摘　　要：分析了江苏中部地区气象条件与两系杂交稻制种两个安全期的关系 ,认为苏中地区两系制种不育系的育性转换敏感期安排在 7月下旬与 8月上旬为最佳 ,最佳的抽穗扬花期在 8月中旬。提出以实效积温为依据安排父母本的播种期。The selection of seed production season of two-line hybrid rice (TGMS) was analyzed based on the climatic data of 30 years from 1970 to 1999 in Taizhou, the middle areas of Jiangsu province. The sensitive stage of fertility alteration of TGMS line was between the end of July and the beginning of August. The optimal initial heading date for the seed production of two-line hybrid rice should be in the middle of August. A method for arrangement of the seeding interval between the two parents with the effective accumulated temperatures was applied.
