摘  要:
通过对龙特甫A在不同年份、不同播种期、实生稻与再生稻的花粉育性观察,结果表明:年份间、播种期间、实生稻与再生稻间的育性差异均达到显著水平。龙特甫A的育性除受本身的核质遗传关系影响外,环境条件(温度和日照)对育性也起重要作用.

摘  要:
The observation of pollen fertility of seeded- rice and ratooned-rice from the same plant was conducted under conditions of different years and different sowing dates of the same year. The results indicated that there are significant difference of male-fertility between different years, different sowing dates and seeded-rice and ratooned-rice of the same plant. The fertility of Longtepu A cms 1ines was also much affected .by the enviroment factors (of temperature and sunshine ) as well as the cytoplasmic-nuclear itsefl.
