Abstract

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 to100%; the length of juvenile sporophyte after 40 d breeding is 2-3 cm.By farming on the sea,a hybrid combination is primarily screened.
