继新关宏夫等1968年获得水稻花粉植株后,我国科学工作者自1970年初起应用花药离体培养进行了水稻等作物的遗传育种研究工作,当年即获得一批花培完整植株,以后在短期内先后培育成一些栽培稻(O. SativaL.) 的新品种或品系,有的已大面积用于生产,有的正在进行生产性鉴定和示范试种. 尽管如此,作者认为在当前开展大量的花培育种工作中,所用试剂很多,操作技术繁琐,在一定程度上影响了花培育种工作的进一步开展.为了使这项新技术适合我国的实际情况,降低成本,提高效益,使之不断趋于合理、完善,1975年以来,我们进行了一些试验,现将部分结果报道如下.
Following the new Guan Hongfu access to rice pollen plant in 1968, our scientists from the beginning of 1970 germplasm application of in vitro culture of rice and other crops of genetic breeding research, that is, get a batch of flower culture complete plant, after the short-term New cultivars or strains of cultivated rice (O. sativa L.) have been cultivated in succession, some of which have been used extensively for production and some of them are undergoing productive identification and demonstration trials. Nevertheless, the authors consider that a large number of In the process of flower cultivation and breeding, there are many reagents used and cumbersome operation techniques, to a certain extent, this has further affected the further development of flower cultivation and breeding.In order to adapt this new technology to the actual conditions of our country, reduce costs and improve benefits, In a reasonable and perfect, since 1975, we conducted some experiments, some of the results are reported below.
