苎麻是我国特产,也是重要的纺织纤维原料。它是花器官极小的常异交作物,又是靠无性繁殖的多年生宿根作物,因此苎麻的有性杂交育种十分困难,历史上都是靠选择优良植株育成品种,并通过无性繁殖扩大种植和保持其纯度的。为了打破苎麻育种上的这种被动、落后的局面,我们用花培技术探讨苎麻单倍体育种的可能性,以育成纯合的高产、优质、抗性好的新品种,并在隔离条件下生产纯度高的良种种子,供生产上迅速推广之用,从而革新现有的苎麻育种和繁殖方法,为快速有效地育成优良品种开辟一条新途径。 Ramie is our specialty, but also an important textile fiber raw materials. It is a flower extremely small often outcrossed crops, but also by clonal reproduction of perennial crops, so ramie sexual hybrid breeding is very difficult, historically rely on the selection of fine plants bred varieties, and through asexual reproduction to expand planting and Maintain its purity. In order to break this passive and backward situation on ramie breeding, we explored the possibility of ramie haploid breeding by using flower culture technique to breed homozygous new varieties with high yield, good quality and good resistance, and under the condition of isolation Production of high purity seeds of seeds for rapid promotion of production used in order to innovate the existing ramie breeding and propagation methods for the rapid and effective breeding of fine varieties to open up a new way.
