The fertility of species and named daffodils.
Today I crossed these two plants to get nice seedlings. Some of these shall produce unreduced pollen which can be of great interest for combining them with tetraploid standard daffodils. A project for about 12 years which will be successful when the crosses develop seeds. Theo
Crosses of viridiflorus hybrids like Emerald Sea with the diploid N. cantabricus from Spain near Puertollano are easy to realize and grow well in my greenhouse. The bulbs multiplicate better than crosses of N. triandrus pallidulus with Emerald Sea. The progeny…
For these daffodils fertility theoretically should not exist or be rare, but in reality we find many fertile plants. Poeticus hellenicus (from Carlos van der Veek) for example is autotriploid and with 70 % sprouting pollen highly fertile. The pollen grains are…
It has been a good year for seed on the narcissus/pseudonarcissus triploids, mostly crossed with tetraploids. Hopefully, in a few years, it will be clear how effective this policy is for producing fully fertile tetraploids. A sibling of Glenbrook’s Sad…
The quest for fertile inter-sectional division 5’s is progressing very slowly here. The policy of putting sterile triploids onto fertile inter-sectional tetraploids is being pursued but very few seeds have been obtained. Mission Bells was very reluctant this year but…
A few interesting plants have set seed this year further confirming the potential of intersectional bulbocodium hybrids. There was an unfortunate mistake planting the 2011 seedlings. They were shallow planted because it was late and some had sprouted. The dry…
