摘要:

为解决羊栖菜养殖生产需要的优良种苗，经过10多年努力，采用有性繁殖方式，进行定向选育，获得羊栖菜“鹿丰1号”。该优质羊栖菜的主要性状是：枝叶粗壮繁茂、气囊产生早、颗粒大、产量高，经过8年的养殖及检验，目标性状表现稳定，附苗总面积达到1 912 m2，培育出苗59.3 hm2，总产量383.746 t，平均产量6 471 kg/hm2。目前，该选育的羊栖菜已在温州地区的洞头县和苍南县以及山东部分海域进行了养殖中试，选育性状表现稳定，养殖产量高，为羊栖菜良种化的实现打下基础。

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.
