作物的花粉培养单倍体育种技术,是六十年代发展起来的世界先进育种技术。我国的籼稻花粉培养,自一九七二年广东省植物研究所突破绿苗关后,近二、三年来普及较快,但对于花粉愈伤组织的诱导频率和绿苗分化频率仍然远远不及烟草或其他植物,也低于粳稻,除未能合成更理想的培养基外,在培养技术上还存在着几个难关未能突破,如白化苗多,愈伤组织“小老头”多,幼苗(芽)夭折多,冬季就地移苗死亡多,如何提高花粉培养效率,获
Crop Pollen Culture Haploid breeding technology is developed in the sixties the world’s advanced breeding technology. The pollen culture of indica rice in our country has been popularized rapidly since 1972 when the Guangdong Institute of Botany broke through the green seedling clearance, but the frequency of induction of pollen callus and the frequency of green shoot differentiation are far behind Tobacco or other plants, but also lower than japonica rice, in addition to the failure to synthesize more ideal medium, there are still several difficulties in culture technology failed to break through, such as more albino seedling callus, “little old man” more seedlings (Buds) die more, the death of local Miao death in winter and more, how to improve the efficiency of pollen culture, was
