From about 100 pollinations onto 6 different seed parents, 820 seeds were collected and planted this past January. Presumably due to an incompatibility of the species with my seed parents, germination was significantly reduced as seen below. On the right side of the seedling bench the same seed parent was planted in groups where various pollens were used. The "Rosa arvensis" seedlings are in the space with the fewest germinations.
After the seedlings started to grow, it was apparent that most of the seedlings would be nonremontant and would not bloom for another 1 or more years.
Sprinkled here and there however, were a few seedlings that were forming flower buds. The orange and pink seedlings seen in the above photo are not seedlings of "Rosa arvensis", but are from nearby other crosses. The first "Rosa arvensis" seedling to bloom is shown below.
As the nonremontant seedlings continued to grow, it was very apparent that they would soon overgrow and smother the few seedlings that were blooming, so these were removed and planted into pots. They will be evaluated next spring and the best of these will be kept for future breeding.
Below are photos of blooms of four other repeat blooming seedlings of "Rosa arvensis". Knowing that the seed parents were orange and dark red, it is clear that the creamy white color coming from "Rosa arvensis" is a strong trait.
I was very glad to find that a remontant gene could be recovered from the "Rosa arvensis" pollen parent. There are some early signs that a couple of these will be floriferous. I will post photos of them next spring.
