摘要
本文用培矮64s-05在三亚南繁时的逐日自交结实率资料和逐日均温和日长资料,根据育性量化模型鉴定该不育系在三亚的育性指标,并对培矮64s-05的光温反应特性进行分析。结合三亚30年(1959~19S8年)逐日气象资料和生育期预测模型对培矮64s-05南繁的最佳抽穗期和最佳播种期进行气候决策。
Peiai 64s-05, a temperature sensitive male-sterile line of rice, was grown at Sanya, Hainan Island. It's % of seedset were calculated daily, and the daily mean temperature and daylength recorded. Using these data, a quantified model for fertility was established and a fertility index for this male-sterile line at Sanya elabrated. The light-and-temperature reaction characteristic of Peiai 64s-05, was also analyzed. Using these model and index in combination with the daily meteorological data of 30 years(1959-1988), it is possible to make decision about the best heading date and the best seeding date for the seed multiplication of Peiai 64s-05 at Sanya.
