摘　　要：【目的】追溯海7124的选育过程,通过性状演变分析,明晰品系特征,为深入挖掘海7124在棉花遗传育种与资源利用中的价值提供参考。【方法】分析海7124选育过程中原始材料、相关株行材料、决选单株材料的生育期、结铃性、产量、纤维品质、抗病性和株型等性状信息。【结果】海7124品系选育始于1959年由埃及引入的原始材料米努非,经过10代的系统选育而成,于1965年获得关键单株65-3049-6,最终以1974年获得的优良株系7124定名。系统选育得到了生育期明显缩短的海7124品系。同时,原始材料米努非与海7124相关溯源材料的优异纤维品质、丰产、较强黄萎病抗性等优良特性得以保留,还塑造了紧凑株型。【结论】海7124品系源自原始材料米努非,系统选育促进其早熟,保留了优质、丰产、抗黄萎病等特性。[Objective]The purpose of this study was to trace the breeding process of Hai 7124,and clarify the characteristics of strains thorough analyzing the evolution of several traits,so as to provide reference for further exploring the value of Hai 7124 in cotton genetic breeding and resource utilization.[Methods]By consulting the historical research archives preserved by Institute of Industrial Crops,Jiangsu Academy of Agricultural Sciences,the growth period,boll setting capacity,yield,fiber quality,disease resistance,plant architecture and other informations of the original materials and the selected breeding materials involved in the selection process of Hai 7124 were analyzed.[Results]The breeding of Hai 7124 began in 1959 with the introduction of the original material named Menoufi from Egypt,and went through ten generations of systematic selection.The key individual plant 65-3049-6 was obtained in 1965,and the selected line numbered 7124 with excellent characteristics was obtained in 1974,which named Hai 7124.Systematic selection not only promoted the early maturity of Hai 7124,but also preserved the excellent characteristics of the original material Menoufi and the related breeding materials,including good fiber quality,high yield,and strong resistance to Verticillium wilt.Additionally,it contributed to the formation of compact plant architecture.[Conclusion]Hai 7124 was derived from the original material Menoufi.The systematic selection promoted early maturity,and retained excellent traits,such as good fiber quality,high yield,and resistance to Verticillium wilt.
