In order to get a Blue Hardy Water
Lily, many red flower cultivars of nymphaea subgenus have been pollinated by
blue flower water lily of the brachyceras subgenus. A successful crossing yielded only one pod or fruit with 244
seeds, from which only 39 seeds germinated, yielding 20 good hybrid
plants. They have different
distinct flower characteristics with rather red, pink as well as white and blue
colours. The prominent hybrid
plant with beautiful blue-purple flower has been named as Siam Blue Hardy and
proved to be a hybrid between nymphaea and brachyceras subgenera by the
PCR-RFLP markers, as well as other inherited plant characteristics, for
example, ovary carpel, leaf, rootstock or rhizome.
