利用花药培养单倍体植株并作为一新的育种手段,已是现代广为应用的一项新技术。我国应用这项新技术,在烟草、茄子、小麦和水稻等作物的育种上取得进展。但目前在籼稻花培方面,由于绿苗诱导频率偏低,育种进展不快。为了提高籼稻花粉植株的诱导率,我们根据动植物组织培养或细胞培养均要求掌握适当密度的论点出发,从一九七六年开始, The use of anther culture of haploid plants as a new means of breeding has become a new technology widely used in modern times. My country is applying this new technology to make progress in the breeding of crops such as tobacco, eggplant, wheat and rice. However, flower cultivation in indica now, due to the low frequency of green seedlings, breeding progress is not fast. In order to improve the induction rate of indica rice pollen plants, based on the argument that animal and plant tissue culture or cell culture require proper density, starting from 1976,
