摘要： 采用遗传上具有较大的差异、性状上互为补充的多个亲本进行复合杂交，将杂种后代置于不同环境条件下进行交替选择，中选稳定株系再置于不同逆境条件下进行抗逆性鉴定，最后将优系混合繁殖。利用上述方法于1977年进行杂交组配，1986年选育棉花新品种石711.该品种于1992年被河北省审定，1993年被天津市审定，1994年被国家审定并被命名为GS冀棉17.GS冀棉17在1990~1994年累计种植面积35万hm²。

Abstract: A Composite crossing way was carried out by using many parents,which had many disparities in genetics and reciprocity in characters.The filial generations were alternately selected under different adverse environments.The adverse resistances of the stable lines were characterized under different adverse growing conditions.The better lines were mixing reproducted.According to the method,intercross was carried out in 1987 and a new cotton variety Shi 711 was produced in 1986.It was examined and approved by Hebei province in 1992 and by Tianjin City in 1993.It was in 1994 that it was named as GS Jimian 17 by the Nation.The planting area of the variety added up to 350 thousand hectare during 1990~1994.
