摘要
通过杂交水稻不育系中青棵的来源调查分析,认为在排除了机械混杂和生物学混杂的前提下,青棵的出现主要来自不育系本身的育性变化。基于这一认识。
The origin of late-ripe plants which are late in maturity and hardly set seeds normally in CMS lines of rice was studied. After the exclusion of biological and mechanical admixtures, the rusults showed that the late-ripe plants in CMS lines were mainly originated from partial restoration of self-fertility of CMS lines. Based on this, the corresponding measures could be taken to remove the late-ripe plants in CMS lines.
