水稻花药培养——单倍体育种,已成为水稻育种的一项新技术.但目前花粉单倍体植株仍依赖于自然加倍,加倍率一般仅30～50%左右,以致大量单倍体植株不能得到充分利用.金聿等仿照菸草上适用的组织法,在水稻叶鞘上曾获得过二倍体植株,但诱导频率低、诱导期长,实践上应用尚有一定困难.因此,进一步探讨单倍体植株体细胞培养染色体加倍技术,在理论和实践上都具有一定的意义.
Rice anther culture-haploid breeding has become a new technology in rice breeding.But pollen haploid plants are still dependent on natural doubling, doubling rate is generally only about 30 to 50%, so that a large number of haploid plants can not Has been fully utilized.Jin Yu and other imitation of tobacco on the application of tissue method, obtained on rice leaf sheath diploid plants, but the induction frequency is low, the induction period is long, there are still some difficulties in the practical application.Therefore, to further explore the haploid Body plant cell chromosome doubling technology, both in theory and in practice have a certain significance.
