为了在不可能进行如马铃薯与番茄杂交获得番茄薯那样的远缘植物间获得杂种,细胞融合是一项不可缺少的技术。由细胞融合获得的杂种因其来源被称为体细胞杂种。从番茄薯未能实用化可知,当初被寄以厚望的细胞融合技术,因时间的推移,其对育种的有效性受到了怀疑,研究工作也逐渐减少。其原因主要是,由原生质体进行再生是一项麻烦的课题,而且对象作物的选择方法较难;若选择双亲过分远缘的,则杂种很难再分化,或即使再分化也不稳定。 Cell fusion is an indispensable technique for obtaining hybrids between distant plants, such as tomato and potato, where it is impossible to cross the potato and tomato. Hybrids obtained by cell fusion are referred to as somatic hybrids for their origin. From tomato potato failed to practical, we can see that the original was sent to the hope of cell fusion technology, because of the passage of time, its effectiveness of breeding has been questioned, the research work also gradually reduced. The main reason is that protoplast regeneration is a troublesome subject, and the target crop selection method is more difficult; if the parents are too distant, then the hybrid is difficult to re-differentiate, or even redifferentiated instability.
