摘　　要：1980～1996年，利用太湖流域粳稻品种和从国内外引进的品种对其中江浙改良品种（系）和杂交育成品种（系）的系谱作了分析；对其抗稻瘟病性能的传递、性状的互补、杂种后代结构变化等问题进行了研究；探讨了太湖地区粳稻育种亲本选配规律；围绕正确选择亲本进行了早熟晚粳新品种的选育。从而提出了使太湖地方品种与现代改良品种相结合及类间差异大的江、浙改良品种相结合，以解决生物学产量下降和增高收获指数的矛盾、高产和优质的矛盾，逐步创造出太湖地区新一代的高产、稳产、优质粳稻改良品种的常规育种途径。The rice (Japonlca)cultivars from the Taihu valley,including Jiangsu and Zhejiang native varieties or improved varieties and domestic and foreign introduced varieties,were utilized in this study. The pedigrees of Jiangsu and Zhejiang improved varieties (lines)and cross bred varieties (lines)were analysed, and the transmission of rice blast resistance,complernentation of characters and structural variation in hybrid progenies were investigated. It is possible to select and breed new improved varieties with high and stable yield and excellent quality in the Taihu valley region through correctly selecting cross combinations.
