近几年来,水稻孤雌生殖研究和应用取得了一定的进展,这对加快获得纯合杂种,缩短育种年限,是具有一定意义的.但目前此项研究,存在着诱导率偏低的问题.为此,我们进行了不同诱发剂及其使用时期的试验,以期找出最佳诱发剂和最适宜的处理时期,提高其诱导效果. In recent years, some progress has been made in the research and application of parthenogenesis in rice, which is of certain significance for accelerating the obtaining of homozygous hybrids and shortening the breeding years, but so far there is a problem that the induction rate is low in this study. To this end, we carried out different inducers and their use of the period of the experiment, in order to find the best inducers and the most appropriate period of treatment to improve its induction effect.
