玉米自交系铁7922株型紧凑,茎秆坚韧,品质优良,配合力高,抗逆性强,遗传性状稳定,适应范围广,是国内改良Reid类群的骨干自交系之一,同时也是选育玉米自交系的优异种质资源。许多育种者围绕铁7922的改良创新,选育自交系达40余个,组配的杂交种通过国家和省级审定有60余个。其中代表品种有铁单10号、铁单12号、铁单15号、铁单18号、丹玉26、丹玉39号、丹玉69、辽120、通吉100、沈玉22号、濮单3号、濮单6号、东单8、东单13、东单60等。可见,铁7922衍生系在玉米生产上同样有着重要的地位。
The inbred lines of maize inbred line 7922 are compact in type, tough in stalks, high in quality, high in combining ability, strong in resistance, stable in genetic traits and wide in adaptability. It is also one of the backbone inbred lines of domestic improved Reid group Excellent Germplasm Resources of Maize Inbred Lines. Many breeders around the iron 7922 improvement and innovation, breeding more than 40 inbred lines, with the hybrids approved by the state and provincial examination of more than 60. The representative varieties include Tiedan 10, Tiedan 12, Tiedan 15, Tiedan 18, Danyu 26, Danyu 39, Danyu 69, Liaowan 120, Tongji 100, Shenyu No. 22, Pu Single No. 3, Pu No. 6, Dongdan 8, Dongdan 13, Dongdan 60 and so on. Visible, iron 7922 derivative system also has an important position in the production of corn.
