses I have acquired ‘E. Veyrat Hermanos’, which I might introduce into my work if I can find a worthy seed bearer. But I am hesitant for many reasons, not the least of which is ‘E. Veyrat Hermanos’ sparse rebloom.
Oh, one last note: in 2006 I made a cross of my old favorite ‘Joycie’ and ‘Fortune’s Yellow’, just to see if ‘Fortune’s Yellow’ was actually capable of breeding remontants. (Breeding records suggest that it parented some repeaters on occasion) In 2007 I germinated about 35 plants, and I kept about 30 of the most vigorous ones and they went into gallon cans. In Spring 2008 three of these bloomed for the first time. One was a fiery orange single with a deep brownish red eye, and one was a 1.5" double pink bloom which, while pretty, wasn’t remarkable. The third seedling was a surprise: 4" very double blooms that opened slowly to reveal a rumpled center. It started out a smoky dark pink and aged to a very odd slatey purple/lavender! This was put in a much larger pot and grown on where it eventually made several half in thick canes 7 feet long. I’m going to post photos of this next Spring when it blooms again. Who knows…maybe it will gain some remontancy with age.

Paul
