One year ago I published a picture of N. x xanthochlorus ( N. cavanillesii x N. viridiflorus) on Daffnet. This year three bulbs will flower. Two flowers allready opened (see photos). N. x xantthochlorus is allotetraploid and therefore seed- and…

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 of Classic Gold, Apollo Gold, and Little Laine
Clay Higgins wrote on June 14 that he got seed from the open pollination of Classic Gold. This is a cross of N. bulbocodium conspicuus, which should be hexaploid, and N. rupicola which is diploid. Such a combination normally is unfertile. But some of these XXXY-…

Pollen Volume and Chromosome Content of Daffodils; Possibilities for hybridizing 2 and 3
During March 2013 I found some different yellow bulbocodiums in Potugal and Spain. From observing the pollen volume I think that four plants are diploid, two are tetraploid, and one is hexaploid. I found out that most diploid species can…
