苎麻种子繁殖系数很大,是其优点;但后代分离变异大,严重影响产量和质量。试验表明,把生产中当家品种隔离自交,种子育苗后,植株形态、生产能力,纤维品质和抗性,高低参差不齐,一个品种可以分为多种类型。因此可以断言,苎麻无论哪个当家品种实质上都是杂合体,只有采用营养繁殖方法 The multiplication coefficient of ramie seed is very large, which is its merits; however, the separation and variation of offspring are large and seriously affect the yield and quality. Experiments show that the production of the inbred varieties of self-isolation, seedling, plant morphology, productivity, fiber quality and resistance, uneven, a variety can be divided into many types. Therefore, it can be asserted that, regardless of what kind of ramie is essentially a heterozygous hybrid, only by means of vegetative propagation
