| Abstract: |
| Hizikia fusiformis (Harvey) Okamura is a kind of important brown macroalga for cultivation in China. For sustainable development of commercial farming of H. fusiformis, a stable, efficient and practical seedling production technique and good strains needs to be developed. Selection and breeding of excellent strains is the trends in commercial seaweeds cultivation in China, especially for H. fusiformis (Harvey) Okamura. To meet the needs of good seeding supplying in Hizikia culture, good quality and high yield of Hizikia “Lu Feng No.1” was selected and bred continuously by sexual reproduction for over 8 years practice. Through many years of breeding and cultivation tests,“Lu Feng No.1” showed the following main characters, the thallus is thick and flourishing; the large neumathodes form earlier and with high yield. So far, the selected strain has been cultivated in Cangnan and Dongtou County of Wenzhou and in some areas of Shandong province, and the selective characteristics were stable and the production was high.The success in breeding of “Lu Feng No.1” has provided a basis for the application of good strains in H. fusiformis cultivation. |
