| 摘 要： | 原生质体再生植株发生变异的现象较为普遍，已涉及到很多作物，变异的类型较多，主要有染色体变异、形态和农艺性状变性、抗性变异等，产生变异的机理主要有遗传和生理两方面，此类变异有其优点和不足，但无庸置疑的是原生质体再生植株遗传变异为植物育种提供了大量可供选择和利用的材料。

| Abstract: | It is common that variation was observed in the protoplast-derived plants, which involves many plant species. There are several kinds of variations such as chromosome variation, morphological and agricultural trait variation and resistance variation. The corresponding mechanism for the variation is characterized with genetic and physiological aspects. The variation has its own advantages and disadvantages.It has been documented well elsewhere that variation in the protoplast-derived plants paves way for plant breeding. |
