Re: Self-Incompatibility

you guys complicate these things to much, going into great lengths on definitions and theories. Just simplified it as, it can't pollinate itself due to a hormone block, but a plant of the same species, growing nearby because it is individually different, can pollinate and vise versa. A lot of plants...

Re: Under-utilized species you feel might have merit

Thanks Jonathan the R. willmottiae X R forrestiana has been a blessing for me.
Thanks Phil, the Hybrid virginiana's do well when crossed with dioloids, this one is shaded by R tunquinensis and the Hybrid R. davidii's and grows very happy with those conditions.

Cheers Warren

Re: Under-utilized species you feel might have merit

Here are a couple.
The first is seedling S1 T5 (Rosa tunquinensis X Lorraine Lee) repeat flowering
The second is a species hybrid which has provided me with a good bridging rose (R.willmottiae X R.forrestiana)

Re: yellow rugosas

David it may become fertile if it is grown in higher zone rating of 8 or 9 . see if anyone in these zones would like to take it on.

Re: Canina Chromosome pairing

"we may ask why Synstyles have not (apparently) participated in the formation of polyploid species."

A very good question, in the last couple of years I have been using roses from Synstylae or its offspring. Even at the level of F3 you can still see some influence of Synstylae stigma's.

Canina Chromosome pairing

A quick question.

With R. canina varietites and their weird and wonderful chromosome configuration, do the bivalents only have the influence of the plant growth and characteristics or do the univalents have some say in the matter as well.

Re: 2018 Germinations

Germinated (Sympathie X R.virginiana) X (Fru Dagmar Hastrup X Enfant des Ardenne)

This should be interesting Hybrid kordesii, R.virginiana, Rugosa and Hybrid multiflora combination.

Re: early culling of species seedlings...

that is the reason I mainly use species as pollinators, they and rugosa's shed their pollen at a very early stage in bloom formation.

Re: Strong Characteristics which are passed down the line

Don I don't mind thorns, but I am working on some thornless lines. I did this cross http://www.helpmefind.com/gardening/l.php?l=2.64468 which ended up thornless, a lot of Noisettes are thornless and have good results.

Re: Strong Characteristics which are passed down the line

almost all seedlings bred from this line descending from "Maigold" produce these thorns along with that linseed oil fragrance. Xanthus was the only one to have sweet fruity perfume, mind you the thorns were well represented.

Strong Characteristics which are passed down the line

I have found by using certain cultivars or species , certain characteristics can be strongly represented. This is seedling S37 T64 which is 4 generations away from R.spinosissima. As you can see the thorns have prevailed.

Re: Any merits to R. woodsii ultramontana?

Phil the vinegar is acid , peroxide is base, they probably counteracted each other, therefore nothing was achieved.
