辽宁省棉麻科学研究所为了培育兼抗黄、枯萎病的高产优质棉花新品种,1978～1980年进行了棉花种间杂种胚离体培养的研究。经过三年工作,已获得了野生棉瑟伯棉(G.thurberi)、中棉(G.arboreum)、代维森棉(G.davidsonii)与陆地棉(G.hirsutum)的种间杂交胚子一代种子和具有双亲性状的子二代植株。这些植株生长发育正常,并已开花结铃。这项研究是采用炉渣加营养液培养离体胚的方法进行的。它突破了过去用试管培养基培养离体胚的老方法,明显具有以下一些优点:
In order to cultivate new cotton varieties with high yield and good quality, which resistant to yellow and fusarium wilt, Liaoning Cotton Institute of Maize Research was conducted in vitro from 1978 to 1980. After three years of work, it has been a generation of interspecific hybrid embryos of G. thurberi, G.arboreum, G..davidsonii and G. hirsutum, Seed and second-generation plants with parental traits. These plants grow and develop normally, and have flowering knot. This study was conducted using a method of culturing an in vitro embryo with a slurry plus nutrient solution. It broke through the old method of culturing ex vivo embryos with test tube media and clearly has the following advantages:
