利用离体花药培养花粉单倍体育种技术培育作物新品种,是细胞工程领域的一项开发性技术。利用这项技术,可以大大缩短作物育种年限,加快育种进程,受到国内外广大育种工作者的重视。据报道,1976年以来国内外已利用这项技术培育出不少小麦、水稻、油菜、烟草、石刁柏、三叶橡胶等新品种。甘肃省农业科学院粮食作物研究所单倍体育种组自1973年开始进行春小麦花粉单倍体育种研究。春小麦新品系764,是该室1976年获得的花
In vitro anther culture of pollen haploid breeding technology to cultivate new varieties of crops is a developmental technology in the field of cell engineering. Using this technology can greatly shorten the crop breeding years, speed up the breeding process, by the majority of breeding workers at home and abroad attention. It is reported that since 1976, this technology has been used at home and abroad to breed many new varieties of wheat, rice, rape, tobacco, asparagus, clover. Gansu Academy of Agricultural Sciences Institute of Food Crops haploid breeding group since 1973, the spring wheat pollen haploid breeding research. The new spring wheat line, 764, was the flower that the room received in 1976
