最近,法国巴黎南大学植物改良实验室在试管里成功地培育出优质小麦。其做法是:从优质高产、抗病能力强的杂交小麦花粉中筛选出了5万个雄蕊花粉颗粒,把它们放在特定的培养基里,培育出533个没有母本的胚胎(染色体上有正常植物胚胎的一半),种植后生长出64株幼苗。为使这些幼苗具有与双亲同样多的染色体,对它们进行了特殊处理,有41株达到预期目的,18株进入产量试验,最后有2株获得了满意的结果,产量与现有优良小麦品种相当,而且有很好的同质性和稳定性。 Recently, the plant improvement laboratory at the Université Paris-Nancy successfully cultivated high-quality wheat in a test tube. The method is to screen out 50 000 stamen pollen grains from the high quality, high yielding and resistant hybrid wheat pollen and place them in a special medium to cultivate 533 embryos without the female parent Half of normal plant embryos), 64 seedlings were grown after planting. In order for these seedlings to have as many chromosomes as their parents, 41 had their intended purpose, 18 had entered the yield test and the last two had satisfactory results with comparable yields to the existing fine wheat cultivars , But also has good homogeneity and stability.
