用秋水仙素、MH、DMSO等药物处理玉米京黄13、八趟白、金皇后3个材料的未授粉的雌穗花丝诱导孤雌生殖,获得结实,并从中选出19个纯合二倍体。发现纯系频率以单交种京黄13最高,以40ppm MH加2％DMSO的诱导效果最佳。经过鉴定证明这些纯系在纯度、遗传稳定性和配合力等方面均可以与常规自交系相比拟。本文讨论了所用药物在诱导玉米孤雌生殖中的作用和纯系产生的可能途径,以及由此产生的纯系在育种中的应用价值。 Treated parthenogenes with non-pollinated florets of maize Jinghuang 13, eight triplicate white and golden queens by using colchicine, MH, DMSO and other drugs, body. The pure line frequency was found to be the highest in single crosses of Jinghuang 13, and the induction effect of 40ppm MH plus 2% DMSO was the best. After verification, these pure lines can be compared with conventional inbred lines in terms of purity, genetic stability and combining ability. This article discusses the role of the drugs used in inducing parthenogenesis of maize and the possible ways of producing pure lines and the application value of pure lines in breeding.
