2004 and 2005 Seedling Report
The number of plants that had grown over 3 feet are in black, the number between 2 and 3 feet are in blue, the number between 1 and 2 feet tall are in red, below 1 foot are in green..
I used 4 grading terms: very good - over 3 feet; good - 2 to 3 feet; OK - 1 to 2 feet; and small - less than 1 foot. The very good and good should have the best chance of surviving the winter without having their roots "frost heaved" out of the soil. Many of the "OK" plants are from this spring's germination. The grading has nothing to do with any of the flowering characteristics.
===========================================
(acicularis-tetraploid ? X OP) X R-15 4, 2, 0, 0 plants
This is a "breeding material only" type cross. Both parents are single, spring blooming only. Both are hardy and disease resistant in northern Ohio. R-15 has good pollen, but when used as a mother, her seeds do not germinate readily (if at all).
(acicularis-tetraploid) is a selected plant from a number of seedlings obtained from open pollinated seeds of acicularis nipponensis. Acicularis nipponensis is normally a diploid. This selected plant has a larger flower and larger leaves so it is either a cross or a tetraploid.
R-15 is Golden Showers x Hazeldean. It was hybridized by Peter Harris. It is a tetraploid.
(acicularis-tetraploid ? X OP) X (Hansa X OP) 9, 1, 0, 0 plants
I suspect that Hansa produces some tetraploid pollen.
----------------------------------------------------------------
Autumn Sunset X OP 1, 0, 0, 0 plants From seeds provided by John Finnegan.
I am trying to find additional "yellow blood" to mix with my (Rugelda X R-15) plants, see http://home.neo.rr.com/kuska/RugeldaXR-15%20seedling.htm .
------------------------------------------------------------------
(Bonavista X OP) X (William Baffin X OP) 0, 1, 1, 1 plants.
Bonavista is Schneezwerg (a hybrid rugosa) X Nemesis (a diploid chinesis).
This cross should result in the formation of sterile triploids. Bonavista could help with flower form and repeat flowering. William Baffin could contribute greater winter hardiness.
(Bonavista X OP) X OP 0, 0, 1, 0 plants.
------------------------------------------------------------------
(Calocarpa X Nutkana) X (Agnes pollen plus (acicularis-tetraploid ? X OP) pollen) 6, 4, 0, 0 plants.
(Calocarpa X Nutkana) seeds were provided by Randy Hudges. It is a tetraploid.
I mixed the two pollens because I felt that the 2 offspring should be different enough so that I should be able to tell which was the father for each plant.
(Calocarpa X Nutkana) X (acicularis-tetraploid ? X OP) 5, 1, 0, 0 plants.
---------------------------------------------------------------------
Carefree Beauty X (Folksinger X Illusion) 1, 0, 1, 1 plants.
This cross is mixing some Kordes "blood" with two doses of Buck rose "blood".
(Carefree Beauty X Heritage) X Always Love You 0, 0, 0, 1 plants.
---------------------------------------------------------------------
Carefree Sunshine X OP 0, 0, 2, 1 plants. From seeds provided by Joan Monteith.
One of these has produced a nice yellow flower while still a very small plant.
----------------------------------------------------------------
(Corylus X OP) X (acicularis-tetraploid ? X OP) 4, 0, 0, 0 plants.
Corylus is R. nitida X R. rugosa ruba. It should be a diploid. This is just a "breeding material only" type cross. Both parents, Corylus and acicularis, are single, once blooming. Both are hardy and disease resistant in northern Ohio. The cross should be a triploid but perhaps some of the pollen will be tetraploid.
(Corylus X OP) X mixed pollen 1, 0, 0, 0 plants.
A comment about "mixed pollen". After I use a pollen individually for about a week, I combine it with other old pollen for "mixed pollen" experiments.
--------------------------------------------------------------------
((Delicata X OP) X Will Alderman) X R-15 0, 2, 0, 0 plants.
I wonder if ((Delicata X OP) X Will Alderman) is a tetraploid (based on its behavior in earlier crosses)..
((Delicata X OP) X (( Therese Bugnet X OP) X OP) ) X (tetraploid acicularis(?) X OP) 10, 1, 0, 0 plants.
I also wonder if ((Delicata X OP) X (( Therese Bugnet X OP) X OP) ) is a tetraploid.
-------------------------------------------------------------------
(Dornrosen X Baby Love) X OP 0, 0, 1, 1 plants. From seeds provided by Joan Monteith.
--------------------------------------------------------------------
Dortman X Illusion 2, 1, 0, 0 plants.
These are both Kordes roses, probably nothing "earth shaking" will come from this type of cross. It is hard to see how Dortman "blood" could improve Illusion.
---------------------------------------------------------------------
(Flora McIvor X OP) X OP 0, 0, 0, 1 plants. From seeds provided by Dave Zlesak.
Dave Zlesak reports that this should be tetraploid.
-----------------------------------------------------------------------------------
Folksinger X (Prairie Youth X OP) 1, 0, 1, 2 plants.
Prairie Youth is an early Morden Exp. Farm (Canadian government) introduction, its background contains a number of hardy species.
Folksinger X William Baffin 0, 0, 1, 1 plants.
Folksinger X (William Baffin X OP) 2, 2, 0, 0 plants.
Folksinger X (Royal Edward X RSMK-1) 2, 1, 0, 1 plants.
RSMK-1 is a cross of R. rugosa alba X (J.W. Fargo X (Donald Prior X R. arkansana) X mixed arkansana hybrids). It is a tetraploid. The pollen was provided by Peter Harris.
Folksinger X (Morden Centennial X OP) 0, 0, 1, 0 plants.
Folksinger X (George Vancouver X John Davis) 0,1, 3, 2 plants.
The hope is that the above crosses of Canadian Government developed roses with Folksinger could result in a more winter hardy rose with a flower similar to Folksinger.
Folksinger X Illusion 1, 0, 1, 0 plants.
Folksinger X Dortman 1, 2, 1, 0 plants.
As the above 2 crosses indicate, I also like to cross Buck and Kordes lines to find new disease resistant, hardy roses.
(Folksinger X Illusion) X (William Baffin X OP) 0, 0, 1, 0 plants.
(Folksinger X Illusion) has been one of my most successful crosses so far, see: http://home.neo.rr.com/kuska/folksinger%20X%20Illusion.htm Hopefully, this cross will add more winter hardiness to an already reasonably winter hardy rose.
--------------------------------------------------------------------
(George Vancouver X John Davis) X (Basye's amphidiploid X OP) 5, 2, 2, 0 plants.
Bayse's Amphidiploid is (R. abyssinica X R. rugosa ruba). The seeds of ( Bayse's Amphidiploid X OP) were provided by Randy Hudges. It is a tetraploid. This is a "for future breeding type cross".
(George Vancouver X John Davis) X William Baffin 1, 1, 0, 0 plants.
(George Vancouver X John Davis) X Culbert Grant 1, 0, 0, 0 plants.
(George Vancouver X John Davis) X (Rugelda X R-15) 1, 1, 1, 0 plants.
(George Vancouver X John Davis) X ((Delicata X OP) X (( Therese Bugnet X OP) X OP) ) 5, 0, 0, 0 plants.
I expect that this cross will yield tetraploids.
(George Vancouver X John Davis) X OP 5, 2, 2, 0 plants.
(George Vancouver X John Davis) X ( Sir Thomas Lipton-tetraploid? X OP) 0, 1, 0, 0 plants.
Each of the above is an attempt to capitalize on the fine qualities of the mother. Unfortunately, I do not have the extensive facilities required to grow hundreds of each cross so these will probably end up as "of future breeding interest only" plants (unless I am very lucky).
-------------------------------------------------------------------
Golden Artic X OP 0, 0, 1, 0 plants. From seeds provided by John Finnegan.
-----------------------------------------------------------------
(Hansa X OP) X (acicularis-tetraploid ? X OP) 2, 0, 0, 0 plants.
These should be triploids. Hopefully, some of the pollen will be tetraploid..
--------------------------------------------------------------------
(Henry Hudson X OP) X (Pomifera X OP) 2, 0, 2, 0 plants.
Pomifera is a Caninae type tetraploid so the pollen should contain only 7 chromosomes. Thus, the offspring should be diploid and contain less rugosa character. This will probably give a rose for future breeding interest only.
(Henry Hudson X OP) X mixed pollen 3, 1, 2, 0 plants.
-------------------------------------------------------------------------
Heritage X mixed pollen 1, 0, 0, 0 plants.
From my previous hybridizing, I would expect Heritage to improve the flower of whatever it is crossed with.
-----------------------------------------------------------------------
Illusion X William Baffin 0, 0, 2, 0 plants.
Illusion X (William Baffin X OP) 0, 0, 0, 1 plants.
(Illusion X John Davis) X (George Vancouver X John Davis) 1, 0, 0, 0 plants.
I am surprised that this cross did not result in a large number of healthy seedlings.
(Illusion X John Davis) X William Baffin 1, 0, 3, 0 plants.
Hopefully, this cross will give a better flower on a William Baffin type plant. The above is a cross where hundreds of offspring would probably pay off with at least one of commercial quality.
(Illusion X John Davis) X (acicularis-tetraploid ? X OP) 1, 0, 0, 0 plants.
(Illusion X John Davis) X (Basye's amphidiploid X OP) 1, 1, 0, 0 plants.
The above two are probably mainly of future breeding interest.
-------------------------------------------------------------------
(Jens Munk or Therese Bauer) X Will Alderman 0, 1, 2, 1 plants.
In earlier crosses of this type, I got what I consider as "improved rugosas".
---------------------------------------------------------------
Leverkusen X (Rugelda X R-15) 0, 0, 0, 2 plants.
It was disappointing not to get better seedlings from this cross.
--------------------------------------------------------------
Litchkoninig Lucia X OP 0, 1, 2, 2 plants. From seeds provided by Joan Monteith.
----------------------------------------------------------------
(lost tag, blooms all summer, pink double, looks like explorer, rugosa cross) X OP 1, 7, 20, 14 plants.
(lost tag, blooms all summer, pink double, looks like explorer, rugosa cross) X mixed yellow pollen 0, 1, 2, 1 plants.
The mother is a "small tree" type rose that may be a successful commercial introduction. It is a shame that I lost the label. I still hope to find it if (and when) I dig the plant up to move it. The growth characteristics are similar to some of my older rugosa X Canadian type crosses. However, those are mainly spring bloomers and, so far, are female sterile.
----------------------------------------------------------------
(Martin Frobisher X OP) X (Pomifera X OP) 1, 0, 3, 0 plants.
(Martin Frobisher X OP) X (Basye's amphidiploid X OP) 0, 2, 0, 0 plants.
Depending on the chromosome count of the mother these could be diploid and triploid or triploid and tetraploid.
-----------------------------------------------------------------
(micrugosa X OP) X OP 0, 0, 0, 1 plants.
-----------------------------------------------------------------
(Morden Amorette X OP) X Will Alderman 1, 0, 0, 0 plants.
I suspect that Will Alderman produces some tetraploid pollen. We will have to wait and see if this is fertile.
----------------------------------------------------------------------
(Morden Centennial X OP) X (William Baffin X OP) 1, 1, 0, 0 plants.
The 2 Canadians were bred at different research stations with different goals.
---------------------------------------------------------------
non-rugosa seedling-unknown parents X (Bonavista X OP) 3, 1, 0, 0 plants.
The mother may have R. Canina type chromosome behavior; if so, the offspring may not be very interesting as the mother's characteristics may dominate.
-----------------------------------------------------------------------
Park Direktor Riggers X William Baffin 1, 0, 1, 0 plants.
Park Direktor Riggers X (William Baffin X OP) 0, 0, 3, 2 plants.
----------------------------------------------------------------------
((Nearly Wild X OP) X (( Therese Bugnet X OP) X OP)) X (Pomifera X OP) 7, 3, 2, 0 plants.
Who knows what these will look like. The genes seem to be able to get along.
--------------------------------------------------------------------
(Palustris-tetraploid) X OP 2, 3, 4, 4 plants. From seeds provided by Dave Zlesak.
((Palustris-tetraploid) X John Cabot) X OP 2, 5, 4, 2 plants. From seeds provided by Dave Zlesak.
I have not been successful using John Cabot as either a mother or as a pollen donator. Perhaps if John Cabot is crossed with this one, I will have better luck.
-----------------------------------------------------------------
(Pomifera X OP) X ((Martin Frobisher X OP) X (( Therese Bugnet X OP) X OP)) 0, 0, 1, 7 plants.
At first glance this cross may look impressive, but Pomifera is a Caninae type tetraploid so this one may not have much pollen parent "blood".
-----------------------------------------------------------------------
Prairie Harvest X William Baffin 2, 4, 2, 0 plants.
Prairie Harvest X ( mixed pollen of (Rugelda X R-15) and R-15) 1, 0, 0, 1 plants.
Hopefully, this will be a yellow. At the time of pollination I did not have a lot of either of these 2 pollens left so I pollinated with both.
--------------------------------------------------------------------------
Rambling Red X OP 2, 0, 3, 5 plants. From seeds provided by Steve Johnston.
Some of these have produced nice red flowers while still very tiny. What will Rambling Red crossed with Illusion look like?
--------------------------------------------------------------------
(Rugelda X OP) X Agnes 0, 1, 1, 5 plants.
Many of these germinated but most died. I am very interested in what the flower will look like.
------------------------------------------------------------------------
rugosa seedling-unknown parents X (Bonavista X OP) 1, 0, 0, 0 plants.
rugosa seedling-unknown parents X (( Therese Bugnet X OP) X OP) 1, 1, 0, 1 plants.
rugosa seedling-unknown parents X R-15 2, 0, 0, 0 plants.
Strange cross, I wonder if these were actually self pollinated. I do have one mature rugosa X R-15 plant where the bright red flower may indicate that R-15 was indeed the father.
rugosa seedling-unknown parents X mixed pollen 1, 0, 0, 0 plants.
------------------------------------------------------------------
( Sir Thomas Lipton-tetraploid? X OP) X Heritage 0, 0, 1, 2 plants.
( Sir Thomas Lipton-tetraploid? X OP) X open pollination 1, 0, 0, 0 plants.
(Sir Thomas Lipton-tetraploid? X OP) X Simon Fraser 2, 1, 0, 0 plants.
I am expecting that the Simon Fraser seedlings will be fertile. If so, this would indicate that my (Sir Thomas Lipton X OP) plant is indeed a tetraploid.
(Sir Thomas Lipton-tetraploid? X OP) X (( Therese Bugnet X OP) X OP) 1, 2, 0, 1 plants.
------------------------------------------------------------------
(Suzanne X OP) X (Bonavista X OP) 0, 0, 3, 6 plants.
(Suzanne X OP) X mixed rugosa pollen 1, 3, 8, 5 plants.
(Suzanne X OP) X (( Therese Bugnet X OP) X OP) 0, 1, 3, 4 plants.
Many of the above type germinations died.
-------------------------------------------------------------------------
((Therese Bauer X OP) X Hawkeye Belle) X (Carmenetta X OP) 1, 0, 0, 0 plants.
Carmenetta is R. rubrifolia X R. rugosa. It is a tetraploid.
((Therese Bauer X OP) X Hawkeye Belle) X ((Delicata X OP) X (( Therese Bugnet X OP) X OP)) 2, 2, 0, 0 plants.
I wonder whether (Delicata X OP) X (( Therese Bugnet X OP) X OP) is a tetraploid.
(Therese Bauer X OP) X mixed pollen 1, 0, 0, 0 plants.
Open pollinated seedlings of Therese Bauer have given me very large, repeat blooming, double flowered shrub roses. Therese Bauer is (Hansa X R. setigera) X R. setigera.
-------------------------------------------------------------------------
(( Therese Bugnet X OP) X OP) X (Bonavista X OP) 5, 1, 5, 2 plants.
(( Therese Bugnet X OP) X OP) X (R. kochiana X OP) 2, 0, 0, 0 plants.
R. kochiana is thought to be a diploid F2 of R. palustris X R. spinoisissima.
(( Therese Bugnet X OP) X OP) X mixed pollen 11, 5, 7, 0 plants.
(( Therese Bugnet X OP) X OP) X ((Delicata X OP) X (( Therese Bugnet X OP) X OP) ) 1, 0, 0, 0 plants.
(( Therese Bugnet X OP) X OP) X R-15 0, 1, 0, 0 plants.
(( Therese Bugnet X OP) X OP) X (Rugelda X R-15) 0, 0, 1, 0 plants.
From the above 2, it sure would be nice to see yellow flowers.
(( Therese Bugnet X OP) X OP) X (lost tag, blooms all summer, pink double, looks like explorer, rugosa cross) 0, 0, 6, 3 plants.
(( Therese Bugnet X OP) X OP) X William Baffin 0, 0, 1, 1 plants.
(( Therese Bugnet X OP) X OP) X (William Baffin X OP) 0, 0, 4, 0 plants.
----------------------------------------------------------------------
Will Alderman X (Basye's amphidiploid X OP) 2, 0, 0, 0 plants.
-----------------------------------------------------------------
(William Baffin X OP) X OP 22, 26, 24, 14 plants.
(William Baffin X OP) X Rosarium Unsterurn 0, 0, 1, 0 plants.
