粳型光温敏核不育系N5088S高产直播繁殖技术研究

Research on High-Yield Propagation Techniques of Direct Seeding Japonica PGMS Line N5088S

根据粳型光温敏核不育系N5088S在自然短光照条件下经不同温度的处理和不同直播期、直播量的繁殖试验结果,分析了武汉地区近20年来8月下旬至9月中旬的日平均温度,提出了粳型光温敏核不育系N5088S在武汉地区的最佳播种期和高产稳产的直播繁殖技术。

According to the propagation test results of Japonica PGMS line N5088S treated with different temperature under natural light,different sowing time,different seeding rate,the daily average temperature between late August and mid-September in Wuhan in recent 20 years was analyzed.The best sowing time and high-yield propagation techniques were suggested for the propagation of N5088S in Wuhan.
