Hybrids of different narcissus species can be fertile by generating unreduced pollen

In this spring I found many plants of intersectional diploid narcissus hybrids in Spain which were fertile by generating unreduced pollen. This may be of great interest for daffodil hybridizers and plant breeding in general. More information you find on www.theo-sanders-daffodils.de.…

Fertility update – Div.10

It has been an extraordinary year here for bulbocodiums. The intra-sectional hybrids were great company over the winter. The inter-sectional hybrids are exploding in diversity and yielding all sorts of unexpected fertility. The foundation flower for this inter-sectional explosion is…

Fertility update – Div.7

The foundational fertile jonquil/main division hybrids are, of course, Limequilla Hillstar and Quickstep (and perhaps Gertrude Nethercote). The key problem is how to reliably introduce the genetics of the best main division hybrids into this group. It is now clear…

Fertility Update – Div. 5

There is no clear answer as to which hybrids best exemplify the characteristics of triandrus in standard sized daffodils. There seems to be a move away from hybrids with main division flowers (such as Ice Wings) to hybrids between triandrus…
