摘　　要：以 1 997～ 1 998年度参试的 1 3个新不育系为材料 ,依据在三亚市、武汉市和贵阳市三个地理生态区 ,进行分期播种试验所获得的套袋自交结实率和温度、日照长度资料 ,采用光温因子分级和育性量化模型等两种分析方法进行育性指标的生态特性研究。Fertility index has been evaluated using s taging-sowing experimental data on sacked self-fruitful rate, air temperature a nd sunshine hours for 13 new genic male steril (GMS) rices from three geographic al ecological places ( Sanya of Hainan, Wuhan of Hubei and Guiyang of Guizhou). The ecological features of the index are investigated both by grading light-tem perature and by applying a quantitative fertility model respectively and their p ractical importance are discussed finally.
