| 摘 要： | 设置长、短日照和高、低温4种环境,分析了我国长江中下游和华南地区早籼水稻品种和杂交早籼骨干亲本共19份材料的抽穗期光温敏感性及基本营养生长性。结果表明,这19份早籼材料(包括杂交稻亲本)都表现出弱感光性,其中16份材料对温度比较敏感。这些早籼材料的基本营养生长性整体较弱,但是个体间表现出一定的差异。抽穗期长短与每个材料的基本营养生长性呈显著线性相关。利用一套抽穗期主基因近等基因系对这些早籼材料抽穗期基因型进行了分析。结果表明,所有早籼材料均带有隐性非感光位点hd2,大多数早籼材料都带有显性早熟基因Ef-1,而在Se-1和E1两个主效感光基因位点,所有早籼材料不带或只带有一个感光等位基因。这些结果从基因型角度揭示了早籼材料具有弱感光性和较强感温性,是其适合在我国华南双季稻作区和华中单双季稻作区作早稻种植的原因,为早籼水稻品种的选育及推广提供了重要依据。 |

| Abstract: | Heading date is one of the most important traits for the adaptation of rice to different cultivation areas and cropping seasons. Early season indica rice cultivars play an important role in rice production in China. Heading dates of 19 early season indica rice cultivars and hybrid rice parental lines from the middle-lower region of the Yangtze River Valley and South China were investigated and their sensitivities to photoperiod and temperature were analyzed. Among the 19 rice materials, 16 were sensitive to... |
