五十年代末,我们进行了海带遗传育种的研究,了解到海带某些经济性状的遗传规律,并培养出几个性状此较稳定的优良品种,这些品种已在生产上发挥出较大的作用。 但是,我国不是海带的原产地,海带种类相当贫乏,只有一种L.japonica,这给海带遗传育种的研究带来很大局限性。为解决原始材料不足,加快我国海带遗传育种工作的速度,在1981年4月,中国科学院海洋研究所由加拿大引进了长腿海带L.longicruris。掌状海带 In the late fifties, we carried out a study on the genetic breeding of kelp, and learned the genetic laws of certain economic traits of kelp, and cultivated several relatively stable fine varieties of these traits, which have played a greater role in the production . However, our country is not the origin of kelp, kelp species is rather poor, there is only one L.japonica, which kelp genetic breeding cause a lot of limitations. In order to solve the shortage of raw materials and speed up the genetic breeding of kelp in China, in April 1981, the Institute of Oceanology of Chinese Academy of Sciences introduced L. longicruris from Canada.
