摘要
水稻花期高温引起的不育危害,具有发生可预测性低、作用局限于特定部位、致害程度严重等特点.本文就水稻花期高温不育问题,在发生时间、致害温度、品种反应差异、作用机制、鉴定方法以及抗性性状遗传等方面作了综述.并结合在日本的相关研究及对中国江汉平原杂交中稻花期高温危害发生的气候条件、品种差异等的初步分析,提出了该领域研究目前存在的关键问题和主要解决途径.
High temperature-induced rice sterility at anthesis is characterized by its organ-specific, high severity, and low predictability of occurrence. This paper summarized the research advances in rice sterility at anthesis under high temperature, gime, differences in responses among varieties, including occurrence period, injury temperature redamage mechanisms, evaluation methods, genetics of tolerance traits, and molecular biology of anther dehiscence and pollen abortion, etc. Based on the relevant researches in Japan as well as the studies in Jianghan Plain, China on the climate conditions under which some key points and temperature -induced options for the further damage on middle-season rice hybrids occurred.
