Results from the L83 crosses: 77-07

At left: 77-07 selections. Click on the photo to see a full sized image.

In 2007 I made a few crosses using the Agriculture Canada breeder L83 by Dr. Felicitas Svejda. It is basically a R. wichurana and R. rugosa selection, multiple generations long. It also happens to be a tetraploid, making it particularly useful in breeding with modern lines. There were three crosses I got large numbers of seedlings from and L83 was the pollen parent in every case. 'Seed parents were: 'Golden Angel', 1-72-1 (Sister seedling to 'Rise 'N' Shine') and a proprietary red Floribunda I use extensively in breeding. Out of at least 70 seedlings of each cross, at least 40 of the two yellow groups were saved and potted into gallons and about 60 seedlings from the red cross were potted on.

77-07, the red group, has been the most fruitful. I would estimate that about 35% of these, a much higher number than expected, have been strong reds and several have been large blooms and very double. In the photo, 77-07-08 shows what some of the more double ones have looked like. Several of these have had fragrance and there was one that was a purple very similar to 'Tuscany'. So far about 20 of the reds have been moved on into 5 gallon containers and will be moved outside to watch their progress. This has been a very exciting group of seedlings and I am eager to continue trying new ideas with L83.

Last Fall, some members of the Rose Hybridizers Association received some of my surplus seedlings from the 77-07 group, so this information will be of particular interest to you. Have any of you seen any of the seedlings flower yet?
