A nice selection of 7, 8 and 10’s are flowering here at the moment.

The peachy color of 14_04MJ only develops when picked and brought inside.

      

Some jonquilla will flower in the autumn under the right conditions. This one was kept in the shade over summer.

18_06B is not exactly in flower at the moment. A bird tried to see if it was edible yesterday before it could develop properly.

    Lawrence, many different and very nice seedlings. For the flower in the third picture I suppose it has genes of N. viridiflorus and N. cyclamineus?

    Hi Theo,

    17_13MJ is meant to be (Viriverse x Theoquil) x (Virition x Virivest) but it is quite different to its siblings. A Viriverse x (fernandesii  x cyclamineus) was planted nearby so there is a some chance they could have been mixed up. It has passable fertility.

    These hybrids can be bred for reflex without the aid of cyclamineus. 15_01MJ is Virition x (Viriquilla x Virivest). Not surprisingly, I have crossed these two flowers with each other.

    The perfectly fertile Viriverse x Theoquil (12_03MJ) first flowered late April 2012, just a couple of months after you published your views on the potential of hybrids such as Theoquil  – which is why I named it ‘Theoquil’. While checking these details I noticed this article in DaffLibrary
    http://dafflibrary.org/wp-content/uploads/Sanders-Theo-Looking-at-Pollen-The-Daffodil-Journal-Dec-2009.pdf where you make the same point. Is the 1990 date correct, because it also says it is from a Daffnet posting?

    I do enjoy your photos, and that is a great article. Thank you for sharing! I think a reprint is in order.

    The 1990 date can’t be right, though, as the article itself references the December 2000 issue. I’ll have to do some sleuthing.

    In any case, your seedlings are just beautiful.

    Lovely seedlings, Lawrence.

    The 1990 date is incorrect.  The article was in the December 2009 Journal.  I’ve corrected that in the posting (Cytology), but can’t get the incorrect reference out of the search engine.  I’ll talk to Ben.

    Lawrence,

    I took the liberty of updating your comment on May 26, 2018 at 1:16 am with a new URL link to Theo Sanders’s 1999 article because I could not find it in a 1990 journal.

    I hope this helps and please pardon me if I misunderstood http://dafflibrary.org/wp-content/uploads/Sanders-Theo-Looking-at-Pollen-The-Daffodil-Journal-Dec-2009.pdf

    Ben

    Thanks Jolene, Mary Lou, and Ben,

    If I’d actually read the article thoroughly before commenting I’d have seen the mention of 2008. Thanks for fixing the title and providing the link. (It just needs updating in the library itself.)

    I am puzzled as to why I didn’t notice the significance of this article in 2009. I’m sure I didn’t because I didn’t return to triandrus hybrids until 2012 – 3 years lost!

    The speculation that sterile jonquil/main-division hybrids (NNJ) can produce NJ gametes was doubly confirmed here last year. 17_70MJ is a very nice fertile reverse bicolor from [Limequilla x (Hillstar x Gertrude Nethercote)] crossed with the triploid Limeade x jonquilla. This developed into an intensely reversed bicolor with excellent substance.

    As a seedparent the triploid ‘Yazquil Angel’ (Moomba x jonquilla) has also produced a fertile hybrid. (Apologies for not registering these flowers!)

    I think we can confidently say that, thanks to Theo’s observations, the problem of producing fertile jonquil hybrids is solved.

    A few dubius/main-division hybrids were successfully intercrossed last season. Does this kind of cross produce fertile hybrids?

    Lawrence,

    For crosses of standard daffodils with N. viridiflorus I used the type in the first picture. Clones with reflexed petals and a split corona as in the other two photos should also be applied in the future.

    In 2009 I was sure to have many seedlings which proof my theory of the fertility of allotriploids. But most of them were indeed self pollinations of jonquilla hybrids. The extraordinary frost in 2012 further destroyd many seedlings. I am optimistic for the future, but with your crosses to proof my theory you have been much more successful than I and I am very fond of this demonstration.

    Your crosses of dubius/main-division hybrids should be fertile. In the best case they are allotetraploid with high fertility. If some tazetta chromosomes are integrated into the gametes also most seedlings should have fertility, but it will be reduced, except for an embryo with 14 standard, 14 assoanus, and 22 tazetta chromosomes.
