2. Viviparity in Pairat's Hardy Hybrids

I began hybridizing hardy waterlilies in 2003 by using various pod and pollen varieties and one of them is N. mexicana. My goal has never been to create hybrids that can be viviparous. I have created 28 hybrids of N. mexicana (elaborated in Should Nymphaea mexicana be a Pod or a Pollen Parent?) with current status in the following table (Table 2) showing that there are not viviparous hybrids among these creations.

Currently I have created hybrids from various pod and pollen parents, a total of 555 plants. Viviparity has unexpectedly occurred in this group, even though there were no hybrids of N. mexicana or N. 'Colonel A.J. Welch' involved. Vivipararity has occurred in five plants (Table 3), a 0.9 % chance when calculated from all the hybrids.

When considering the pod and pollen parents of the hybrids from table 3, it can be seen that the five hybrids have N. 'Perry's Fire Opal' influencing the possibility of viviparity; it is the same as N. 'Lily Pons' that has N. 'Perry's Fire Opal' as the pod parent even though there has never been any vivipararity with N. 'Perry's Fire Opal' before.
     

Viviparity rarely happens in hardy waterlilies so the hope of reproduction through viviparous plants is inefficient when compared to conventional means that give faster results. This is in contrast with reproduction from leaves of viviparous tropical day bloomers, which is easy and more appropriate.

This is an update of the information on viviparous hardy waterlilies. It can be seen that viviparity does not only come from N. mexicana or N. 'Colonel A.J. Welch', but is also possible with offspring of N. 'Perry's Fire Opal' or other cultivars in the future.

More about Viviparous Hybrid #3

In April of 2007, viviparous hybrid #3, clustered in a big set, achieved viviparity in five different flowers at the same time. Closer observation suggested that flowers that were viviparous were usually strange and crippled, reproducing on the day of blooming. The viviparity of this hybrid happened only once and has never happened again.
