FAO/IAEA 联合处植物遗传育种部对一部分选择项目进行经济资助,重点放在半矮秆谷类作物突变体、热带块根茎作物体细胞突变体及共生固氮作用有所改善的粒用豆类突变体上,同时对离体培养技术发展到实用阶段给予关注。在1985年8月19日—28日召开的国际讨论会及研究协调会议上,对离体培养技术在突变育种中的作用进行了评价,其中包括:“微繁殖”的利用价值、离体培养选择技术的局限性、多倍体的潜力、体细胞克隆变异、体细胞突变的不确定性及基因工程展望等(会议文集已出版——译者注)。
The FAO / IAEA Joint Division of Plant Genetics and Breeding provided financial support for a number of selected projects, with emphasis on semi-dwarf cereal crop mutants, tropical rhizome somatic mutants and symbiotic nitrogen fixation. At the same time, attention should be paid to the practical development of in vitro culture technology. The role of in vitro cultivation techniques in mutation breeding was evaluated at the International Symposium and Research Coordination Meeting, August 19-28, 1985, which included the value of “micropropagation”, in vitro culture Limitations of selection techniques, potential for polyploidy, somaclonal variations, uncertainties in somatic mutation and genetic engineering outlook.
