摘要

After continuous breeding gametophyte of Laminaria, then breaking protonema, heterosis seedling is got by bilineal hybridization. The result shows that the weight-increasing rate of female and male gametophyte clone cells are 14.03% and 13.87%, after 16 d crossbreeding, the rate of ovulation is up tolOO%; the length of juvenile sporophyte after 40 d breeding is 2～3 cm. By farming on the sea, a hybrid combination is primarily screened.
