摘 要 ：1973年,本院发现芥菜型油菜雄性不育株后,经连续几年研究,1975年育成了欧新 A 不育系,欧新 B 保持系和74243—6恢复系,实现了芥菜型“三系”配套。多年来连续测定表明,育成的芥菜型“三系”表现育性稳定,欧新 A 不育系的不育株率达100%,单株自交结实指数平均在0.000—0.103之间。恢复株率为99.54～100%,F_1杂种有较强的苗期优
Abstract:A male sterile plant of mustard was found in 1973.After several years of study,ams line,European-Xinping A,a maintenance line,European-Xinping B,and arestoring line,74243-6,were successfully developed and a set of “three lines” was ac-complished in 1975.The set manifested high stability of sterili
