人类在改造高等植物的事业中,受到太多的限制。例如,通过花粉传粉进行有性杂交,会受到物种亲缘关系的限制;通过原生质体融合进行体细胞杂交,也受到亲缘关系和杂交细胞分化困难的限制;通过转基因技术(也称基因工程)改良植物,又受到绝大多数植物性状不是由一个基因而是由多个基因综合调控的限制,这些制约的因素长时间阻碍着人类更好地利用和改良高等植物。
在这种背景下,高等植物染?体杂交技术及其学术理论应运而生。
在一定的条件下,将外源的异源的染色体及其片段导入受体植物的细胞,两种不同的染色体DNA因重组而发生杂交,从而在受体细胞中形成杂交染色体,这样就形成具有杂交染色体的新型细胞,这种杂交染色体细胞通过分化和培养,就可以获得具有杂交染色体的新型植物,本书将这些植物称之为染色体杂交植物。
