海带初次自交的小实验表明,自交对海带幼孢子体的形成和生长发育有某些不良的 影响。 根据上述材料和其他有关的材料,我们认为目前养殖的海带种群是杂种,含有一定的隐性遗传,因此初次自交就产生某些有害的影响。但自交有害不是绝对的,预料通过累代连续的自交和选释可能培育出在经济上富有价值的优良品种和若干能产生杂种优势的自交系。 Small experiments with kelp for the first time showed that selfing had some adverse effects on the formation and growth of kelp. Based on the above materials and other related materials, we consider that the currently cultured kelp population is a hybrid that contains some recessive inheritance and therefore has some detrimental effects on the first selfing. However, it is not absolute that selfing is harmful, and it is expected that economically valuable fine varieties and inbred lines capable of generating heterosis may be bred through successive generations of selfing and selection.
