| Abstract | Studies on the intersubgeneric pollination of genus Nymphaea to achieve the goal as a Blue Hardy Waterlily. Five cultivars from the subgenus Nymphaea were used as the pod parents, selected from a sample with a good history of smooth fruiting, beautiful and rich flowerings. As for the pollen, the subgenus Anecphya and Brachyceras ware used, specifi-cally the blue flowering ones in the hope of transferring the genetic traits onto the offspring. Two of the pollen parents were Anecphya and twenty were Brachyceras. The study was conducted at the nursery, Nonthaburi, Pathum Thani provinces and Kasetsart University during 2003-2007. According to the pollination of subgenus Nymphaea with subgenus Anecphya, the test results were unsuccessful because of both subgenus were large different in the chromosome numbers. On the other hand, the pollination between subgenus Nymphaea and Brachyceras yielded one successful pod which were cultivated into 20 plants. The characteristics of hybrids had been categorized by their colours and divided into two groups namely the pink group with 17 hybrids and the blue group with 3 hybrids. In the blue group, there was one which had a beautiful blue-purple flower. Which had also been proven to be a hybrid between Nymphaea and Brachyceras the use of the molecular marker method (PCR-RFLP Marker) and morphological marker method. The important characteristics of the hybrid obtained are likely that of a Hardy, making the blue-purple the new colour for the Hardy. The hybrid is then called to be the First Blue Hardy Waterlily in the world and given the name Nymphaea 'Siam Blue Hardy'. |
