Abstract

By bringing up continously clone gametophyte of Laminaria,make clone cells processing ismade continuously protonema clone gam etophyte is shattered,using twain system crossbreed culling cultivate breed heterosis.The expermient result shows that the increasing-weight rate per day of female and male clone gametophyte of Laminaria is 14.03% and 13.87%,After 42 d cultivating,their weight increasing proportions are 6.9 and 6.8 tmies.The expermient of seedling clone of Lam inaria is a lso done.Under the proportion of 2.1(cells count),female and male clone cultures 16 d,the ovulate rate is 100%.After 60 d cultivated,young sporophyte slength is 2~3 cm,by culturing in the sea,one crossbreed breed is selected.
- Laminaria,
- clone gametophyte,
- twain system crossbreed,
